Had a problem with my truck today, 99 blazer 5-speed, just replaced fuel pump cuase pump wasn't getting power and wouldn't start obviously, got finished with that, drove truck about 25 miles and it died, i tried to start it again and boom new fuel pump wouldn't turn on, wtf, after sitting there thinkin for a while, i decided to disconnect my battery, and hooked it back up and, for some odd reason my LEDs turned on, i got in my truck and imagine that the pump turned on and the truck started.....CLUELESS?
