I have recently had a problem with my e30, the fact that it will not crank. I just walked out to it after lunch and it was completely silent. All the electronics turned on like they were supposed to. I got the battery tested and recharged so that can't be the problem. I measured the voltage at the small black wire at the solenoid and got nothing. Traced that wire back to the ignition switch and tested it at the connector. Still no power when key is turned. When I tried to use the diagnostic connector by jumping the pins and shorting the solenoid directly, the relays would click but still no sound from the starter or solenoid. When the pons are jumped on the diag connector, I get about 11.8 volts going to the starter. I have cleaned the ground on the oil pan and on the shock tower. battery terminals too. Relays and fuses look good. I am stuck! What could be the problem?

It sounds like you have two separate problems--if the key doesn't provide power that is one issue, and the second issue is that your starter doesn't activate with 12v applied to it.
Can you walk through how the ignition circuit was tested? Forgive me for not being confident in that troubleshooting step. I find it hard to believe that your ignition switch and starter failed at the same time. Do you have 12V to the ignition circuit before the switch?'84 318i M10B18 147- Safari Beige

Where are you locate in Ky? I have an auto e30 sitting in the yard. If I can find time from work and fatherly responsibilities, I might be able to pull the starter and try to help diagnose?
I like to be familiar with the e30s across Ky/Tn... That way I know what I'm buying in the future.20% Accurate
Morty: Well Summer maybe people that create things aren’t concerned with your delicate sensibilities you know? Maybe the species that communicate with each other through a filter of your comfort are less evolved that the ones that just communicate? Maybe your problems are your own to deal with and maybe the public giving a shit about your feelings is a one way ticket to extinction.
