06 Sportsman 700 EFI - Bad Fuel Pump or ECU Going Out?
Was riding my wheeler for a couple hours. No problems. Later that afternoon, my son is riding for 5 minutes and it dies. We tow it back. We can get it to start but won't run. We can hear the fuel injectors run when we turn the key, but it still won't run much more than sputtering for 10 seconds or so. Let it sit till the next day, and it starts and runs as normal. Troubleshooting with a local mechanic where we were, he thought it is the fuel pump going out. I take it to my mechanic now that I'm home. I had a new fuel pump. He says he'll replace it but thinks it may be the ECU, rather than the fuel pump. If it was the ECU, would it even turn over?
I want to go riding out of town in a couple weeks but don't really have a way to ride locally to see if I can get it to duplicate the problem. Thoughts?
