It is the factory yellow injector I'm looking for. We did re-plug in the factory injector harness to remove the fuel controler as a possibility. The issue is still there. We have good fire (and changed plugs), good compression (120 per side), fuel is passing PTO in the rail to get to MAG side so we suspect fuel (pump or filter)is not the problem, and of course confirmed its not a controler issue.
But the sled will run like it has a dead plug. No fuel is getting to the PTO cylinder. I'm located in Fort Mac.
I have been in contact with someone with used yellow injectors. But not sure how long they will take to get here.
