I have a 2003 impala with a 3.4 it cranks and is getting fuel but no spark. I replaced the ignition coils, Icm, spark plugs, the security light was reset, I pulled fuses and check relays and everything there is good. All the wires are getting power, the battery is good and fully charged, terminals and wire are clean and it still won't start. Any help is appreciated
