After the car is hot and I park it to go into a store, I have problems restarting the engine. If I give it a bit of gas as the engine catches, there is no problem. If I miss the opportunity, the engine will crank as if flooded. It can take 5 minutes to get it started. The car runs strong with no issues. Any ideas? Thanks.

I put a gauge on the fuel rail and found inconsistent pressure. First swapped out the fuel relay with a Pep Boys part. Problem was fixed for a day or so. Problem returned. Threw a fuel pump in the car. Worked for a day or less. Went through another PB fuel relay as well. My son metered the relay box on the fender and voltages were fine. Ran a piece of wire in place of the relay and the fuel pump jumpped to life. Hmmmmmmmmm. It's got to be the relay. When to a GM dealer and bought a genuine GM relay. Bang, all is fine. For giggles we put the PB relay back in and back in the dumper we go. Put the GM relay back in and all is fine for over a week and 500 miles. That sucked, big time.
