Does any one know of any thing under a 1997 blazer 4x4,near the drive shaft area, that when disconnected will cause it to not start? I just got it off the jack stands from doin the drive shaft ujoints and for some reason it will crank but not fire up. I had no problems before i did the ujoints. I can hear the pump kickin on. I dont under stand what could of gone wrong with in the period of it being on jack stands for one day while doing the ujoins.
