car won't start
My son has a 1998 Grand Prix. It will crank and crank but won't turn over. The only code the computer throws out is the #3 plug. All plug wires and plugs have been changed. It was starting if the air idle control was unplugged and then plugged back after starting. That doesn't work anymore. The ignition coil was changed today. Won't start. The starter is fine, the fuel pump is fine. A new fuel filter was put on. It did this once before and the shop said it was flooded. Any ideas on what to do next. Runs great when it starts.
