did you check the fuel pressure? there is a sharder valve on the fuel rail to do this. i know you have to have a certain amount of pressure in order for it to run.i think on fuel injection its around 60 to 70 psi.and on throtle body is around 30 to50.psi. i also know if you run your truck low on fuel alot it will burn up the pump gas is what keeps pump cool. also you said you found a pluged filter witch over time will burn up the pump. hope this helps.

Chevy Trucks, Blazers, S10 pickup and the like will vapor lock ecspecially the 2000 models. Do not tighten the gas cap past 1 click. There is a tube that runs from the top of the tank down and this gets hot and collapses or burns in half. We just bought a reinforced rubber tube cut it to lengh and use it instead of part and it's worked grat for 2 years so far.

Try replacing the intank plug-in for the fuel pump. They have been known to go bad even though they look okay.
SOURCE: 2000 GMC 1500. where is the fuel pump relay. Also
Yes I do. There is a roll-over saftey switch on the vehicle. I don't know where it is,but it should tell you in your owners manual.
SOURCE: Engine runs extremely rough, seems to be fuel
Have you changed the plugs, if any are fouled out or if any are worn, it takes more to fire it under load and may be spark knocking because one of the plugs can't fire off all the gas and cause it to skip or idle rough.
