The pump is probably ok from the tank but the injector pump may have been damaged if the filter failed and allowed particulate to enter the pump also the injectors themselves maybe clogged best way to check the pump is with an oscilloscope (lab scope) check the amperage waveform with the lab scope and calculate the rpm , also check the fuel pressure from the pump with an appropriate fuel gauge

Dirty fuel filter, clogged injector(s) water in fuel, dirty air filter. try fuel additive to clean injectors and remove water. replace air filter, fuel filter. possible could be the injector pump, would have to do a pressure check on fuel rail.

Hello,
Absolutely, a dirty fuel filter could cause that. You may also check your air filter, a dirty air filter can cause a bad fuel/air mix ratio, which can have similar results to a dirty fuel filter.

I hope this helps you.

You can also try Lucas Fuel treatment -- it works with cleaning the injectors, but will not take care of the entire list above,. ie it won't clean a dirty fuel filter - that you'd have to replace.

It could be a dirty fuel filter. If the filter has been changed and it still shuts off, have the fuel pressure tested. Low fuel pressure will give the same symptoms of a dirty fuel filter.

the cause of your problem would be dirty injectors,and or dirty fuel filters on truck. check the filters and replace the fuel filters. also check your air filter . if it's dirty replace it as well. hope this will help!!!

Dirty fuel filter or faulty fuel pressure check valve which is located on your fuel pump sending unit. Try this test, turn the ignition on for 10 seconds (engine not running) then turn it off for 5 seconds and turn it on again then try to start the engine after 10 seconds. This will re-pressurize the fuel lines to start the engine, the fuel injectors need 62-65PSI to have them start the engine. Anything less then that and you'll have starting problem.
If it start's right up, then your ether have a fuel pressure check valve gone bad or a fuel leak at your fuel pressure regulator which is also common, but if your engine is still running 100% then i'll lean towards check valve or dirty fuel filter.

Start with the simple and replace the fuel filter, a dirty fuel filter will cause fuel restriction that may just be enough to the fuel pressure below 62PSI upon cold starts and a dirty fuel filter will cause the fuel pump to fail early in it's life.
