I started pulling parts off of my new 91 318i M42 4 door parts car on Friday. Yesterday I swapped the coil pack first, my 318i still wouldn't start, (run a couple of seconds then die). Then I swapped the ECU, WOW!!! the difference was like night & day. It cranked right over after I swapped ECU's. I put the old one back in just to see if I had a bad conncection. no, it still ran like crap. Car runs great now. Is it common for ECU's to fail? I guess ECU's are a pretty pricey part. My $450 parts car that I drove away after buying it is already starting to pay for itself.
I pulled the tan interior (to include the carpet) out of the parts car last Friday. I'm going to put it in my 91 black 318i. My good 318i is black with black interior. I think it will look awesome, black with a tan interior.
