It will run completely fine till it gets warmed up about 210 then the pump will shut off and won’t even prime till it gets cooled down again. I have no idea if it has a fuel pump control module or not.

I have a 08 Silverado ext cab 5.3L flex fuel truck. Trucks getting warm and shutting the fuel pump off. I’ve replaced pump, fuse, relay, ignition module and ecm/pcm still shutting the pump off anyone experiencing this?

I have a 2008 Silverado with 175k mikes on it. It’s a 5.3L flex fuel truck. It’s warming up and shutting the fuel pump off and won’t allow it to come back on till it cools back down. I have replaced the ecm/pcm, fuel pump, fuel pump relay, fuel pump fuse, and ignition module. Still does it soon as it warms up I can’t figure it out anyone else have this problem?
