no maf signal

[Vatche]

Hi guys, so ive been in the process of upgrading shit on my car. i installed 550cc injectors z32 maf and power fc.

so earlier i was troubleshooting a problem with how my car was running really shitty.

i tested injectors first by unplugging one at a time and nothing changed.

then i pulled the fuel rail and on a paper towel all 4 injectors left same amount of fuel.

so then i assumed it was the maf, like always on my car.(maf wiring SUCKS)

the wires were mixed up (my fault) i bought a multi-meter and test light to do the job right.

tested and found 5v signal wire and 12v constant easily.

i rewired everything and now i get no signal to the signal wire.
(i didnt disconnect the battery because im a FOOL)

power fc also highlights the afrl as 0.0v.

it wasnt highlighted before.

so i was scared that maybe i fried my power fc....

so i put the stock ecu back on and still no signal at maf.

i opened up the power fc to double check and i didnt see anything unusual.

can someone tell me what i fried and what to do next?

im hoping there is a relay or fuse i can check. i checked many but dont know where to look.

i searched for hours and found nothing on this specific problem.

thanks guys
