318iS won't start!!!! Help diagnose my car!

[M42Technik]

So my car wouldn't start a few weeks ago, and my friend helped me charge up my battery. That got the car running, and I replaced the battery with a new one that very same day. I am at college and I haven't driven the car since then. It has been about 3 weeks since then, and today I go to start my car.

Same problem. the car cranks, but the more I try, the less juice it seems to have. Anyone else have this problem? I really need to fix this problem very soon!

Anyone who is in the area and can help as well would be awesome. Thanks in advance.

You've got a short somewhere that is draining the battery. Measure the amps at the battery. Start pulling fuses, when the amps drop you've found your culprit.

Damn, that sucks. I'll check for that. This blows.

Hard.

Keep the diagnostic coming guys, anyone else run into this problem?

[The Fast One!]

dang sorry to hear about this dan. i agree with james though since it was a new battery and not used for 3 weeks.

want a short term fix? disconnect the battery or put a disconnect switch if you're going to be letting it sit for a while

I'll do that, but since when does a battery die out after three weeks?

I'll check into the amps thing.

[kowalski]

it does that when there is a short... or the battery is bad

Lots of e30s seem to have parasitic drains on the battery. Mine had one, put a new battery in it and never let it sit for over a week without running, and I've never had a problem.

I agree with the battery unhooking until you can figure out whats going on. If you want to catch up with me sometime I can throw the load tester on it, and read the amperage as well.
