    M50 has spark but no fuel!

    When I turn the key the fuel pump does not prime I replaced the fuel pump relay and it didn't fix it. I can jump the pins on the fuel relay and the car will start right up. Main relay and fuel pump relay have power but the pump wont run unless its jumped I'm also getting no power through fuse 11?

      Sounds like you need to re check your X20/C101 wiring.

              PO wired the car so pin 87 triggers the walbro fuel pump, however im getting low volatge at pin 87 of my fuel relay but correct voltage at all the other relay pins.
