2000 Pontiac Firebird, 3800 auto
So, I've been having a weird intermittent issue with my car. In short what is going on is I have been having an issue where the fuel pump will not fire after shutting down the car while it's warm after a reasonable amount of driving, and it will not restart until it cools down. I replaced the following parts: Crank sensor, cam sensor, fuel pump relay and fuse and the fuel pump and filter were changed by the previous owner before I bought the car (which was March this year, those parts were replaced a couple weeks before I bought the car). The parts I personally replaced were all with ACDelco parts. No trouble codes as well, which baffles me to a lesser extent. I'm at a loss as to what could be going on here, so that's why I'm giving here a shot in asking what's going on here. If anyone has any questions or wants more information let me know and I will answer everything to the best of my abilities. Thank you and I apologize if this is the wrong forum.
