1998 GMC Sonoma Question: fuel pump
Answer #1Superbob June 02, 2011, 14:06Master
Did a lot of fuel run out of the line when it was disconnected for the pump? If so, then there's air in the line and you'll have to bleed it out at the fuel pressure test port. I'm assuming that the fuel pump is running when you're trying to start the engine. If not, check the power and ground at the pump for starters.
