1986 bmw 325es fuel pump relay issue, will not run with any other relay but will run with this one if the pump is jumpered.

Do you know if it is a ground or hot line? I would chase back wires and see where they go, maybe that pin is missing a ground.

Every port a pin goes in works, the original relay(multipurpose) won't work, I can't find a relay that will unless they keep sending me bad relays. The relay i installed works but you have to jump the 12v to the fuel pump pin which does keep the car running like it should. I just don't want to catch the car on fire due to the wire catching flame.

I cannot see the video but its not pumping fuel unless you jump a pin? maybe the tang is missing form the flywheel. or the sensor is bad at the bell housing?

[Boyd122]

Discussed that before, the sensor and the pin on the flywheel are both good. It has came down to relay's. I will try and Post video again if it will let me

[superj]

maybe a bad wire, like mentioned above?
