What's Left To Check???
I'm still having issues with my 2011 750 Brute and looking to see if anyone can point me in the correct direction. See original post above. Here is what I have done so far.
Replaced fuel pump & filter / strainer
Spark is good, will run if I dump fuel into throttle body
I was getting some goofy voltages from the injector ECU so I replaced it with new one.
Replaced both injectors.
Noticed I had a open wire somewhere in the wire harness so I replaced it.
Still no fuel through injectors despite seeing appropriate voltage at the injectors.
When I turn on the key, the fuel pump pressures up, I see voltage at injector for ~ 2 seconds, no fuel blockage, no codes. WTF?
Is there any sensor that would allow the fuel pump to run, the ECU to signal the injector to fire but not allow it to fire up?
One thing on the list to check is fuel pressure but it sure seems good. Had a very slight fuel rail misalignment on one test and was spraying fuel everywhere, oops.
Anybody have anything? I'm about emotionally spent on this thing.
