So after work tonight I went to start truck it turned over fine but wouldn't start, when it finally did it barely ran and then it was fine, I had it b4 when I start it would turn over for a little bit b4 starting, would that be fuel pump?
View 1 RepliesThe Engine cranks over fine, but won't start. When it does start everything is okay and it runs good with no codes. I noticed that by taking the key out of the ignition, I was checking under the hood, and put it back in the truck fired right up. Also it has never done this to the second driver who has a different key. The truck runs fine at all speeds and loads, even when hauling twenty bags of wet mulch. It's a 2001, 4.6 L, RWD. Could the PATS Chip be failing?
View 9 RepliesMy girlfriend has a 2003 f150 4.6lt pick up its a great truck most of the time. Problem is when the temp gets in the neg double digits it becomes very hard to start it cranks fine but doesnt want to fire. When it does fire it might stall a few times before it stays running. The last cold snap we had I replaced the battery and in the summer the starter got changed. I have heard that this model of truck are known for hard cold starts. I am just wondering if this is true and any other thing besides block heater. It is strange that my 89 gm pickup will start no matter what temp and I'm having problems with the newer truck.
View 1 RepliesThis 97 F150 4.2 is new to me, originally a very base 2wd white fleet vehicle, with 189,000 miles, runs smoothly and quietly, idles well, transmission shifts smoothly. Gets reasonable gas mileage.
Problem statement: the truck has an intermittent starting problem. The failure to start happens about 5-10% of the time. The motor will turn over fine, but but immediately stumbles while trying to start. Turn key off and then re-start attempt will be again followed by a bucking stumble. Some times the motor might try and run for 2-3 seconds bucking and stumbling. It is possible the problem happens more often when the truck is warm and has been shut off for 15 minutes or so. Once the problem happens it is very repeatable. It won't start again unless I wait about 30 minutes to an hour. Once it starts it seems to run very nicely. I have noticed some times when I go to successfully start the truck it might run roughly for the first 3-4 seconds bucking and sputtering a bit and then smooth out and not have an issue until the next re-start attempt.
The truck runs so nicely when it is running I doubt it is an issue with the plugs, air filter general tune up. Could it be an intermittent fuel pump issue? The next time it occurs I will check fuel pressure. Could it be fuel pressure regulator? Also tested by fuel pressure. ECU? The truck runs very nicely most of time that seems like a long shot. Crank sensor? Bad fuel? I did add some dry gas.
I have a 99 f350 super duty with a v10. I drove it Friday night, but it wouldn't start Saturday morning. It is turning over fine, just no start. I have no pressure at the fuel rail. The pump does its little key on run. I can hot wire the pump at the tank, and it pumps. It builds up pressure after the fuel filter. I found that out when I changed the fuel filter. Will the pressure regulator shut off the fuel to the rail?
View 9 RepliesMy son's 97 2WD Ranger with 2.3L, 5 speed, no a/c, basic XLT standard cab.
I was using his truck because my 93 Ranger was getting a new starter on it. I drove to work with no problems, then after work, it started just fine and drove a few hundred feet to a stop sign where it promptly died. I was able to start it again with some effort and drove to the next stop sign maybe a quarter mile away. Truck died again, but this time it would not start. Towed it home about seven miles and its in the driveway now. The previous owner had new Motorcraft platinum plugs and wires installed, new fuel filter, fuel injectors cleaned, all about 11,000 miles ago. My son has had it for about 6,000 of those miles.
It felt like it ran out of gas, but the gauge showed about 1/4 tank, and I put about 3 gallons more from a gas can into the tank with no change in being able to start it.
Here's what I've checked so far according to my Haynes manual:
Turned key and listened for fuel pump and it seems to go on just fine.
Checked fuses and they are fine.
Swapped around relays in distribution box with no change
Checked resistance at coil pack and it was about 1.7.
Checked resistance at one injector and it was about 1.7.
Checked inertia switch and it did not need a re-set.
I don't have the ability to check fuel pressure.
We have a 2003 Ford F250 Super Duty, gas engine. This will start fine, then a day later, it won't. Wait 30 minutes, then it starts.
Starter and battery are fine. It acts like it isn't getting fuel. Fuel pump? Filter? What else might cause this?
After the details below, the truck finally started & I let it idle over an hr. Then turned it off for the night. Just to check, immediately tried restarting. Turned over very fast. Started once almost immediately & ran for 1 - 2 sec, then died. After that it turned over fine, but no attempt to fire - just as it's done in the past.
2000 F150, 5.4 L gas. Couple weeks ago it didn't start. Cranked fine - no sign of starting. It did this once a couple mo before that - wife was shopping & didn't start at the store. By time I got there, it had started. Her "solution" was loosened / retightened the gas cap (no, don't know why).
Never found a problem - didn't do it again for months. Then it did. Figured a code scanner would show something relevant to starting problem. It didn't - as far as codes go.
Couple weeks ago, battery was NOT dead by any means, but slightly weak (hadn't driven for couple weeks). I charged the battery (< 1 yr old). Seemed to take charge OK - didn't take long. But, after charging, volts at the battery = 12.8v.
Is it possible that's too low for these trucks & cause starting problem? It turned over quite fast - still no sign of firing. Gas isn't old. New Autolite spark plugs. Clean air filter.
I decided then to use the "jump start" setting on my charger (2 weeks ago) - still didn't fire & made no difference in cranking RPMs. Jacked around that day a couple of hrs. Checked all fuses (inside & under hood).
Bought the scanner - needed one anyway. Actron 9580A. All it shows on codes is a problem ABS wheel sensor (C1230) and a non-MIL code:
P1000: "OBDII Monitor / Drive cycle test not complete."
Suggested fix: "drive vehicle until drive cycle test is complete."
I don't think that's keeping it from starting. No idea about the drive cycle test. The battery hasn't been disconnected OR dead since I replaced it. It's certainly been driven hundreds of miles since new battery. Right after reading the codes today, decided to try starting. Didn't turn over quickly - battery somewhat low after 2 weeks w/o driving.
Surprise - it started - though didn't turn over fast. I let it idle some, then started recording data w/ the scanner. Where a couple weeks ago w/ the engine turning over like mad, it wouldn't start or even fire.
Note: only real difference in today (when finally started) & 2 weeks ago, or the time several months earlier: today is much cooler - in the 60's - vs. 90's the times it didn't start.
So, right back at square one - no signs of what's keeping it from starting. Maybe need some instructions on using more advanced features of the scanner / recording live data (if it starts again).
2002 f150 7700 with 5.4 triton and 4r100 tranny started chugging under acceleration and now stalls when put in D, 2 or 1. park and neutral are fine and reverse works perfectly.
Now when I put it in drive it chugs and stalls immediately... 1/10 times it will keep running but chug violently like its running out of gas. will get worse and stall if you press the gas. i can light the tires up for a block in reverse however.
Changed coils 1 2 and 3, IAC, bank 1 knock sensor, camshaft position sensor
So my aunt has a 2002 ford f150 king ranch 5.4l and a night ago it started this problem which when you put it in drive which she has to put it in 2nd for it when she pushs on the pedal it will rev up to 2500rpms than jerks and goes and its usely fine till she stops than goes and it does it again...
Than today it wouldn't even go in anything but reverse... So than we herd about the Range Sensor on the side of the transmission and it seems like it was it so I unplug it when it was running and when i push on the pedal and it revs up to 2500rpms it will go forward and have power. So we went to get a new range sensor after like 4 hours trying to get the dam thing off and another 2 to get it back on.. I started it up and only reverse works again... So I unplug the harness to it again and we got the gears but 1st and 2nd will just rev and go.
We at a lost right now i even tighten the shift screws under the dash cause our expedition was loose at one time and the gear shifter was loose like hers. But even tighten the bolts it still don't fix the looseness or even the gears.. Is this a transmission problem? OR even the torq covertor?
4 cylinder Japan built camry se manual trans ... 158k miles
Steering got stiff/lumpy driving to work today...trying to figure out if it's the rack or the pump.
Pump isn't squealing but makes a tiny bit more noise when turning left or right(when parked)...but I'm not sure its more then normal.
No leaking fluid. Fluid reservoir is filled to the correct level. No torn boots etx.
Steering feels fine driving straight down the road but when turning it's gets stiff and harder, esp going right.
I've got a 2001 4.6 F150, starter spins just fine, but it won't start. Checked all the basics, but it has no spark, and no pulses at the injectors. Is the PCM dead? Wore out the Haynes manual on this one....
View 12 RepliesSo my "farm truck" is idling very rough, to the point that sometimes that it stalls out. At high idle it runs fine but when its at a idle its very rough. Its been running fine until probably a month ago or so and its just getting worse. What it could be? I am thinking it might be that something is dirty but i just dont know where to start with figuring out what the problem is.
View 9 RepliesI have a 01 f-150, 4.6L, with 160k miles on it. Symptoms: It idles fine with an occasional surge. It sputters in all gears like a misfire (all plugs and COPS replaced 2 months ago). Sometimes it stalls out going down highway or as I turn in my driveway. It also seems like its slipping a little without the "hard jerking into gear". Occasionally the rpm meter will peg low and then return to normal.
The only code that I received was P1451. I changed the canister vent solenoid but the symptoms remain. I've checked voltage on the TPS (the variable voltage checked out but I didn't get the 5V ref. voltage). I've cleaned the MAF sensor. I've also changed the fuel filter. I've resistance checked the connector to the PCM and found several pins that are at ground. I'm not sure what to do next.
I have a 2002 F150 super cab with the 5.4 liter v8. I hit a large water puddle on my way to work Tuesday. I was going faster than I probably should have been. After hitting the puddle the truck lost power. It idles fine but as soon as I put it in gear it sputters and has no power. Also, the O/D drive light is now flashing. What might be going on with it.
View 4 RepliesI have a 2003 Ford Ranger 4X4 4L AUTO. About once every 6 months it will not start. It cranks just fine but doesn't fire. After about 45 min. it start and runs great for an other 6 Months. I have replace the plugs, wires, distributor cap but it hasn't solved the problem. It has had this problem when it is cold and warmed up.
View 4 RepliesI bought a 99F350 with a 7.3, it was not running when I bought it. Batteries good, new starter, turns over just fine, fuel pump works, but now I don't know what to look for.
Was testing ohms for my injectors and at the plug on top of the driver side valve cover, couldn't get a reading at all, tested the ohms at the pass. Side valve cover plug and got good ohm readings.
Truck is a e99 f250sd 4x4 7.3 manual trans. The truck started and ran fine to work this morning. Went to leave this afternoon. Hopped in, put key in and tried to start it. Engine just turned over, never started. Thought that it didn't start because I didn't let the plow plugs warm up enough. Turned ignition off, turned back on and let wait to start light to go out. Same thing happened again. Just turned over but wouldn't start. As far as I can tell the fuel pump is running. Felt it vibrating while the ignition was on. What to check.
View 14 Replies It's a 99 f350 7.3 diesel powerstroke. About 180k miles I think.
It cranks fine. I just changed the glow plugs(all were dead) but when you try and start from cold, it takes about 7-10 seconds to fire. The oil res is full, tried disconnecting the EOP sensor, still fires up and takes just as long. There is one near the oil filter, and that seems to not be it either.
Doesn't smoke, no oil leaks that I know of. Not sure what else to check before sending it to another shop to get put on a diagnostics machine. I read about the IPR, but it has no problems when running. Only problem is a very long time to start. Also changed the fuel filter.
2002 Excursion, 7.3L 375,xxx miles ... As the weather is cooling off, my excursion has a starting problem for a few years.
Replaced all the glow plugs last year. We (my brothers and I) thought it was injectors, but in the summer time or if block heater is plugged in, she starts normally and idles smoothly. And no smoke and runs fine once she warms up.
When cold, it acts like 1 or 2 injectors are not firing. Have run all kinds of cleaners through the oil and fuel.....
Don't want to swap injectors just to swap parts. Would like to diagnose problem....
My dad has a 99 F250 with a no start issue. Everything was starting and running fine one day. The next he gets a no start. Cranks fast and fine but wont fire up and start. He has a scangaugeII hooked up to it and his oil pressures and volts look fine. His tach moves when he is trying to start it. He checked the icp sensor and it had oil through it so he replaced it with a Ford part. Unplugged it and the scangauge pressure goes up but no start. He also replaced the ipr with a new Ford one just in case. He checked and is getting low pressure and high pressure oil.
I am having him check the fuel heater fuse #22 to make sure it is not blown. He had the block heater plugged in all night along with a battery charger to make sure they are topped off as well. We have gone through a couple of the checklists on this site for a no start condition but nothing has solved it yet. I think he is sitting at about 200k on the motor. No major issues or problems until now. He is currently also pulling the ICM to check it out as well. No codes are being thrown.
