chek exhaust system mufflers , catalytic convertor. When car is COLD take a rubber mallet and smack these items. Listen for the rattling noise. Hope this helps

Testimonial: "The info on my idle speed control was correct, it was broke beyond repair. Replacing it fixed it for a whole 20 minutes. After that I changed the EGR Valve and the Mass Air Flow Senser. Everything runs fine now -no stalling."
This truck is fuel injected, the problem sounds like a weak fuelpump, it runs when you pour gas into it until that gas runs out, the first thing is to test the fuel preasure, if the pump is weak it may run with gas poured into it but wont idle, also a common problem is the coolant temp sensor and the ground wires to thermostat housing bolt but i wont bet its the pump inside the fuel tank, if you put a fuel gauge on it there should be at least 55-61 psi if its a few pounds lower it can cause problems, you have everything else and it runs with gas poured so its a fuel problem check the preasure, theres a valve up top on the fuel line to connect a fuel gauge to it, start there hope this is helpful.
