Tx, my Trailmaster 300 will not start. The fuel pump kicks on but when you turn the key to start it does nothing. Please help troubleshoot, thx all.

Electric fuel pump? Key start? What are these things? Sounds like you have an ATV/UTV. This a go kart site, dude.

My fuel is gravity fed or mechanically pumped via engine vacuum, and starting? I use my arm. 💪
Sure keeps things simple. . . 😊

Sounds like it could be a spark issue. Narrow it down:
Got compression?
Got spark?
Got fuel?

Robert, read the post a few lines down by Highmarker that's titled "TrailMaster 300X-E won't start". This guy "itsid" has a lot of input about it, and likely is the most knowledgeable source on this forum.
