ok so i can crank my truck and it will run for a few seconds then eventually idle down and die, someone told me i needed to adjust my timing, but how do i? please help
well damn....could be alot of things...but i would start with the fuel filter...if not could you have a vacum leak at the throttle body? iam not too sure about your years engine though but i know with the 96 sometimes the temp sensor will go bad and then will not run right till the truck is warm...you could check out FullSizechevy.com forums for more help....or moonlightmechanic.com...
id try and start simple, change ur fuel filter like someone already mentioned, u be surprised what kind of shit a dirty filter can cause. But man, i just cant say WTF would cause that for sure
