Will a bad ignition contact allow the starter to engage but prohibit spark? I've ran all the trouble shooting on the coil, ICM (tried two rebuilt ones, alt, ect. I'm going to recheck the grounds, but I'm running out of options. All I did was change the ICM and install a hard start relay. New starter, rebuilt alternator, new coil also. Ran a wire from Batt (+) to Coil (+) and Terminal 15 on ICM. All voltage 11.86V. Resistor is out of spec (2 ohm) but car ran with it as so before the ICM swap.
