Hello All,
I got myself into a project with an MSU500 that I got after a dealership had done a teardown on part of the engine. The previous owner had been riding and it died. i was told the dealer said that whatever was wrong couldn't be fixed, parts not available. A bolt for the Starter Clutch had loosened and vibrated out destroying the Stator and shearing the Woodruff key. I have replaced all of that and put the motor back together. My problem now is I'm a Carb. guy never touched an EFI machine and I am getting no gas to the motor. I have confirmed that there is No gas getting to the cylinder, it fires with starting fluid. The fuel pump is working, i have pressure to the Injector and power to the Black and White lead on the Injector and the same on the Red and white lead to the ECM/ECU. I have been reading and trying to understand some of the troubleshooting steps that I've found. I also have done the test with the Injector pulled out and put in a container and tried, not even a drop of fuel comes out. I have also tried with a New Injector installed with the same results.
I know this is not a Simple system but any input, or suggestions would be greatly appreciated.
On a side note: This probably needs a new topic. but while i'm and this will sound foolish but.
Does anyone know where the Fuse Box is on a 2016 MSU500?? Believe me I've gone thru everything Under the hood. It is not in with or near the battery box as one manual says. Not one the firewall, inside out under the hood. I have spent hours working on both sides of the motor and Under it and I've not found it there. And after looking up a New Part for this I can't even find what are shown to be the correct Leads from the wiring harness to Plug into the unit.
I thank you All in advance for any suggestions or info that you might be able and willing to provide,
Robert
