I drove my '90 525 from DC to NY last night and everything was fine. After parking and trying to restart the car it wouldnt turn over. I had a mechanic take a quick look at it and he told me it was the crank sensor. Anyway I managed to find the part and it seems fairly easy to install however the positioning of it makes it difficult. Can anyone provide me with any information on replacing this part? Another thing I noticed is that on the plug end (the end on the right side of the engine if you were facing the car and between the engine and transmission) there are two plugs that feel identical. One in front of the other. The one that is closest to the front of the car leads to the crank sensor i believe, what is the other one for? on my car it is just a loose wire and it looks to have been cut or broken, can anyone tell me what this if for? I know this is fairly vague information but I honestly don't know too much about this stuff (still trying to learn) and I tried to describe it as well as I can right now. It's been a long day. If there is anything else that needs describing please let me know and I will try. Any information will be greatly appreciated im in a real bind right now as I am stuck in NY and need to be to work on Monday morning. It is very difficult to find a mechanic in NY on a sunday.
