Ok guys i nee to the forum but looking for a little help, was driving down the road and my truck shut off now it wont start up,changed the fuel pump, changed the fpdm, still nothing, could i be overlooking something

 

What kind of truck? Need some details, we can"t see it through the Internet.

Why did you change the fuel pump and FPDM without troubleshooting? Did you know for a fact that you had no fuel pressure? If so, did you check the inertia switch? Did you do any electrical testing?

If your idea of troubleshooting is to shotgun parts at it, it would be better if you just had it towed to a shop.

 

check the codes

 

Glc its a f150 Harley Davidson edition and i changed the fuel pump because i was told i needed one, i changed the fpdm because it was time corroded, yes i have pressed the inertia switch and no i havent gotten around to checking anything else was just checking to see if i could be lead in the right direction before doing that

 

i didnt have access to a cose reader at that time but i sure will thanks

 

We still don't know what year it is.

Details are important.

Sorry was at work, its a 2007

 

Install a test lamp at the inertia switch in the passenger side kick panel. You will need to make a VERY careful observation to see if the fuel pump circuit is loosing its power that causes the engine to stall vs the power being dropped because the engine stalled.

Once you KNOW which half of the circuit is at fault, it allows you to focus on the most likely suspects.

This, of course, presumes that you intend to troubleshoot the issue instead of guessing.

 

Do you know it doesn't have fuel pressure. When you have a problem the first thing you should do is get the codes read. That onboard computer is pretty smart.

 

Quite true, but there are a number of things that the computer cannot "see" or does not check, therefore, the computer will not be able to assist in the diagnosis.

Sometimes, a human brain and some test tools and techniques must be used.
