So, I have an 87 325is. Recently, I went to go work on the passenger window regulator. I left the car just on accessory to test the window, and inadvertently drained the battery. I jumped it, and then the car wouldn't turn over. Thinking it was the battery, I took it into Auto Zone. They checked it and charged it, and it was fine. So I started to look at the pumps. Sure enough, the in-tank wasn't priming or working. I pulled it out, brought it inside and hooked a 9v battery up to it, and it worked. Searched around a bit, found out it could be the Crank Position Sensor. Now I just hooked in a brand new one, and it still won't turn over.
TL;DR: In tank fuel pump isn't working, although the pump is fine. Help?
