So I have e30 325is and recently when I start her up on a half tank or less the revs drop to under 1 and the car sputters and dies, but when I have a full tank she starts right up, the revs are normal and does not die and acts totally normal. I was thinking it could be a possible fuel pump issue but Im not too sure. Anyone have any idea of whats the issue? Thanks!

If you want to start throwing parts at it, then a fuel filter may not be a bad maintenance item to do. Checking fuel pressure with a gauge would be a proper first start though.
