2017 Alterra 700 XT won’t start without sStarting fluid ideas?

[ArcticRider]

I'm having trouble with my 2017 Alterra 700 XT. It won't start unless I use starting fluid after sitting for a few months while I was away. I've drained and added fresh gas, the fuel pump is operational, and the injector sprays properly when tested outside the machine. It's still not firing on its own. I'm not sure what to check next. I would be grateful to hear from anyone who has encountered this or has reccommendations

Even if the injector sprays outside, it might not be firing under pressure, so check spark, injector pulse, and clean the throttle body too

If it only fires with starting fluid, even with good fuel and injector spray, I'd check fuel pressure next, pump might run but not build enough pressure to start.

I'm in the same boat as you, starts with some fluid and dies. It's something with the fuel system, definitely, just need to find out what

@Truckislife Welp. It sounds like we're chasing the same ghost. OP, I think you should double-check the fuel lines and regulator too, since sometimes a tiny blockage kills pressure even if the pump seems fine.
