first off, that rubber hose next to the downpipe is going to catch on fire.
second, the maf is way too close to the turbo
third, was the car running fine before you put that wiring harness in?
fourth, do i even need to ask if you've tested the maf?

Yes maf is fine tried stock and z32 and this isnt how the motor looks now this is an old pic but car was running good after a rebuild then it sat for 2 ½ years for gathering parts and so forth but now i have this problem of it starting and running but it shuts off after u give it any throttle

You can't just swap in a z32 mafs without having the engine re tuned for that mafs.

He used a enthalpy ecu, tuned for 550 injectors and z32 maf

So you swapped in a different chip into the ecu that's tuned for the stock mafs when you tried the stock mafs?

No vac leaks and tps and cas are normal im thinking it might be internal but everything has been covered on the outside
