Hey all you Squirters,
I finally finished the new wiring harness for the ECU & relay board on my MS install. Did any of you have to bypass the stock Fuel pump relay to use the MS relay board's fuel pump relay? Initially for fuel pump control I ran the #19 wire from the white connector on the stock relay board to the MS ECU. Now that I'm using the MS relay board, my fuel pumps not coming on when connected to it. Fuse checks out, and if I run the single ground wire for the FP to engine ground instead of the MS relay board - FP runs fine. Any thoughts? TIA |

It just comes off the pin on the terminal strip. I don't remember the number. I hooked up the + and ground backwards at the pump one time and it didn't run. It's hard to see so that is easy to do. If that doesn't work check continuity on the relay board for the pump circuit. Check the relay by swapping it with the others. I that stuff but sometimes you have to do it. Dave |
