Ok Strange Problem! My car was shutting off at random times finally wouldn’t start back up. It cranks but wouldn’t start. So I checked the Crankshaft Position Sensor it’s resistance was varying so installed new one.
The car still cranks but no start, checked coil no spark; so checked voltage to coil ... none! Remove leads to coil and got 9 volts a previous thread I read stated some only have 8 volt input to coil so I assume once I received 9 volts input that I was good. And most likely bad coil because with the wires screwed down I get 0 volts then. I want to check resistance on primary and secondary but cant find any specifications on what they should be. Its a 1987 325i 2.5 M20 built April 1987 with a Bosch Yellow Label TCI Coil. Any Help would be great, thanks in advance!
