R34 RB25DET NEO, crank no start
I have some trouble with my R34 GTT,
Was running fine untill this morning when i had to move it out of the shop
It was very hessitant to start, then sputted on what i would guess was 3/4 cylinders, then shut shut off.
After that i am only getting crank, no start. It had a tendency to start on 5 every so often, but would kick the 6th in 10 seconds later. What am I looking at here? There is no sputter to make me think it fires a single cylinder.
Coils and plugs checked for spark for troubleshooting the "sometimes start on 5", and all seems good. Am i looking at a MAF sensor defect?
Note; im running a piggyback ECU, as it is an auto. 660CC injectors, and about 390 BHP. I havent had it for long, but compression seems good.
Any suggestions on where to start troubleshooting? I have no tester for the piggyback unfortunately, so i cant pull codes.
Kind regards from Denmark

If you’ve got fuel and spark then assuming the engines ok it should run. Sounds like it may have flooded by the way you described it starting first time.
