I have an 88 blazer (full size) that will start and then die after idling for 2-3 minutes, sometimes less. We have changed everything we can think of. (fuel pump, fuel filter, ignition switch, relay switches, etc., etc., etc.) We've taken the fuel lines lose and blown them out. We've bought a new fuel tank, and changed the pump. Once I figure out what is wrong with this thing, I'll basically have a new truck...just 'bout everything has been replaced. Sounds like a fuel problem, and possibly the fuel pump, but it has been replaced??? Do you think the aftermarket pumps don't give enough umph to keep the injectors going? Help me please. I'm losing hair and sleep.

i had the same problem with mine when i first got it. my egr valve was stuck, so i shot some wd40 in it and moved it up and down. that was over a year ago and it hasen't caused any trouble since.
