This is the story of a BMW loverís journey ......

I consider myself an electrical moron, so I have to tell you, I was scared to start cutting and bridging wires. So, I cut the green wire #4 and capped off each end. I then cut wire #1 and #3 at the EWS module and spliced them together. I put the red label DME in the car. I turned the key and the dashboard lit up as usual, but the engine would not turn over. Remember me mentioning how the EWS was activated when I forgot to put the antenna ring back on the ignition tumbler when I replaced it? Well, I knew that the EWS was being activated because it was the exact same scenario. So, I also spliced wires #1 and #3 on the DME side as well. Again I tried to crank the car. This time the engine would turn over, but it still had no spark and would not crank. Now I was really ticked off and thinking that I had no chance of fixing this thing. So, I just put the wiring back to as it was from the factory and I put the silver label DME back in it with the intention of having it towed to my mechanic........

I hope this long winded dissertation has or will help someone who faces a no-start situation.

Best regards,
Given attecntion to what you mentioned about the cutting and splicing of wires #1 and #3....

I just had to switch a new(to me) DME into my 1996 328is, so I followed the video instructions and cut/capped the green wire of the EWS to disable it and now the car will turn over but will not crank. I then tried the original DME and the same thing it would turn over but not crank.......Did I miss something about splicing wires #1 and #3?

After reading this post, this is my TO DO LIST when I get off work this evening:
1-Retry new DME with it in compartment and properly grounded as mentioned previously in thread
2-If still no crank... trouble shoot if it is fuel or spark issue
3- If injector or spark issue return to EWS disable method(and hopefully hear something from this reply by then)

Thanks to Steve for this awesome thread/write-up, and thanks in advance to those who read/reply,
Best Regards,
