Ford Super Duty (1999-2016) :: 2001 F250 Occasionally Starts - Fuel Pump?
Mar 12, 2017
I have the gas 5.4l in my 01 F250 Super Duty. I had to change out the leaking Heater hose before I could attack this other issue. The truck starts when it feels like it. I changed the fuel filter and it started fine. Then the next day it wouldn't. Later it would. However each time it does start it dies when throttled up. I am down to thinking it is the fuel pump. My question is, because changing the pump sucks about as bad as changing the heater hose. Can I install an inline fuel pump and deal with the sump pump in the tank later? Are there any Cons to doing this?

This happens very often when driving around, at first it was only if i stepped on the accelerator to quickly or braked to hard, the check engine light comes on and the truck idles. Nothing seems to be wrong except when i step on the accelerator nothing happens, it lasts about 5 seconds then the light goes out and im on my way. it has started happening more and more just at random times now. it seems quicken the down time if i pump the accelerator.
Second, it occasionally feels like the transmission slips. I'll be driving and when I accelerate the rpms will go up, then what feels like the tranny slipping and the rpms go down. there is a distinct rocking motion when this happens, but it works if I turn it off and on again, or if i just step on the gas the next few miles it seems to subside.

My 2001 f250 on occasion will roll a very uncomfortable distance when I put it in park. Not all the time, but enough to concern me. It will roll a good 12-18" before the park rod or what have you engages. Doesn't seem to be affected by grade. Matter if fact it has always done it on just slight grades. Nothing like a boat ramp. It rolls enough that if someone had been front or back it would have bumped them.

1999 f-250 super duty... okay, here is what i have going on. basically no power to the fuel pump. For the last 2 weeks the fuel pump relay and 1 of the relays behind the radio (next to the blue relay) would chatter and the truck would die. Wait about 5 minutes and turn the key on and if the chatter was gone then it would fire up and run... So NOW no chatter on either relay and not cranking up. - motor turns over just fine- just no power to fuel pump. So I changed out the relay- both behind the radio and the one under the hood. still chatters and no start. i have checked the Inertia switch and 12 volts there... Here is my question, when i turn the ignition on, i have no power to the base of the Fuel Pump Relay.... Where does the power come from to power the relay???

2001 F250 5.4 ... I'm losing my mind chasing a Gremlin. I've been having mostly intermittent starting issues with my truck. I've had the truck for a little over a year, after someone totaled my previous one.
It occasionally wouldn't start on the first attempt, but it got really bad in the last couple weeks.
I first thought it was a faulty inertia switch or wiring in that vicinity, as at one point after manually tripping and resetting the cutoff switch it would start, UNTIL I put the trim panel back. At this point I think that may have been a coincidence.
I eventually probed the switch and it tests as it should electrically.
I put in a new fuel filter and things were fine for several days, but it acted up again. That time was last Saturday. Got it to start and all was good until tonight. Now it won't go, and I've tried so many times that I can see the battery power is dropping.
Last Saturday I pulled the relays from behind the radio and cleaned 'em up real nice. Also, just to check another variable I swapped the two that matched.
I'm about ready to change the fuel pump, but I've heard so many people say they did that but the problem was something else. Not only will it costs hundreds of dollars, its cold out and we'll have to drop the tank in the driveway.
In addition to the relay, inertia switch and fuse, I have found some mention of faulty fuel pressure regulators causing issues. I'll pry the vacuum line off in the morning to see if I can detect fuel residue on the vacuum side. (There is some noticeable corrosion on the fuel rail in that area).
I REALLY want to make sure I rule everything else out before spending hours under the truck in freezing weather dropping the tank and changing the sending unit out.
On key-on there is a noise from the gas tank, but someone else listening described it as a click but no whirring.
I do hear the relay clicking behind the radio. (Also, I pulled them again tonight and put a meter to them. With 12V on the primary side, they click and the other side shows continuity on diode check, and about .2 Ohm on resistance mode.)
I went through a lot of trouble to get my spare out looking for the fuel control module before finding out my truck is about 3 years too old to have one too. What else to check?

I am trying to diagnose my fuel system, but I cant seem to find the fuel pump relay. My truck is an 2004 f250 crew cab work truck with 5.4L. it seems that the relay can be mounted anywhere from behind the radio or in the engine compartment as well as built in to the fuse box under the steering wheel.

The fuel pump fuse keeps blowing intermittently. I would assume it's a wire grounding out somewhere but I can't seem to find one yet. I do have a faulty purge solenoid on the canister but I don't think that would cause this. The reset switch doesn't seem to be tripped either.

Its it true, that the fuel pump relay is hid in the fuse and relay box, and non serviceable ?

I see several threads regarding engines that wont start for no apparent reason. My reason was a failed fuel pump relay. This sucker is hidden in the dash below and to the left of the radio. I got to it by taking out the ash tray. There are three relays under the cover. The upper left is the fuel pump relay. The one to the right is the turn signal relay. I don't know what the bottom left is for.

I have a 2010 f250 6.4 About two months ago the truck just quite on me. I am a farmer in south jersey and have a decent background in diesel motors. First thing that came to mind was fuel. I assumed I was having a fuel issue (clogged filters, failed pump, etc.) truck only had 45,000 miles on it so I took it to my local dealership for what I assumed would be a warranty job. I dealer service all my trucks while under warranty. Long story short I was told it was a fuel contamination issue which scared the walls of the hpfp throwing metal pieces into the injectors, fouling them.
I would need all new injectors, fuel rails etc. as well as new filter housings, fuel tank cleaning, etc. I had receipts for every drop of fuel put in the vehicle and fought all the way to through the dealership to Ford who sent out a rep and who denied the warranty work. Fortunately my insurance company covered the ordeal and all repairs were completed. I got the truck back and 2 weeks later the truck died on me again. I called the dealership back who supposedly warranted the repairs but there first words were there is no way it is their problem, they would look at it but I have to consent that if they find it is contamination again I am responsible for the repairs which we all know just to diagnose they have to remove the cab etc.
I of course lost my mind and told them this is there issue and there is no way in hell I am that unlucky that I received 2 bad tanks of fuel from 2 different high volume highway side fuel stations in the same 2 months. it is obvious they missed something or there is another issue that was not addressed. They claim there is no way they missed something. I am at a standstill.

Truck was dead- 2001 F250 V10... Has a starter relay (solinoid) behind battery... put a new relay in there- no go- cleaner terminals... then I put key in start and shorted the 2 terminals in the relay and she cranked right up. That would mean the starter is still good correct?? something in the ignition system?

I have a 2001 f350 v10 that has been giving me fits. has 88000 miles. cranks and starts when cold or fuel pressure is below 40 psi. SES light will flash when it stalls and fuel pressure goes from 30 while running to 40 and the fuel pump runs continuously when this happens and truck will not start. replaced crank sensor and fuel pump was changed about two months ago. if I relieve fuel pressure it will start and run for short time then stall and fuel pump stays on. all fuses are good. I am at a loss.

I've got a 2005 f350 with a 6.0 starts when it wants. I have checked the ficm and 48 volts when key is on and cranking! How do I know if my icp is bad? Some days it will start no problem but most days it will just crank over. When it does start i run it for a while shut it off and try to restart it and it wont!

I have a 2001 F-250 XLT 4x4 with V10. Truck will not start. No fuel pressure. My Haynes manual does not show ignition or fuel delivery wiring. I have found the relay box behind the radio/dash. I need a wiring diagram and info on which relay is the fuel pump relay. Want to know so I can jump relay to see if fuel pump is okay.
Truck had sat for a few weeks being ran very little, so had to jump start yesterday. Ran for about 15 min, the shut off, re-started and ran for 30 min. Truck sat for about 1.5 hours then would not start. Charged battery overnight and it is 100%.

Engine light and error code for tps occasionally comes on , then stays off a while. parts store said it was ok (shows full range) , but ford has an update for computer to fix. engine is v10 and parts store erased code and it hasnt come back. the only indication that something was wrong is the light coming on and once on the interstate at high speed , then the off ramp slow down, the engine seemed to want to stall as if engine not matching actual speed for a few seconds, then it was ok again. I was out of town and the mechanic that looked at it told me to go to Ford for an update. He tested the tps and said it was ok.

I have a new to me 2000 F250 7.3 diesel with automatic. Truck has 185K miles and tranny is starting to slip occasionally. Do these trucks come with a OEM tranny cooler or do I need to add or upgrade the OEM one. Someone also told that there is something called "bulletproofing" the tranny on these trucks. BTW, what would be a reasonable cost to have a two wheel drive auto tranny done on my truck?

I'm having multiple electrical problems and not sure if all related or not but they started at the same time.
1) Occasionally (getting more frequent) truck acts like its almost dead and wont start, but if i remote start it cranks right up
2) Radio doesn't shut off when I open the door, but if i close it and open again it does
3) phone staying connected to bluetooth but its acting up when trying use phone for music
Pretty sure there is more but I cant think of them now.

I have a 2005 F250 , 4.2 tdi diesel. I just bought the truck recently and still getting to know it.
I noticed recently that when I turn on the key, the vacuum pump starts running and does not go off. It seems to run continuously and will only shut off if I block the white outlet pipe with my finger. Is this normal or is the pump stuffed.

Suspect I have a bad fuel pump. I checked for power thru the Inertia Switch. When I first energize the ignition I receive 12v after a couple seconds it drops to 7v. Is this normal? I checked at the connector to pump module and see the same reading. I swapped fuel pump relay and same readings. Just want to makew sure I dont have some other issue before doing pump.
