I’ve been reading up on a problem for several days now without any luck, but wondered if I couldn’t ask for some advice.

I’ve got a 2012 rancher TRX420FE. I really only run it during hunting season and made the mistake of leaving some gas in it last season. My friend asked to borrow it last month and so we loaded it up. He called about half hour later and said that it sputtered dead and wouldn’t crank back up.

I went, picked it up and began going through it. I think I pulled my fuel pump first and realized that I had bad gas in the bottom of the housing and also had some small gray particulate stuff. Not as big as sand, more like a fine silt. I started messing with my fuel lines and came to pull my petcock valve. My petcock valve was eaten almost totally up. the diffuser tube(?) was green and corroded, and the frame of the screen running up the tube was still there, but none of the mesh was still there. Long story short, it looks like the ethanol trashed my petcock.

I purchased and installed a new fuel filter, a new petcock and evidently a new designed piece of housing for the fuel pump which I was told I needed. I threw everything back together, primed the pump and began trying to start with no luck. I checked my plug which didn’t look bad. I pulled my IACV and really don’t know exactly what I’m looking at. I replaced it with the groove correctly seated on the pin. I listened for the pump relays near the battery and they’re at least sounding like they’re engaging. I pulled the injector and watched it spray, or more like spurt. I put my hand over the fuel filter and it would try and fire off, but not really.

I believe I have air, fuel and fire, but am just not getting it to even try and fire off. It will crank for days. One of the things I don’t know is how that injector spray pattern should look and if that’s my problem. I get a couple of streams of concentrated fuel. Is that injection supposed to be more like a fine mist? or will it kinda spurt out? I changed my plug last night just to be sure and still no luck.

Any help would be great. It’s basically still a new machine. I’m not sure If I have 30 hours on it or more than 120 miles. I really hate taking it to the dealer so I wanted to check here first and see if anybody had any input.
