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 |

Dave,
How do you have your MS realy board wired for the Fuel pump? Crash, So you're relying on the stock ECU rather than the MS-ECU for the Fuel pump control. I've pulled the stock ECU out completely and am relying on the MS relay board and ECU only. I guess I'lll have to go through the schematics again for both relay boards and see if the redundent relays aren't creating an open circuit some how. Thanks again, |
