I have a 1985 bmw 745i that turns over but doesnt want to start. The in tank pump has been replaced, as it was dead, and I thought that would solve my problem. It has low volts to the connection for the pump and the pump wont prime with the key in position. I have checked the fuel pump relay and it seems to be fine. I'm not sure what im missing so I could use all the help I can get. Let me know any ideas you may have on the topic.

Thank you
