2g injector will not fire....

[M1L3S]

2g injector not firing all 4 will not fire.

ive checked fuses(all the ones i know to check)

how do i check cam sensor is good?

car was given a base map, would that effect injector not firing?

car ran amazing until chip was reflashed.......

also did a compression test and it was fine, hasent started after that and chip reflash

Is it a stock CAS? If its 1g black or green top CAS I just unbolted it from my 2g and spun it. You should hear fuel pump running and injectors clicking. Make sure you disconnect coil pack. I had this issue and it was all 4 of my injectors clogged at same time from car sitting for over a year.
