Are there any fuses for the fuel pump?
Doesn’t seem like there are a lot of fuses that pertain to the fuel pump. From what I have found there is no fuel pump fuse, just the relay. The ecm fuse was fine and the other fuses under the rear cowl are for misc unrelated stuff (lights, etc..)
Is there an ECM signal to the fuel pump relay?
The fuel pump relay works as it should. I always have power to Pin 30. I believe the ECM tells the relay to work via the green/black wire to Pin 85.
