I hope I am in the correct section. If not I apologize. 99 Bonneville sat for a week. Would not start. Thought I was out of gas. Gas guage on empty. Put gas in and it ran fine. Next morning would not start. Car sat another eight hours. Started right up but would not keep running. Got spark for the moment. Changed fuel filter. Can hear fuel pump priming. Got lots of fuel out of line when I primed pump with fuel filter off. Put new fuel filter on. Now no spark on any coil. Changed ignition control module. Start and run fine in idle. Sputters when I try to put any load on it. Put new plug wires in. Still starts and idles fine. Sputters and very light back fire when I put any gas to it. Now got check engine light for the first time. Any suggestions.
