gc8 fires up then stalls
 

hey guys

i was driving along stopped at a traffic light and the car stalled. tried to start it back up but it would just fire up for 1 sec then stall

ive since tried to figure out whats wrong with it and replaced:

fuel pump
fuel press regulator
fuel filter
cam sensor
crank sensor

but still no luck:(
engine is forged with 272 cams running pfc and z32

anyone have any ideas what else it could be?
