Alright so just two days ago I replaced a bad alternator in my '89 325i. That fixed my no-charging issue. I drove it around plenty between then and 2am this morning. When I went to start it again at noon, it just cranked and cranked and wouldn't fire up. Battery was fully charged.
I listened for the fuel pump but didn't hear it come on at all. Unless it's really quiet, I think that's the first place to start. I am waiting for my friend to give me my stethoscope back tonight so I can check the injectors, but for now I'd like to make sure the ignition system is in order. I have a multimeter but I've seldom used it. How can I check for spark? I tried putting a screwdriver in one of the spark plug boots to see if spark would jump from the screwdriver to the valve cover but I didn't see anything; perhaps the screwdriver or the valve cover weren't conductive enough but I'm not sure. I also looked at all the fuses and they seemed to be fine.
Any help is appreciated. This is my daily driver and I need it for school tomorrow so time is at a premium!
