I have an 03 4 door ls 4wd... The other day I was driving it with no problems. I stopped at the last store and when i was done the truck wouldn't start. It would crank but not turn over. I poured gas in the throttle body and it started right up but died once that fuel was burned off. I can hear the fuel pump working and the injectors are working. I changed the fuel filter and now it will turn over but sputters and dies. I try hitting the gas pedal to keep it running but it still dies. Any help would be appriciated... I don't know what to check next.

 

Next step is to perform the complete fuel pressure tests in the sticky at the top of this forum.

I replaced the fuel filter and now it starts but immediately sputters and dies... If I give it has it dies and back fires... It was coding p0118 and the ECT sensor was unplugged... I plugged it back in and no longer codes but still does the same thing.

 

check fuel pump actual pressure....

 

The pressure is low... The fuel pump works... New fuel filter... There is a gurgling noise from the back of the engine every time I turn the key off. What else could be causing the low pressure?

 

An update... The truck is running now... I ended up replacing the fuel pump... I'm not sure what was wrong with it as it was pumping fuel at a good rate... But just an fyi if you remove the gas tank empty it before you put it back in.

 

Glad to hear you was successful. Good job!
