I have a 2.0L gsr turbo that after i had put new rings on it wont start. The car drove in fine on the Crome map i was running. Now if it does start, the throttle has to be held open to keep it running, then when you turn it off or it dies it wont restart. I have a strong spark on all 4 cylinders, I have 180 PSI compression across the board. And my fuel is at 40PSI. Timing is dead on also. i have tried other maps and none will work. Please any help will be great. sadly i dont have a wideband.
