Okay, so, my 1985 325e BMW has a serious problem and has had serious problems in the past... Here is a list of everything I've replaced:
-both fuel pumps, aux and in-tank
-all spark plugs and wires
-my distributor
-my starting solenoid
-all of my filters
-my obc (on board computer)
-battery
-ignition switch
-timing belt
-oil
-oxygen sensor
And here are other things you might need to know:
I have a spare motorolic control unit that i got from a pick and pull, both in-car and spare work just fine
After, and im NOT joking, about 10 hours of work over two days, I pulled my starter out and got it tested, it worked perfectly... wtf...
So, to my current problem...
I took my car to the movies with my girl, and as i started up i noticed that the car sugged and had difficulty trying to turn, so i figured a dead battery was the culprit, got my boost box out, hooked it up, and the sucker started no problem. In the 325e, the battery is in the trunk, so, I actually, and regrettably
left the booster on the battery and drove it home...
The car has not been the same since... Now, even to start it, I have to have a fully charged battery and a fully charged booster, even then I can hear the shaft rotate once, wait a second, rotate once, and wait until after about 10 seconds the car will start properly turning over and then start. When it starts it runs and idles perfectly fine with no problems until suddenly the engine stalls after about two miles, and then it wont crank even if i would have put a thousand volts through it...
So, I do believe i have an electrical problem somewhere in the car, and I do believe a serious one... the last time I tried to start it the freaking RIGHT SIDE PASSENGER SPEAKER STARTED BUZZING!! no the radio was not on... what the absolute ****, right?
I am literally at my wits end with this car, and I love the thing its my first car and I would love any feedback on what it might be... I'm only 17 so although I've worked on other cars and mine a bunch, my knowledge here is dimmed from my lack of experience... If there is anybody that could help it would be much appreciated Thank you!
