Fuel pump getting weak?
Ive been a member here for at least 4 years and used to own a 98 Z28 that has recently been sold. I just picked up a 2002 Avalanche Z71. When I crank it after sitting for more than 20 minutes it doesnt want to start. Crank it again right away and she fires up and runs perfect. If I get out and get back in within 10 minutes it will start up first try. Not sure if the fuel pump is getting weak or if this is a different issue. Any advice would be welcome.

Just replaced the fuel pressure regulator and the same problem still exists. Should I just replace the check valve or just do the whole fuel pump module while Im at it?

I had the same problem, plus my fuel sensor was giving me bad readings. I did not feel like fixing the individual problem with the pump, so I just replaced the whole assembly. Everything is working great again.
