I have a 2006 ltr450. Got it believing that fuel injector was out because you could spray starting fluid into intake and it would fire off. Changed injector and still only starts on fluid. Thought maybe line was clogged. Put all new fuel lines on still same result. Changed pump and regulator with new thinking maybe not enough pressure to injector and still nothing.
Any ideas on what it could be??

Whats your fuel pressure?

Whats your fuel pressure?

That im not sure. When fuel line is disconnected from injector it does push fuel to injector. I didnt know if buying complete new regulator would help get pressure up or not. Ive never owned a fuel injected quad before this one
