Dear Forum Gurus:
This one get me! I have a W124 E320
wagon - 95. I recently replace the spark plugs and the all the ignition coils since on was bad leading to rough idle and poor performance.
Yesterday the dam thing almost did not start. I had to crank it over a couple of times. It finally came on and worked fine.
Today it cracks off terrific but it will not come on. I check the spark on cylinder 3 and there is non.
What could go wrong? This is my daily driver and I need to get this fixed asap.
Visual inspection led to no conclusion.
I pulled the OVP relay and are confused on the labeling of the pins. They are label 1 - 9. I have battery on pin 1. If I turn the key I get battery on 5 but not on 2. Is it shot?
I was also trying to pull the codes from pin 8 and pin 14 but my LED lights up but does refuse to blink. I get error codes from pin 6 but I do not understand!
Could it be the fuel delivery? But there are no sensors which feed back onto the
ignition?
Thanks for a quick response this is stressful otherwise the
car is in good nick but I did not replace the wireing harness yet.. I don"t think that is the issue.. Can I at least verify it before I spend the money!
