Frustrated GM owner
Okay here we go 2006 Envoy Denali
with a 5.3 runs for about 40 minutes
then shuts off I cannot start it again
until it cools down I've changed my fuel
pump, crank sensor, cam sensor, my
ECT sensor, my ignition switch, my map
sensor, all on top of a new
transmission, I'm really asking for
somebody to give me an answer on
what the heck is going on with this
vehicle.
