I have a 1999 Chevy Blazer 2 dr / 4wd / 4.3 vortec with 90k miles. When the vehicle has sat overnight, or extended period during the day, it will crank for a long time then start. Mechanic tested the fuel pressure, and first thing in the AM, it read "0". He turned off the key, turned it back on and it read around "60" psi. After a few hours, did the same thing. The vehicle runs great otherwise, no spits, misfires, etc. Plenty of power and full throttle response. GM wants 654.00 for a new fuel pump. Is this the problem, or is this a regulator / relay or other problem. I have seen some posts where talks about the connector to the fuel pump getting hot giving different resistance readings, causing problems. thanx.
