First off, I want to thank anyone in advance for their help, secondly please realize im super new to BMW's and I may sound illiterate at times, because I am. But as far as my mechanical skill it is very proficient, considering I am only 20 and no one has ever taught me anything about cars. Now the problem: Car: (1992) 325i 4dr. The newer style body with the M50. Problem: Car will not start (Fuel pump doesn't even turn on when key is on) How it started: My car was running fine at first, kinda rough at times the acceleration was a little unstable. I figured it was some sort of clog in the fuel system, so i tried cleaning it with Lucas Injector Cleaner. It was working better when I drove it home parked it and it didn't work the next day (wouldn't fire.) "thanks moosehead" Things i've tried: I sprayed starting fluid in intake and car started up fine so i jumped to the conclusion of my fuel system. I changed the Fuel pump, Fuel filter, Fuel pump relay. Still nothing... I tried using the Peake Research scanner tool, but i keep getting a fault that says it cant read the fault codes (irony at its best)... So im stuck now. I heard that it could be some sensors like the Crankshaft and Crankcase position sensors? But I live in Hawaii so its hard to get parts so i'd rather just order everything it could be at once... ANY IDEAS?!?!?
