notorious duraspark ign module symptoms...........test: MAKE SURE VEH. IN PARK!, turn key to run position, check for spark while jumping starter solenoid manually (screwdriver or jumper wire). ive replaced too many to count with same prob. spark at key to crank position but module failure in run position.........if you replace module make sure you buy one with same grommet color...........kjun

Does it quit right when you release the key from START? Will it run if you keep it in START? Ballast resistor wire. Replace with one for a 61-72 Mopar with Essex (not Prestolite) ignition.
