KatahGii Posted March 24, 2020 Share Posted March 24, 2020 Ok so I’ve been trying to figure out why my fuel pump isn’t getting power I tested my fuel pump and it it working. Now I’m moving on to testing each connected to see where the power is dropping. This is the connector under the flooring that goes to under the bed. It’s got 6 wires colored wires. Anyone know where I can find a pin out so I can test the wires to the fuel pump? Link to comment Share on other sites More sharing options...
Ωhm Posted March 24, 2020 Share Posted March 24, 2020 Fuel pump wire is orange. C158_F. Fuel pump voltage will time out (2-3 seconds) with KEY ON. Link to comment Share on other sites More sharing options...

I was just assuming there would a negative terminal on the connector. Link to comment Share on other sites More sharing options...

Ωhm Posted March 24, 2020 Share Posted March 24, 2020 You had to go and find that 1%. Good question. If C119_10 is orange use that. 88 Electrical manual will show C157_F as orange. Fuel pump. C157 should be the correct one. Link to comment Share on other sites More sharing options...
