I would like to know if the standard GM warranty covers the pump,i would guess no.I have never had a pump go,my mechanic passed this on to me and i've done it on a fellow expeditors vanwith good results.With vehicles that have the pump in the tank and you know or suspect you have a fuel delivery issue,kick the fuel tank hard a couple times and it should unfreeze the pump.It took 5 kicks to get the guys van started and i really wanted him to do it, don't feel comfortable kicking other peoples trk and it help the owner focus there anger at the appropriate thing.My wrench does this to get vehicles in and move them around in his shop when it's a bad fuel pump.The longest he's let the run is less the 5 mins,he isn't into wasting fuel he has a pump or something to move the fuel in and out of the tank.The guy i helped didn't have a cell [this was a while ago pagers back then] never called to tell me how far he got,he was heading up i69n to M.I so he, and his plate said.This was at the FT Wayne trk stop before the corral and he did get onto i69 i watched him,so this may help get ya another 5 ft or 50 miles i don't know.
