Default My car won't stay running.....Utec

Okay,
This thing is bugging me out. My car from one day to the next is hard to start. You start the thing, it starts and shuts off immediately!! I've done nothing to the maps at all. So I try to go to the 0% column of my fuel map on the first three rpm points and add 5% fuel. For reference I was at -4.6%. The car still turns on and shuts off. I'm running closed loop, sti pink injectors, walbro pump, IK22 spark plugs.

Any ideas?

Oh, and at one point yesterday as I was trying to start the car I noticed I had no tach on my "dashboard" section of my utec. ***, is going on.

you may not get a tach while the car is cranking.

do you have an obd2 scanner? clean your maf sensor for the hell of it. how old are the plugs? fuel filter? can you hear the walbro prime when you apply ignition?

When the engine is cold, it uses higher rpm ranges in the map then when it's warm to idle. Ie-Ya might have to adjust the first 5 rpm slots in the 0% column and not just the first 3.

peace

Update, I borrowed another MAS from a buddy of mine who has an Sti. Plugged it in and also cleared all codes. Turn the car on and.........VIOLA. Everything is running fine.
So I went to my local AUTOZONE and picked up a can of Electrical parts cleaner and sprayed the snot out of my MAS. When I went to re-install, I noticed a nick on the o-ring for the MAS. So, I re-install it but I need to get a new o-ring.

Thanks for the help,
Jose
