Car Won't Start While Cranking

Mattax said
Since the starter relay is getting triggered, there must be power into the key switch and into the S2 wire.
If its an electrical problem it must be between the junction at the ballast resistor and the connection inside the key switch

S terminal and IGN 2 are seperate feeds.

Engine can crank but IGN 2 might not be making contact in the switch or along the IGN 2 path
