My Ride: 2001 330xi
Need help with rough idle and stalling

Alright so the alternator on my 2001 330xi went out last week so I replaced it. After install I tried to start it and it would just turn over but never fire. I searched and read somewhere that if the battery is low it won't start so I charged the battery fully and it started up and then bogged down and died. After a few more tries got the same thing, fires up for a few seconds then dies. I found that if I give it gas after start up I could keep it running. The next day I tried it again and it idles rough but would run by itself. But if I rev the engine up to 3k or higher and let off it bogs down and dies when it gets back to idle. I researched some more and thought it might be the fuel pump since I have 170,000 on what seemed to be the original one. So I changed the fuel pump but it died not fix the problem. Still idles the same but dies if I rev it up and let off. I need help diagnosing this. I've searched but can't figure it out. I went back and retraced all my install steps for the alternator and don't see anything I left unplugged or disconnected. Any suggestion are appreciated. Thanks
