I put in a new fuel pump relay on my 84 318i. When I turn on the key to the power accessories mode the fuel pumps run constantly. I know with the older relays when you turned it on to power accessories the fuel pumps would run for just a few seconds. Any help greatly appreciated.

Hey there I'm having the same issue on the same car!
I replaced the 7 prong relay closest to front of car and now both pumps staying running when in the on position, and keeps the injectors all spraying at once. I'm chasing a rough start/idle, rich condition, where the spark plugs are wet with gas. Were you able to figure anything out? I am hoping the ecu isn't bad in my case.
