2014, ran great, about 500 miles on it, just put an rktek rev 2 kit in, 25 miles on that. It starts normal when it’s cold & idles the same as stock but once it’s been heated up & ran then it gets harder & harder to start. After a few minutes sitting it will start first pull but only idling around 1100 until I give a little gas then it’s back up idling at 1800. Throughout the day it got worse & if I left it sitting for 20-30 minutes then I have to give it some throttle to start it & then it will take 3-4 pulls giving it throttle & each time it will fire for a second then die. I disconnected the boondocker & there was no change to the starting when it’s hot. Has 120 compression on both. In hindsight I should have pulled the plugs when it wouldn’t start hot & seen if they were wet but it’s slmost like it’s not getting fuel? Any ideas?

Check the Tps on it.

I had a similar problem and changed my fuel filter and reeds. Problem solved.

Still stuck on this.
Had it out to a dealer to check tps, they said it was out & adjusted it.
Took it for a ride yesterday & problem is still there.
Its like it gets vapour locked or something, the longer I leave it after shutting it off, the harder it is to start. 1-2 minutes starts normal, 5 minutes a bit harder to start, 10-20 minutes is a struggle to start.

what happens when you hold the throttle open and try to start it? i know you said you unplugged the boony and tried it but was that after you already tried to start it hot? i had a few boxes that needed to be sent back because the programmed injector voltage was off. sent them back to Sam at boony for the update and they worked perfect after that.

un****ingreal.
Changed the fuel filter, checked the reeds & went out for a ride. Now it won’t even idle, on top of being hard as **** to start.
The throttle felt fine but I was looking around the throttle bodies, contemplating ghost riding it off a cliff & walking back to the truck, & I see there’s no throttle stop screw. Gone. Must have backed off before because it would still idle fine then fallen right out recently.
Havnt been able to find one yet to see if this solves my problem, must be an m4 screw? Dealership can’t order one & m6 is too big.
