Question about 2000 Chevrolet 3500
I am having a problem with my 2000 chevy 3500 dually. It has a 7.4 liter with auto trans. If the truck has been sitting for a while it will start and run fine, but if I stop and shut it off, it will not start back up unless I let it sit for a long time. I have pulled a spark plug when this happens to see if it is firing and it definitely has spark. I also sprayed starting fluid into the throttle body during one of these events to see if that would do anything. The truck tried to start when the starting fluid was sprayed. This lead me to believe that there was a fuel delievery problem....but where and why would it run fine until it is shut off? Any ideas or suggestions would be greatly appreciated.
Hello, i hope this helps, it sounds like an open relay (bad relay). try swithcing fuel pump relay with AC relay and retest..if no sucess, feel free to reply and ill try to E-DIAGNOSE it for ya...lol.......good luck, marty
