Question about 1991 Ford F150

1 Answer

Truck sounds like it's out of fuel. It chugs while driving at low

Whe I travel from 0-35 mph, my truck starts to die like it's out of fuel. I have to press the accelerator a couple of times to keep it alive. I have replaced the fuel filter but nothing. I think it's the pump but don't know where it is located.

    I only use the front tank since the back one leaks. the front one is brand new.

    Now How do I remove the bed because I got underneath and I'm lost?

  • stormserpent Jun 25, 2009

    Well the bolts are on pretty tight and rusted. One of the bolts is near impossible to reach because of the front gas tank.

  • stormserpent Jun 25, 2009

    Well I guess I'm going to have to drop the tanks but the back one, the bolts are rusted on tight and I cant use a torch bc it still leaks.

The fuel pumps are in the tanks. you can drop the tanks or take the bed off. once you get to the top of the tank you use a hammer and a screwdriver to turn the 4 inch lockring and pull the pump/sending unit out . does it act like this on both tanks or just one?

    if the rear tank will hold any fuel i would see if the problem happens with the rear tank also since it has its own fuel pump. if it doesnt happen with the rear tank you will know it is the front fuel pump and you can just swap the 2 pumps and solve the problem. if this is the case it would be easier to remove the bolts that hold the bed on and raise one side of the bed to access the pumps than to drop both tanks.

    look at the floor of the bed and you will see the head of the boltsthen get under the truck and you will have to reach in the center of the c channels to find the nuts.

    ahh welcome to the world of older vehicles. i had to cut my bolts off with a torch. they dont always design things with repairs in mind. I can only tell you what needs to be done but i cant make rust go away or make more room unfotunately. good luck.

    if all else fails use a hacksaw but it will take a while.

2001 jeep Cherokee sport out of no where started sputtering and chugging, running rough and 10 mph was top speed go about 20 ft then die. Start up and same thing. Went about 1-2 miles like this.

to me, it sounds like fuel related problem.
Clogged fuel filter, bad (aged) fuel pump, or water in tank.

one thing I doubt is "Sputtering".
low fuel pressure don't do "Sputtering".

Had just put gas in the truck when fuel low light came on. Traveled about 30 miles and the truck started missing then chugging. Then stopped. It will turn over but won't stay started.

you may have picked up dirt from bottom of fuel tank. change fuel filter and see if this helps! if it solves the problem, just put in some injector cleaner in tank to keep system least 2 times a month, unless the dirt has reached the throttle body and messing it up. check fuel filter first. have a good day !!

1996 GMC Suburban will start, but shortly after, it will bog down and die. In drive gear, truck wont go over 25 mph. and when I brake, the truck dies.I have replaced the fuel pump already, but the problem...

Can you hear a hissing sound? by saying the engine dies when you apply the brake makes me think you may be loosing vacuum and the brake booster my be bad.This will make the engine stall.

Failure to restart after or during travel

If it is dying while driving, but not chugging to a stop, and if you happen to notice the dash lights dim before the event I would imagine it is the alternator. If it kind of chugged to a stop and will crank over but not start I would look at the fuel system/fuel pump. However, more information is needed and it could be a few other options. I would like to know if it dies while driving, if you have had the battery tested and the year/make/model of the car.

1973 dodge 318 truck starts and drives fine until 35-40 mph then dies

Sounds like a fuel supply problem. Does it pop through the carberator as it it is dying, like a lean back fire? If you drove it up a hill would it die before 35 or 40 mph? If the fuel demand excedes the fuel supply the engine will die, but would restart after cranking the engine for awhile. Possibly a plugged fuel filter, fuel line, rotten fuel hose, ( sucking air ) or tired fuel pump. Hope this helps.

You may have gotten some dirty or rusty gas. Try blowing out your new filter, and see if it's good again. Either that or water in the fuel. Driving with a plugged filter won't cause damage.
