Bro I am in the same boat as you. Ours fired up on its own the first few times. Then all of a sudden it wouldnt start anymore on its own. It needed starting fluid. Im wondering if CAS timing could be off? But why would it start and run on its own before and not now? Also if I use starting fluid to start her up she fires right up and then idles normal.

ok so for an update. i took the fuel injectors out and cleaned them and the rail put it back to gether no help checked the plugs there fine. sprayed starter fluid in each individual cylinder and it would fire. once and then nothing. ive also noticed that it seems like air is being pushed out of the intake? (i dont have any intercooler piping on right now. ive also tryed spraying starterr fluid in the intake and it almost seems like its backfiring. it actualy shot a flame out the intake the last time i tryed it so im really confused? could the timing be off?

Sounds like the timing is off. Also could be the CAS. Start with timing tho.
