I had no reason to disconnect battery
in recent past,not even to switch ignition systems out ie,MSD to factory ,car started and ran,though was fixed,switched back to MSD,car wouldn't start,switched back to factory. Car wouldn't start. All in past 2 days. one possibility,connector to coil may have broken wire,inside insulation,continuity check would require scratching of insulation near connector. I was taking signel from connector to trigger MSD ignition.
Starter Relay is entirely different from Horn, Fuel Pump,and auto shutdown relay which are same.
switched horn with auto shutdown relay,car wouldn'start.
Also,dumped small amt. fuel into air intake,yesterday,but jeep showed no inclination to start.
My impression is an electrial contact problem
Can you rule out CPU since I recollect that the coil drivers are in the CPU circutery? thanks Guy
