Ford F-150 - 1997-2003 :: Engine Cranks Over Fine But Won't Start?
Oct 23, 2013
The 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?

My 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.

I have a 98 F150, 4.6L with approx. 245,000 miles on it. recently it started, then studdered a little bit and died. I managed to get it re-started, it then shuddered a little more although I was able to drive it back up the drive way and park it. Now, it will crank however it does not even attempt to fire. The sound that it makes when trying to start seems odd to me. Like the engine is just turning against a constant resistance instead of the normal starting sound. I tried shooting a little starter fluid into the throttle body and nothing changed. I pressed on the shrader valve and got a spew of fuel to come out so it seems that it might not be a fuel problem though it sure sounds like one. Just curious, what are the symptoms of a truck with no compression?

I 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.

2000 F150 4.6L Romeo 2WD. Engine cranks great. Fuel pump working. Changed fuel filter. Will not start. No codes. Fixed A/C day before yesterday, only had air coming out defroster, disintegrated vacuum hose at firewall. Ran errands yesterday, no problems whatsoever. Get in truck today to go to work and no start at all, engine turns over fine. What next?

I'm a relatively new F150 owner (just got rid of the 98 Ranger I drove since 99), so I thought I'd check in to see if I was overlooking something obvious. A few days ago, after driving to the store with no obvious issues, I went shopping (coincidentally for oil change materials) and when I returned to my truck it would not start.
Here is a bit of info:
Starter cranks over the engine.
Battery is relatively new, and has plenty of power.
I can hear the fuel pump kick on briefly.
Check engine light is on (EGR Valve fault).
Engine started with starter fluid.
Engine ran like normal after starting.
Finally, the vehicle started/ran fine for a few days before the issue occurred again.
Like I said, I'm not too familiar with the vehicle yet, but I'm assuming the issue must be with the fuel delivery system. I plan on replacing the EGR valve, but I am curious whether a faulty EGR valve cause a no start? Also, I'm wondering if it's more likely that the fuel pump is going bad, or something electrical is the problem since I'm under the impression that the engine stops sending fuel to the cylinder if/when the engine doesn't start quickly after turning the key.

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.

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.

I'm TSing a no-start on my 2005 6.0L F250. Engine cranks fine. I've been working my way thru the TSing guide and using my new ScanGaugeII. No codes found. At glow plug warmup, (dash light goes off), I'm getting 40.5v FMP, 11.0v FLP, 14.8% ICP, and 0psi IPR. After cranking for 10-15 sec, get 35.5v, 10.0v, 84.7%, and 446psi. I've had a trickle charger on all night to keep the batteries charged. Have not seen FMP over 45 or IPR over 470.

My 2001 Accent GS (1.6L DOHC) wouldn't restart after a short 2 mile trip to a local store. The engine cranks fine but doesn't fire.
It has had a CEL issue for awhile and after it wouldn't start I checked the codes and got:
303
335
722
I replaced the Crank Position Sensor and Fuel Filter but it still just turns over.
I hear the fuel pump run when I turn the key on and I broke the fuel line and it is Pressurized, so I doubt it is a fuel issue.
The 722 code indicates the output speed sensor has an issue. Need to know definitively if that sensor is completely shot could this prevent the ECU from firing the engine?
I have had this car since it was brand new and I'd like to keep it going a little longer.

I'm trying to diagnose a no start issue on my son's 1997 F150 4.6L W code motor. It quit on him while driving and we haven't been able to get it re-started since. We immediately assumed the fuel pump was bad as we were not getting any fuel pressure and we cannot hear the pump running at key on. So we pulled the pump and bench tested it, and the pump itself seems fine.
We then checked for spark, we have spark in all cylinders. After that we started checking fuses and #30 under the dash was blown. We replaced that and it blew again at Key on. We ended up going through about a 1/2 dozen of them while poking and prodding at misc. wire harnesses trying to figure out why it keeps blowing. Today we put a new one in and have tried restarting and that one is not blowing anymore, but we still cannot get fuel pressure. We've checked all fuses and swapped relays around. We noticed that under the dash #20 and #21 do not have power, but the fuses are ok. Are we finally on to something here?

Had the Excursion out today. Made a stop coming back and used the remote start. I entered the truck and by mistake pressed the brake pedal which shuts off the engine. When I tried to start the truck with the key...it cranks fine but does not start. It'll try to run, sputter...but will not run.
I cannot hear the pump running when the key is turned. It was towed home and it in the driveway. I assume it's the fuel pump....but wondered if the remote start/alarm could be killing the power to the pump? The cut-off switch in the passenger footwell is pressed in. Where do I start:?

This has happened twice in 3 years....I get regular service from a Ford dealer and am overdue.... I think it may be temp related. Has been below freezing the last few nights. Truck was parked on an incline during the last two "shutdowns" ( engine lower than bed slightly), I drifted to a level position and it started. This has only happened twice previously. Now it seems to be a permanent problem but I am unable to get to the dealer without a tow... which I am trying to avoid.

I have a 2001 F150 Supercrew Lariat. About a month ago I stopped to fill up with gas and afterwards it would crank but not start. After a few tries the engine would no longer turn over. My battery was 7 years old so I replaced it and the problem went away for about 5 days. Then the same thing, crank but no start. I checked all the fuses & called the local Ford dealer.
After talking with the parts dept. I tried hitting the panic button then the truck started. After talking to parts again I replaced the PATS transceiver. After 3 weeks with no issues the problem came back. This time I locked the doors with the keyless entry remote then unlocked them & the truck started. So I'm wondering what is my problem. Could it be the PATS module or something with the keyless entry module or some other issue.

Several months ago, my truck begins having starting issues. Intermittently, the truck will not start, even though it cranks fine. I have done the following:
- checked inertia fuel switch. Okay.
- checked connections under hood for corrosion. Okay.
- checked fuses & start relay. Also swapped relays with no luck fixing the problem.
- sprayed water at various locations under the hood and bed, since the problem occurs more often when raining. No luck stressing the problem.
- changed fuel filter a couple weeks ago. No luck fixing the problem.
- changed battery over the winter (due to my 8 year old battery was becoming weak). No luck fixing the intermittent starting problem.
- changed the starter a month ago (since the truck stopped cranking). No luck fixing the intermittent starting problem.
- Installed a fuel pressure gauge on the fuel rail.
- Tried banging on the fuel tank with a rubber mallet. No luck fixing the intermittent starting issue.
When the truck refuses to start, the fuel pressure reads 0. Sometimes I can wait 5-10 minutes, and it will start. The truck runs fine after starting.
Sometimes waiting 5-10 minutes will not solve the problem (fuel pressure remains 0). Then, I hook my battery charger to the battery, and the voltage climbs from ~12.5V to 14.7V. The fuel pressure climbs to 30, and the truck starts.
I'm apprehensive to change the fuel pump, since it seems like more an electrical problem than a pump problem. Any diagnostic test that will tell the true problem source?

Here's the deal. Ive got a 2000 f150 4.6 4x4xlt 170000 miles, About 2 ears ago or so the truck would not start on the first try or two. now this only occurred every once and a while. Last winter it became more of a problem. All i had to do was cycle the key a couple times listen for the pump to prime and was good to go. Summer rolls around no problem at all. Fall rolls around and here we go again no prime. cycle the key a couple times good to go. As it gets colder the problem gets worse. No we fast forward to couple a weeks ago, was out in the woods cutting firewood i go to move the truck and it wont start. I have to cycle the key like 30-40 times. Now its doing it like every time i go to mov the truck until yesterday. Now it wont prime at all. Now every time it primed in the past it runs perfect after it starts . the filter has been changed every 12-15000 or every fall, Ive replaces the fuel pump relay to try it no change, tryed the other key no difference. Im leaning towards a pump but ive never heard of one doing this before.

About a month ago, my 2001 f150 supercrew (4x4 5.4L) didn't want to start one morning. This was after a very cold night (15 degree temps). It sounded like it had plenty of juice in the battery (cranked good), just wouldn't start. Later in the day, after it warmed up, still no start. I dug thru here, and someone recommended disconnecting the positive battery cable for a minute then retrying. I did it, and it worked. All was good.
About a week ago, no start in the morning again. Tried the positive cable disconnect, no luck. After several hours, it just seemed to randomly start, and all was well again.
Today, truck started right up in the morning, but later in the afternoon (warm winter day 45 degrees) no start. Tried the positive cable disconnect, no luck. After screwing with the truck for about an hour, I decided to put the fuel pressure gauge on the rail. NO fuel pressure.
Is fuel pressure associated with the PATS, or is this a straight up fuel system problem?
Additional info: My gas tank fell out this summer, (recall on those tank straps), and I had a new tank, pump, straps and lines installed. I had a no crank, no start issue this summer, but that turned out to be the transmission not registering in park. I assume the two issues are unrelated.

This 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.
