My 2002 f250 v10 gasser has been having an intermittent problem. It has left me stranded multiple times and i can't figure it out. After driving if i turn the truck off it will start and immediately sputter down and die and will not start after. Then after a while it will start when it feels like it. it will crank but not start. please help!

 

Fuel issue maybe? Clogged filter or dying fuel pump? Change the filter first - hopefully that will be a simple fix for you.

 

I think i would start with fuel.....

it sounds like after it heats up then it wont start. That may be electrical....

you haven’t informed us of what steps you have taken to check it out....

 

i had a mobile mechanic come check it out (obviously not a very good one), he told be to change out the ignition switch and lock cylinder. Obviously that didn't fix the problem. and then i couldn't reproduce the problem until today. Im an expert in fighting fire, kinda lack in mechanics but i love learning and enjoy doing the works my self. just need some guidance

 

Fuel, also check the Fuel lines as the move back from the fuel rails to the frame rails - heat could cause vapor lock.

 

You may have a valve for your fuel rail...if so you can purchase a Gage, very cheep...just screw it on start the truck and just watch the pressure.....
also you can leave it on forever.....this may be at least one place to start.....

this is will measure your fuel pressure to the injectors....f t drops below specs....this will indicate a fuel pump issue....of if it’s not up to specs it will indicate a clogged fuel filter. Or a bad pump.....

 

alrighty gents i will work on this the next couple days and get back to you with the results, thanks for pointing me in a directions.

 

Please do....I’m very Courious

 

First thing I would do is see what's up with the fuel pressure.
Harbor Freight has an adequate fuel pressure gauge, #62623, for $20 (less with coupon) and there should be a test port on the passenger side fuel rail to hook it to.

 

Very sound advice. I had a 2004 V10 that had the same symptoms. Fuel pumps, and your symptoms are well known by mechanics that see a lot of Fords. This happened twice in the life of the truck, once under basic warranty, and again at 65k miles. Each time a Motorcraft pump was installed, and both times the part number had been changed to reflect an upgraded pump to deal with this problem.

 

Awesome guys picking one up today!

 

just picked it up lol good call on the exact part number and price lol

 

I vote fuel pump as well. Let us know.

 

so, i hooked up the fuel pump test gauge and turned it to accessory and get no reading. i turn the truck on and it sits at 32 when i turn it off it drops to zero. is it supposed to hold pressure?

 

I think it is supposed to hold pressure for a while.
