Have you pulled the coil wire to check for spark? If you have points, check them AND the condenser. Have you checked the coil/ ballast resistor? Are you getting battery on the ignition side of the ballast?

It's a mopar electronic ignition system .I've only checked the coil with a VOM,and tried a new ballast resistor.Do you pull the coil wire,start the car and check for spark? Thanks again
