90 Cherokee Intermittant Ign. Failure

[thecozmo65]

I have a MSD 6 series Offroad (blue) module part # 6470. About a month ago I began having problems where the car would just stop running. It would do it cold, hot, from a standing stard, while going down the road. I replaced the Crank sensor, the coil, the plugs, I even replaced the W/P wire connector with a deutsch MSD plug & connector, and finaly I replaced the jeep ignition module. Nothing fixed it untill I un pluged the MSD and returned it to factory configuration. Do you have any thoughts or remedys.

The MSD Off Road Ignition, PN 6470, is color coded Black, are you sure you do not have the MSD Marine Ignition, PN 6460? Based on what you have described, I would recommend sending in the unit to the MSD Customer Service department so that they can check the unit out for you. Be sure to include a letter that describes the problem that you are experiencing.
