I have a 1998 F150, had this truck for just shy of 200,000 miles, never a major problem and now she's killing me. Turn the key, no crank,no start, the same time this started the radio also quit working. I can start her with a screw driver at the soleniod (new by the way) runs perfect after that. By the way it's a 2 wheel drive with the 4.6 v-8
View 1 RepliesI just got a 1998 F150 5.4l 4x4 autotragic. Was sold to me as needing trans, wouldn't start. Tossed in a new starter and solenoid, now I can hear the the starter turn crank pulley turns maybe a quarter inch and when I let off the starter it goes back to the same spot.
Fear is motor is locked, but question (i don't know automatics) is there any way that a bad trans could keep a motor from turning over? Truck rolls in neutral or drive, pulled the drain plug no water just oil. Tempted to just buy a running 5.4 with trans but if I can avoid that I'd prefer to.
1998 Ranger, 3.0 liter manual transmission. The vehicle recently has had the engine replaced. Still a 3.0 Liter, but possibly is from a 1995 or 1996 Ranger. Replacement motor from a wrecking yard, appears to have been sitting for quite some time prior to purchasing. I had a friend change the motor out after getting the vehicle a few weeks ago.
Ranger drove fine for a week, but this morning it wouldn't start. One click is all it would give when you turned the key. Thinking the culprit was the all in one starter/solenoid, I replaced it with a new one this morning. Now the solenoid will click continuously when the key is turned, starter still will not rotate then engine.
Battery tests good - 12.4 volts; connections appeared fairly corroded.
Here is what I have done:
- Clipped off the first half inch of corroded terminal leads, replaced both sides with new battery connectors and wire brushed connections off at battery and starter.
- Replaced Starter
- With "S" connector disconnected, attempted to bypass starter connections and short terminals to see if a faulty clutch position sensor was to blame; shorting did not produce anything other than turning the key did.
- Paralleled an additional cable from battery to starter terminal to see if corroded wire connections were to blame; still just clicked repeatedly when attempting to start.
Crankshaft does rotate manually, does not appear to be seized up. Unsure of what else to check for. Not confident in friend's engine installation abilities, he may have screwed up something I'm not thinking of. On the other hand, I don't believe I would have been capable of swapping out the motor myself.
I am having problems with my 97 F150 6cyl. A couple of months ago, I noticed the truck after sitting for a few days without being started would not crank. After some trial and error, I found that turning the ignition switch on and off several times did the trick and the truck would crank right up. I was thinking this might be a fuel pump or fuel filter issue but, I'm not sure.
A couple of days ago I was going to drive the truck and did the ignition switch deal as usual and the truck cranked up but, there shortly after while just idling the motor died. I have tried and tried to crank it and it want start back. After thinking on it, I don't know if this is a fuel problem or not, or maybe even the ignition box.
I picked up a nicely used 98 XL in Alabama yesterday, with 106k original miles. The dealer threw in FREE oil changes for life with my purchase, but I don't see me driving 2.5 hours to Alabama for that.
It's got crank up windows, manual locks, standard tranny, 4.2 V6, and the regular seats. Yep, pretty basic. It came with a matching fiberglass shell also. The only things wrong are the radio volume doesn't adjust, and the rear window frame appears cracked. These are minor in my opinion.
What drew me to this truck was the beautiful condition it's in and my love of this body style. What would be added to improve creature comforts, performance, etc.
If I turn on my ignition switch and my gauges go to where they're supposed to be, the truck will crank. If I turn switch and , lets say gas needle for example, the needle goes to full then drops back to empty, the engine will turn over but will not crank.
View 2 RepliesI am working on a 2000 f-150 XLT 5.4L 4x4 Automatic. It tries to crank over but acts like its stuck. things done: New starter, new battery, fixed connections. I can turn the crank counter clock wise but won't turn clock wise. Not sure if i should say the engine is bad or could trans be stuck? Heard 5.4L's have timming chain issues. Is that true? Point me in a direction and i'll go forth.
View 14 RepliesI have a 99 f150 2wd v6 4.2 liter engine. Im going to sum up what happened and what I've done so far. One morning truck wouldnt start. Wouldn't crank, turn over, or even make a click click noise. I tried jumping it just to be sure but it didnt do anything. Battery is fine, interior lamps, displays, and radio all work fine.
I took the starter off, had it tested, it was bad so i got a new one. Still had the same problem. Finally, i got underneath the trunk and bridged the positive and negative on the starter solenoid and it fired right up. So the starter is not the problem.
Next I looked into the starter relay, if I bridged the positive and negative on the starter relay it fires right up just like the starter. But since that is only bypassing the starter relay, it didnt tell me whether the starter relay was good or bad. So I got a new starter relay and it worked! It started with the key with no problem 3 times! I thought the problem was fixed but when i tried to start it an hour later, nothing... Same problem as before.
I checked all my fuses, none were blown.
I'm under the assumption that either something leading to the starter relay is making the starter relay go bad OR there isn't enough power going to the starter relay. Maybe something in the ignition, even though my accessories are all still working.
It is the only vehicle I have to and from work. For now I am getting by with bridging positive and negative on the starter relay to start it but that is only a temporary fix.
I have an 02 f150 5.4 4x4, drowned it a while back, thought i had hydro lock, crank can be turned by hand though as far as i can with a wrench, so internals seem to be fine, no bent or broken rods that i could tell, ripped everything apart cleaned it up put it back together, new fuses, new ignition relay, new starter, alternator and battery as well, turned the key to on and got all my electronic stuff back up, turned to start and it all goes dark, which i assume is because at that point its sending power to the starter, but the starter didn't turn or crank the engine...
So question being when i put my new starter on is it possible that i might have crossed a wire or something that would cause it to not crank? and due to the fact that I had water in it, and had hydro locked it, all my plugs are out, now I know that spark is needed for the engine to run, but shouldn't be needed just for the crank to turn right? question being is that once i fix the wires on my starter, I am looking for initial crank before start up, so do i need to put a plug or two back in and hook them up to make it crank? or will it crank without them? and yes I did replace all my fluids as well.
So she will crank all day but no start. Theft light is going nuts like I am trying to steal my own truck!! I've read it could be a PATS issue.
However after I unplugged my pos batt cable and hook it right back up she starts like nothing ever happened.
its only happening every once in awhile. but it does get old. I have been just leaving my pos cable off whenever I shut the truck off.
Took my dad's snailblazer (trailblazer) since the 4.2 i6 in it gets better mpg than the old worn 5.4 in the f150. Well I didn't leave much gas in the 30 gallon tank about 1/4 tank or 7 1/2 gallons. My dad took it to the gas station on Friday and filled it to 3/4 of a tank. Got back in the truck and attempted to turn it over and got nothing.
Battery cable was a bit loose from what he told me, so he tighten it up. Nothing. I know the fuel pump is still going cause when you turn the key forward you can hear it whine. Starter is only a few years old maybe 6 or so. Not sure if that went bad or something else.
Last time something similar happened the A/C compressor seized up and wouldn't allow the engine to turn over. Well we eliminated the compressor around '09 and bolted a pulley in its place. Off the top of my head I can't think of anything that would have seized up causing this.
I have a 97 F150 w 4.6L engine with auto trans which I bought new and has approx. 150,000 miles on it. Very recently it would crank and crank and not start or sometimes would start. In searching through multiple threads on here many of the Ford techs recommended replacing the IAC valve as a cheap and easy to do fix and I did that. The OEM factory IAC valve appeared to be dirty with black soot. I also cleaned the MAF sensor in the air filter snorkel. I also replaced my very old battery at the same time. I verified that the fuel pump was running for about a second or two and shuts off after the ignition switch was turned to ON so the fuel pump is running since I could hear it. I replaced he fuel filter several years ago so it should be OK and not plugged.
I had to use starting fluid after the battery replacement to get the truck running but after I got it started and I did several driving cycles over three days to make sure the truck computer reset properly and the truck was running fine and starting without a problem. I was checking the starting every 4 hours or so for the first two days and it would start on the first crank every time without a hiccup.
This morning on day 4 when I went to start it the same problem occurred where it would crank several times and not start. I loosened the filter snorkel up and shot some starting fluid in there and it cranked up after a couple of tries and ran fine all the way to work. It seems like I have a fuel delivery issue of some type. I know the fuel pump is inside the tank and very expensive to replace if it turns out that it needs replacement. That is definitely beyond my capabilities. I plan to check the fuel pressure this weekend when I have a chance and can rent a gauge from Autozone.
My question is this: If it turns out to be a defective fuel pump can I just add an inline electric fuel pump outside the tank and have it pull through the tank in the pump leaving the in-tank pump abandoned in place? Are there any other sensors or parts I should be checking for voltages, resistance, etc. that would affect fuel delivery for starting? The truck seems to run very well with no misses of any kind and accelerates nicely after it starts. Also, no "Check Engine" light at any time and the bulb is working since it lights up momentarily when the ignition is turned to ON position.
Update Saturday June 25 - Got a fuel pressure test gauge and got the following results after installing a new fuel filter:
1. Bled off fuel pressure to connect gauge and after 5 or 6 Key On, engine off cycles the pressure came up to about 38psi and truck started up fine after pressure was at 38 psi. The pressure built up slowly after the bleed off with each ON/Off cycle and that is why it required 5 or 6 cycles to reach 38 psi.
2. Key ON, engine idling maintained 31 psi
3. Key ON, engine revved up slightly maintained about 31 psi and seemed to stay there even with more throttle increase.
4. Key ON, engine idling, disconnected fuel pressure regulator line and pressure increased to about 40 psi and stayed there
5 . Left the gauge connected after turning off engine. Key OFF, engine off, after 1 min fuel pressure increased to 33psi. It is about 90 degrees in the shade here today.
6 Key OFF, engine OFF, after 2 min gauge read 33 psi, after 5 min increased to 34 psi, after 15 min decreased to 33 psi, after 30 min decreased to 29 psi, after 45 min decreased to 26 psi, and after 60 min decreased to 23 psi. The pressure seems to decrease slightly with time which I think is what it is supposed to do. Is the pressure decrease rate too fast or about right?
The truck seems to be running fine and starts up immediately after sitting for a few hours but I am making sure to turn the key on/off for at least one or two cycles to build up fuel pressure and the truck starts every time for the last week. Does it seem like my fuel pump is OK or not? Fuel pressure regulator OK or not? Any other diagnostic tests I should run?
My t case will engage in 4 high and 4 low. so i know the switch and motor works because it go all the way to 4 low and i can feel the lower gears. BUT the front drive shaft is not turning because i know that the front diff is engaging just fine cus one I just fixed it and because when i put it in 4x4 the front drive shaft is locked in but when i take it out the drive shaft moves freely when i turn it by hand. But when I test it in gravel or mud the front wheels still ain't turning. So its gota be the t case. But what are the part that may be broken in the t case and if I can fix it wile its still on the truck.
View 4 RepliesI have a '99 F-150 with 4.6L V-8. The truck has run perfectly since I bought it a year ago. My grandson took it a short distance to a neighborhood store, and when he got back he parked on the neighbor's lawn.
IMMEDIATELY after turning it off, I told him to move it, and it would not start. Wouldn't even turn over. I did a little research, and replaced the most likely culprit, the starter....no change in condition. When keyed to start, the dash lights up, but that's it! I did get under the truck and there IS voltage getting to the large power lead.
The starter has it's own solenoid, however there is another one mounted to the firewall. Does this have anything to do with the starter?
My 1999 F-150 is having an issue after a tune up; changed coil pack, plugs and wires. It started and ran fine before, but after the tune up it doesn't even crank, just clicks and clunks. I hear a whine from the alternator, but last I checked (a couple days ago), it tested fine so I dunno if it went bad.
I thought it was PATS, but the theft light turns off when the key is in the on position and the fuel pump primes. I dunno if it's the battery, but it tests out OK with my voltage tester (12v+) But it may not have the amps required.
If the coil pack isn't grounded right, like if the platform it's on is corroded, would that cause this issue?
I left my F150 to sit over the winter parked near my house. Battery was bad when I went to start it a few weeks ago. Got a new battery, threw it in, but still no start. It wouldn't crank.
Went to work on it today and the battery was totally dead, took it to schucks and they said it was bad. So I got it replaced with a fresh one and I'm still getting the same thing.
Turn the key on and accessories come on, turn it all the way and nothing happens, except for the aftermarket radio turns off. I replaced the ignition switch last year. I tore apart the dash to see if that went out again but it looks fine.
What should my next step be?
I am having problems with my truck not sure where to start. It was my everyday truck until one day I got ready to leave for work and the truck wouldn't say anything. It was getting power but no crank no start. Called tow truck he checked battery said that it was good. I got home tried to start truck and it started. I drove to the store and it did the same thing no crank no start. It has 110,000 Sigle cab manual windows...
View 2 RepliesI have a 2002 F150 5.4L (VIN-L) that has been sitting in the driveway since February. I have been a mechanic for 30 years for large commercial trucks, and my own truck has me stumped. I'm sure I've forgotten something but I'll try to list everything I have tried so far. It started with crank no start, no check engine light, checked for trouble codes got a trouble code for the CHT(cylinder head temperature) sensor.
- Replaced the CHT sensor. Cleared codes.
- Dash lights up fine, shows mileage, and anti-theft is not flashing while cranking.
- Fuel Pump does not seem make any sounds. Hit the tank with a hammer. Nothing.
- A little fuel comes out of the schrader valve on the fuel rail when I push on it. I have not checked it with a pressure gauge.
- Attempted to start with ether, nothing, so I'm assuming no spark.
- Fuel pump inertia switch isn't triggered.
- Checked several ground connections to the frame and checked ground connections in the PCM harness. All have less than 5 ohm resistance.
- Unplugged and plugged back in cam shaft sensor.
- Checked voltage on the TPS(throttle position sensor) I'm unsure about the results, if the TPS was bad wouldn't it just idle funny and/or stall?
Fuel Pump and PCM relays in the underhood fuse block appear to be good. All other fuses and relays appear to be good. I have been swapping the relays with one I think is good, although. Searched all over for additional relays, and found 3 inside the cab behind the passenger air-bag. Can't seem to find anything in the Haynes/Chilton manual that lists what they do. They are about half the size of the fuel pump relay.
Manually grounded the fuel pump relay, relay clicks but I don't hear a buzz from the fuel pump. Id like to run 12V to the fuel pump directly to see if that's my issue, but I'm not sure where to connect it without frying something important.
I bought the alldata.com DIY guide for my truck and it hasn't worked much. I have read extensively about others with similar problems and I just don't know what to do next. My main question here is, if the fuel pump is bad, would that stop the spark plugs from working? I'd rather not replace the fuel pump without being absolutely sure.
I have a 97 f150 with a 4.9..... I drove it less than a half a mile and shut it off. when I got back in it to start it up it wouldn't do anything like the battery was dead but all the electrical worked but it would not turn over. after about 4 hours when I returned, it started just fine. drove it straight home and shut it off and immediately tried to start it again and had the same issue. What the culprit may be ?
View 1 RepliesOk I have recently bought a 1998 Ford F-150 V6 4.2L 2WD and when the guy sold it to me the check engine light was on and he told me that randomly when you turn the key to the on position you will not hear the fuel pump buzzing sound and he knew it wouldn't start, he said you would have to turn the key from the on and off position many times until you hear this sound and then the truck will start and run fine.
First off I got the codes read and there were three of them P0171, P0174, and P1537 some things to note are that the drivers air bag looks like it had deployed, the cover is loose and when I pulled it back the air bag looks duct taped up inside there that would cause the air bag light to continuously flash while driving. I noticed the battery leads were corroded so I replaced the battery and put new battery clamps on both wires, after that the problem did not happen for a week and I though it was over but it happened again.
Next is that the truck has the PATS system and it did not come with a remote which I have also read that the PATS system can cause the fuel pump not to turn on but not sure if this would cause it to not start randomly because sometimes it starts right up. When I started to look at the simple things to fix I noticed it did not have an air filter in the housing. so I thought the MAF sensor could be dirty so I cleaned it with the special cleaner, I put sea foam into the intake via a vacuum hose and also have put a fuel system cleaner in a full tank and have driven most of the gas out. After putting in an air filter, cleaning the MAF sensor, and sea foaming the intake, it seems to run a bit better but I am still having the random fuel pump issue.
I have checked the fuses and the and the fuel pump and ECM relays both are fine. Today I put new exhaust on it because it had some bad exhaust leaks and the truck did not start again, so the guy trying to put my exhaust on, hit the fuel tank with a hammer and it didn't work then hit it again and it finally worked. Im not sure if the hitting it did it or if it just randomly turned on like always from turning the key on and off. The new exhaust has made a huge difference in driving it feels and sounds much better.
Also to note is that when I am stopped at stop lights it will idle at about 1500 and then it drops down to 500 and back up and back down again and it does this at most stop lights, and it is not an abrupt drop it just slowly idles down and back up again. Again once the truck is started it runs perfectly fine with no issues, and there are no specific times when it has the problem it seems to be randomly. I know that many people will tell me to change the fuel pump out and I am already prepared for this but if there is any easy things I haven't thought of yet...
i have a 99 f150 with a 4.6 that will not start. it has sat for a while now. when i go to turn the key to turn it on it cranks and cranks and cranks but wont start. the theft light blinks like crazy and the odometer reads dashes. There is also a relay which i do believe is the pcm relay that clicks like crazy. when the relay clicks and the key is first turned to the on position the fuel pump will turn on and off as the relay clicks.
We tried putting a scan tool to it to try to pull a code and the scan tool wont connect. I do believe its the pats system kicking, but i also think its related to this relay clicking like a mother, maybe a bad connection in the junction or something. But I am not really sure how to try to start and find the problem. i have also tried replacing the relay that clicks and the new relay does the same thing.
