I own an '89 325i. It will run when it wants to. When it does run it may decide to just randomly shut off at any time, in gear, driving down the highway, it doesn't matter. There is always power at the coil. It just doesn't get to the spark plugs. The master relay has been replaced and meters out with in specs. The reference/pulse sensor tests out ok. I have replaced the Motronic EMC and that didn't do anything. One thing I have noticed is that when the car is going to start you can tell because when you turn the key the Check Engine light will come on with everything else. When it's not going to start, no check engine light. The plug wires or distributor have not been touched, but when the car starts it runs and idles fine. Any ideas would be much appriciated. I have been trying to nail this ghost for awhile now, and being stranded is getting old.
