OK guys and gal, My RZR shut off last weekend and found Fuel pump is not coming on so I removed it and tested by connecting 12vdc to terminals on pump and in runs fine (also bought new pump from AutoZone) so I am getting no power to pump. Replaced 14 dollar fuel relay along with EFI fuse with new one still no power to pump. Does the ECU also control the fuel pump operation? Could this be my problem all together, bad ECU. I removed it and there was no moisture in the plug or the ECU that was noticeable but I can hear something rattling inside the ECU case like something broke loose. Any help will be greatly appreciated.
OK opened ECU and found a pc of the circuit board broken loose (round pc seems to have been connected to lower corner of board) this cant be good and possible my problem, but again will the ECU being bad keep the fuel pump from coming on?
