Intermittent Spark
I have a 91 Eldorado with the 4.9 motor. It cuts out randomly while driving and will not start back up. After towing it back to the house, it starts up a day or two later. I have checked the fuel system and it checks out. When it doesn't run, there is no spark at the plug. I have checked the coil, wiring, ignition module and hall sensor in the distributor and they check out. It seems that whenever I try to diagnose the ignition, the car starts and all the components are working correctly . Has anyone experienced this problem and found a solution?
