I have a new 131 mile, less than one week Silverado Trail Boss 5.3l and the truck would not start.
Four tries with the key, a remote start attempt and just engine cranking.
Called On Star and asked to have it towed. Sat for about ten minutes and tried again.
This time it started but a check engine light was set.
I had it towed anyway. Dealer said the fuel pump module was bad but truck is running and they cleared the code.
GM agreed to replace the module.
Anyone else have a bad fuel pump module?
