Fuel Pressure Loss
Howdy folks,
I have a 2002 Chevy Silverado experiencing a loss of fuel pressure after the truck has been running for 20 minutes or more. Please note: I have already changed the fuel pump, fuel filter, relay and fuel pressure regulator. Once the truck has sat overnight, it will build pressure right away (around 55 psi) and but then as the truck runs for a bit, will not restart at all and the fuel pressure has declined to almost nothing (5 psi). What could be causing this catastrophic loss of pressure while the truck is running? When it is running, it runs fine. For the most part, idles fine as well. I am baffled. I thank you all in advance for any replies.
