It shut off going down the road. I've replaced ignition coils, ignition control module, crank sensor, cam sensor, battery. Still no fire coming out coils. Got 12 volts going into ignition control module but none coming out. Earlier I took the coils off and ran test light from ground side battery to the prongs the coils sit on only three lit up. I picked the module off the plate it rests on and all six lit up the but with it sitting only three. What could cause that?

Hello,

I have included for you in the diagrams down below a diagnostic troubleshooting flowchart that will take you step by step in tracking down the problem with your ignition system. It will require you to use a multi-meter so I have included a link for you to go to down below if you are unfamiliar with how to use one:

Please go through the guide and get back to us with what you are able to find out please.

Thanks,
Alex
