Fuel pump HELP!!
 

Hey.. im new to 318.org and i have a 96' 318ti.

I have been having problems with my fuel pump and could use any insights.
It started last weekend out of nowhere my pump failed during mid-highway driving. Got it towed back home and havent figured out what the issue is after 2 nights of trying. Car trys to start and turnsover but no fuel. Pump doesnt even come on. I currently have made sure every fuse was good, just checked the fuel pump and ECM relay, i put direct power to the fuel pump and she started so i know its good.
Basically.. i am getting no power to the fuel pumps plug. I tested the relay port and i got 12V at my constant and then 12V to my 86 when i turn the key. I bridged a piece of wire from my 86 to my 87 and when i turn the key i get 12v to the pump (finally) BUT now.. when i put on a new relay i get nothing.

Any help would be usefull.
Thanks.:confused:

Do you have spark when cranking the car over? Could be your CPS sensor is bad. Unless the DME detects engine revolution it will not energize the fuel pump. Also have you checked every fuse? even the 5amp ones. Make sure all fuses are good or you might not even be turning on your DME with the unloader relay during cranking.

YOu could ohm out your CPS to see if its good.
