Hi, I have a 93 850ci that has problems with the fuel pump and after I replaced it the engine runs for a few seconds and after that it turns off. It seems like some electric relays are shutting off but I am not sure what the exact problem is. If anyone could provide some insight it will be much appreciated.

Probably the fuel pump relay. Remove the relay & temporarily jump the terminals with wire & spade connector jumper. If motor runs ok, renew the relay.
