Something may have been wrong with that post?? We need to know more about the problem. Does it crank, have spark, fuel? T

Most GM vehicles that won't start unless they sit a few hours need an RPM sensor replaced. If your car has a distributor, replace the pickup and ignition module. If it is a DIS vehicle, it could be a DIS module or a crank sensor. If you have a scan tool post again or e-mail me and I will tell you what to look for on the datastream.
