Thanks for that. There must be a way to trick it. Strange because when the issue was intermittent, there was no code. It would either not power on the pump, or suddenly shut down while cruising along. Never a code till the direct ground was added.

I think the problem might be physical, a connection issue with the wire going into the board. However, after i grounded the pump with a vampire clip and check engine happened. I cut the wire to the board hoping to solve the problem. So I'm thinking maybe clearing the code might be worth a shot.

Yeah, the dealer misdiagnosed the problem. New fuel pump assembly $949 (CND) with tax. Sold the working old one on ebay for $200. ECU repair? Can they be fixed?

But it seemed adding the ground caused the code. I don't have a diagnostic tool. Which one is best?

No, how to clear it? Disconnect battery?

Thanks everyone. All sorted out. The ground to the fuel pump is supposed to be provided by the ECU but it's broken. I supposed a direct ground to the brown-pink wire. It works but Check Engine is on the display. Anyone know how to get rid of check engine?

The ECG/ECU provides a ground fo the fuel pump. This is broken, the pump woudn't power on. I ran a direct ground to the brown pink wire as dealer recommended as a workaround. Works perfectly but Check Engine is flashing. I cut ground wire to ECU but same issue. How to get Check Engine to go...

Update: I reassembled the pump assembly with new connector and cleaned contacts on the pump itself. Filled it up. It went 300 yards and died. BRP dealer sold me an OEM pump assembly ($840 CDN plus tax). I installed the new pump assembly. Pump does not power up. :(

I'm not familiar with the components of the fuel pump assembly. Will remove and have a look. Any advise welcome.

Thanks but, it doesn't power up when the key is applied if gas is above a half tank. Low gas and it powers on when the key is applied.

The fuel pump doesn't power on if it's submerged in gas.

My 03 155 will not start if the fuel tank full. Fuel pump seems dead. Starts and runs fine if I drain fuel down to a third of a tank. What's happening?
