Hey all- long time lurker, first time poster here.
I am pulling my hair out trying to figure out why my wife's 2007 M6 isn't getting fuel. I recently bought this sled as-is (not running) from a friend who didn't feel like messing with it.
After a few days of screwing around, here's what I've discovered:
I have power from the stator (new, installed by me) to the ECU (orange wires). I found this to be true at the connection closest to the stator, as well as at the ECU connection.
I do not have power from the ECU to the fuel pump (black/red wires). I tested the wires very close to the ECU connection, and also at the pump itself. Nada.
When I apply power directly to the fuel pump, the pump and the sled both run. I ran this test form both connections- the one closest to the fuel pump, and at ECU connector.
The main wiring harness and its connectors look great. I pulled the seat and the taillight to inspect the common wear areas- all looks good. I can't find a short anywhere.
Is there anything else I need to check before taking an expensive gamble on a replacement ECU?
The only other electrical issue I can find on this snowmobile is that both low beam bulbs are blown. Could the blown bulbs related to the fuel pump not getting power?
I wish I knew somebody with an M6 so I could verify whether or not my ECU is bad, but I don't. The suspect ECU has no visual signs of damage or shorting.
