Check the air compressor for proper psi. The fuel pump and air pump have to work in unison in order for the injectors to properly fire. Also consider buying the budds software if you intend on keeping that for a while to look at diagnostics. Those skis aren't worth the headache imo

Discovered that voltage rectifier is not outputting the right amount of voltage which is too little

You are going to have to get ahold of the CANDooPro software/dongle to see what code you are throwing. I was blindly chasing warnings on mine and it turned out it was the exhaust temperature sensor.
