Hi All,
I recently installed an engine with carburetors on a 2056. I am trying to use the stock FI wire to power the pump. I read where you need to jumper a cable from pin 30 to 87 on the fuel pump relay. I did that but I am getting constant power to the pump when the key is turned off. Any tips on how to wire the pump so that it only turns on when the key is turned on? |
