    1987 325es crank no start

    Hey guys I bought another guys project a few weeks ago and have been trying to figure out a crank no start problem. I think it’s related to a bad ground since I can’t find a ground near the right strut tower. The car will run on starter fluid if I jump the dme relay but won’t fire injectors. If anyone’s dealt with something similar, I would appreciate any suggestions. Also if someone could tell me where I should be grounding the dme, or where the right strut tower ground is supposed to go, I would appreciate it!

    there is a whole series of diagnostics to go through to solve for poor running and no start conditions. it's important they are done in the right order or you may miss the issue. the faq/diy subforum has them listed out.

    start here : M20B25 DME Diagnostics
    then have a look at this one : Engine Management Diagnostics

    those are i car specific but the e car should be similar enough for you to work it out. ​
