My Alterra 1000 XT doesn't start

[Truckislife]

I was busy these past few months with trips and some work I had, so the Alterra 1000 XT was sitting dormant and covered waiting to see the light of day. Yesterday I went to my garage to start it up and prepare it for an adventuyre I've been planning for a while but it wouldn't start. Checked the battery and it was fine. Before putting it to sleep, I drained the fuel and added fresh one, so I know both of those aren't the problem. What should I start checking?

Your injector might be all clogged and dirty, that's what. It might also be that the fuel pump is stuck because... months without any trips? Isn't it lonely? Shoot some starter fluid in there and see what will happen.

I did that and it started ran for a bit and died, so it's definitely something fuel related, now it's just a matter of tearing it down to figure it out. What should I test first?
