Ford F-150 - 1997-2003 :: 2001 - Cranks Intermittently But Not Starting
Jan 14, 2015
I have a 2001 F150 XL, 2WD, 4.2L, Auto at work. It will intermittently crank but not start, also, my scan tool will sometimes not connect to the truck. The only code I ever get is 1 about not being able to connect to self diagnostics. I have narrowed it down to the PCM relay in the underhood power distribution module not turning on because it SOMETIMES only sees a 2 volt turn on signal instead of 12 volts. I have replaced the ignition switch on the steering column- initially I thought that took care of it.
But as I was about to put the meter away it did it again. If I remove and reinstall the diode that is in the PDM, sometimes more than once, I can get it to turn on. Are these diodes available from any one besides Ford? The wiring diagram in my Haynes manual is very generic and does not show the circuit from the ignition switch to the fuse box. Where can I find a GOOD and complete wiring diagram for free on the net so I can print it out and take it with me to work?

The past week or 2 I have had an intermittent starting problem. Engine is turning over but wont start, but after i wait a second it will start up. I listened to see if the fuel pump was running and heard the whine. I checked the battery and the starter voltage and it was all good. i primed the fuel pump a couple of times and it started up on the first crank of the ignition. The truck runs great when driving and idling, no misses or loss of power that i have felt or heard yet. I am thinking it is either the fuel pump is starting to go or maybe the fuel filter is getting a little clogged up. Like i said up above this is an intermittent problem and that is why I am confused. Its a 2001 F150 4.6 4X4 ....

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?

I have an issue with my 2001 f350 7.3 PSD. Intermittently it will not start. It will crank really quick, but will not even try to start. I think it is not getting fuel. There are no CEL codes and I have a WTS light and the tach is moving while cranking. I hear a clicking/buzzing sound coming from under te center opf the dash. When I hear that sound it will not start. checked fuses and relays and it started before. not sure if removing the fue made whatever reset. this has happened a couple times. Now it will not reset. When I remove the number #24 fuse under the hood, the clicking stops. when i crank it, but still doesn't start. When it starts in runs perfect. Drained the batteries trying to trouble shoot, but have them charger now.

I own a 2000 f-150 7700 series with a 4in body lift. recently Ive had a problem starting (I believe it is from the shifter not recognizing im in park) but now my theft light flashes at me and there is a weird sound that sounds like a relay from under my steering column when i roll my windows down, move shifter around or turn on 4x4. also my radio stays one every once in a while after the key is turned all the way back to off, and windows wont roll down after i hear the relay sound. Ive read to tighten shifter linkage and will do that tomorrow to see if that fixes it.

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.

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.

01 supercrew 4.6. Have had intermittent no start. The first few times it did start with a jump. Cranks fine but I thought the battery was weak. Replaced battery, same issue. 40 psi gas pressure at the fuel rail with analog gage. Theft light blinks with battery inserted. Theft light not illuminated while cranking. Battery light flashes while cranking. Battery is brand-new and charged. Opened and closed inertia switch several times to check.

Doing some research for my dad, we got a 2001 F150 with the 4.2L v6. Recently, we've been having an intermittent starting problem. It'll start, run & drive perfectly with no problem some days. Then some days the truck wont start. It will crank perfectly fine, sometimes start & then run rough for about 5 seconds then die again. Usually happens when the truck is warmed up & has been started, driven & shut off multiple times. We've replaced the fuel filter & the pcv valve i believe & still no luck. We take it to our mechanic & it starts right up every time for him. This problem has me, my dad & our mechanic stumped.

I have a 2001 F150 Supercrew that cranks but will not start after a hard rain. The mechanic checked the gem module and the fuse box, the gem module looked good but the fuse box had some corrosion he thought from water so he replaced the fuse box and had a body shop reseal the windshield. The first time it rained it started right up but after the next rain it would not start. I went out 12 hours later and it fired right up. I wonder if I would be better off taking to a Ford dealer. What to do next.

Just recently got a sweet deal on an 01 Lariat with a very low mileage 5.4L. I almost didn't purchase it because the oil pressure gauge will not read when you start the engine. Sometimes it will sometimes not.
When it does read, it is just past half which is the normal reading. When it doesn't read, it shows zero and the light is on. The engine runs fine either way, and the previous owner said it has been that way for years. The engine has been well cared for, and has been running Mobile 1 full synthetic for most of the 80k miles. The oil was not overly dirty at purchase, so I figured it to be a loose connection. I suffer from the cold solder joints that these trucks are plaqued with, as evident by the intermittent odometer reading. Do you think the oil gauge issue is the same thing? A cold solder joint? Or should i just start with a new sender?

I got an 2001 f150 4.2l v6, 5speed. It started running real rough almost like it was hitting on only 3 cylinders I replaced the crank sensor and did a tune up on it along with a new coil pack and now it won't hit a lick the plugs are getting fire, it's getting fuel but, will not start it's not throwing any engine codes. Which leads me to believe it may have a bad ecm.

I am having trouble with my truck not starting. The issue has been occurring on and off for over a year. Usually, it happens about once a month, regardless of weather.
I turn the key, and there is one click. Usually at this point, I can use one hand to gently pull the shifter "up" towards park and turn the key again and it will start. Recently it is not starting when I do this. I have tried many times, and have tried to start it in Neutral (is that even possible with an Automatic?).
With the key in the "ON" position, I go under the truck and jump the starter cellinoid. I am jumping the small post to the big post where th wire comes from the battery. I do not touch the post that the wire goes into the starter.
I am very confused because it starts just fine without fail and almost instantly when I jump the posts. It is drive-able this way, but I would like to resolve this issue, and resume using my key to start it since the issue doesn't seem to be resolving itself as it usually does.
A friend told me about the Ignition Starter Switch inside the Column. If I have time I will attempt to start the truck with a screw driver on the switch tonight to narrow down the issue.

I drive a 2001 ford f150 lariat 5.4L. My truck will crank but not start, i am getting complete spark, and have ran a full fuel pressure procedure, and am getting complete fuel pressure, there is no water in my gas, everything checks out how it should. I ran a test on my cluster and it showed a code that said i am not getting connection to computer to start. I removed the cluster and repaired all loose wires properly, and it still wont start! I have had many people look at it and they said it could still be a bad cluster.

My 2001 4.6L F-150 has been sitting on the driveway, used once every 2 weeks or so for the last 3 yrs. I came to start it a few days ago and it kept turning over but not starting. The key security chip is working, battery is charged, all plugs are firing, fuel pump fuse and relay check good. When I turn the key to ON, sometimes I hear the fuel pump priming, other times it doesn't. The times it does prime, the truck fires right up.
The times it doesn't prime, engine won't start. When the pump does prime, and while the engine is running, the pump makes a noticeable buzzing sound, much louder than normal. When the pump primes. fuel pressure measures at 42psi in the ON position, 36psi with engine running, and 46psi with engine running and vacuum hose removed. I believe all these are within specs.
My question is this: Is it safe to assume that the pump is going bad and will eventually fail completely? My second question is (and I know this can be debated til the end of time) should I get the Motorcraft or aftermarket? I have Airtex, Spectra, Carter, and Delphi available locally.

I have a 2001 F350 V10 Crew Cab that has 51000 miles on it so it doesn't get driven all that much, but I do start it at least once a week and it has always started on the first crank.
A couple weeks ago I drove over a friends, I backed up her driveway, turned the truck off and went inside. After returning I went to start the truck and it wouldn't start, just cranked. Probably had between 1/4 and 1/2 full.
I let it coast down to the level and it still wouldn't start. Finally had it towed home. When I got home I tried it and it started right up. Next day it just cranked and wouldn't start. The day after it started right up, I ran it for 20 minutes, turned it off, tried to start it and it just cranked....
Then I started looking at forum's for a possible answer.
I already had an IAC that I bought a few months ago since it was idling a little rough that I installed. Still started intermittently.
When I listen closely when I hear the fuel pump run when I turn the key it starts right up, when I can't hear the pump it won't start.
I have tried moving the relays around that are in the fuse panel on the drivers side hood, moving the fuel pump one to the blower motor and vice versa. Still starts intermittently and only when I hear the pump run.
I looked for the FPDM that in some trucks is up by the spare tire but apparently my truck doesn't have one, or at least in that location..
My next thought is that it must be a bad pump...Can a bad fuel pump act like this, sometimes work and sometimes not?

For the last two years we have been having this problem off and on. The car typically will not start in the morning but 8 hours later it will start right up with no hesitation. The engine always cranks but it will not start. Every time we have the vehicle towed to a mechanic's shop either the car starts as soon as the towing company drops off the car or first thing in the morning when they go to start looking at it. When the vehicle does start there is absolutely no hesitation and no decrease in the performance. The vehicle has never stalled on me, and I have tried pumping the gas and putting the vehicle in neutral but have been unsuccessful in figuring out this problem. The check engine light does not come on and there aren't any codes saved in the memory.

2002 7.3 Power Stroke... I bought the truck about 4 months ago and I absolutely love it but over the last few weeks is has been acting funny at times, it doesn't do it all the time but it has been getting progressively worse, ill drive the truck all day and no problems when I shut it off and go to start it again it just cranks but won't fire.
* Batteries are charged and in good condition, oil is a little dirty but full, I have no codes or check engine light on, and my wait to start light seems to be working fine!
* If I supply a fuel source(starting fluid) the truck will fire but not stay running
* And let it sit for 15 to 45 minutes fires right up like there was never an issue.
* There are no blown fuses
