2012 apex hard start and missfire

[T-rav 27]

hey guys i got a 2012 apex xtx with mcx turbo and is hard to start lately it take like 4 times for sled to start it starts stalls and maybee on 4th 5 th try it stays running and when its idling seema to-have a missfire on cylinder 2 and sometimes #1 and when i go to give it some throttle it will-sometimes die out unless i really feather it slowly

i would start with checking the ground blocks/relays.

if that is all good, i would check the fuel pressure with a gauge as pump might be getting weak or the regulator is failing.
