I cannot start the BMW M3 engine?

mdvalue asked:


I bought a 98 BMW M3 which was not running. The previous owner told me it has electrical problem and indicated out one burn wire that connects from the relay box to the control module unit (computer box), I replaced new wire, but could not start the engine. Is there any problem with the control module unit (computer box)? or any thing else that makes the the engine won’t start? I also had the ignition and key replaced (if this is the problem, how can I fix it). Thank you for your advice.

    Dude, you are in for one expensive proposition. I am putting money on the fact that this “electrical problem” is not minor. I have a feeling that the ECM is fried. It is not a cheap part, and if I were you, haul that M3 to a BMW specialist- NOT DEALER, and have him look at it. BMW’s in general, are not an easy fix vehicle, and the M series are even more difficult.

    i dont the solution of this problem but i can share my problem if this can help. i have 1998 m3 evo convertible. it has a weak battery. when i came back from holiday the battery was dead. when i opened the doors through remote the alarm goes on. i have a separate ESW alarm. i turned the alarm off and tried to jump start the car. but the key didn’t start the car, although all the ignition lights are on. untill now i have been told to reprogram the the key.
