This one is driving me nuts. :( Originally thought I had a bad fuel pump. Key on, fuel pump winds up to pressure system is the way it should work. It has been working fine until about 2 weeks ago. Now I get 12v down to the final fuel pump connector (in the tank). Great-after a few seconds, the system times out then the power is removed from the pump (I believe this is normal?) My meter shows I have the 12v. Now when I connect the fuel pump the 12v disappears! I finally just jumpered the pump to the battery and it runs fine.
My factory manual indicates that the power source for this is through the relay from the Engine Control Unit. Relay tests good. So I am down to the ECU.
Now can not find anything anywhere on the net that shows ECU for the 625i gator, but I have found a Relay Control Module (AM144734). Question 1, Is this the same thing? Question 2, has anyone else ran into this problem and how did they resolve it? Many Thanks
