Weird no spark problem
Car left me stranded New Years Eve with a no spark condition.
Now, the problem seems to be intermittent. I have the pulse coming to the ICM(I have a spare opti I turn real slow to test this) and 12 volts on A and D, as well as a ground on C. This is with the connector unplugged.
The weird part is that when I have spark coming off the coil wire(with ICM connector plugged in), I also have good voltage on pin B, but when the car dies and there is no spark, I hook up my spare opti and the signal is very weak on pin B. But ONLY with the connector plugged in. I can unplug it and the voltage is fine.
Intermittent problems SUCK!
Thanks in advance for any help!!
