2000 envoy
1 Answer
I have a 2000 envoy with a 4.3 I just recently changed the crank sensor on it because it was having problems starting. It did fine for a while now it's doing the same thing just turning over. I noticed that the security light is flashing and I checked the coil pack to see if it is firing which it is and it's getting gas to the carb does anybody know what could be wrong with it
