MAF Issues

[TNRGreene]

I have zero across the log of: MAF PID on my LLY, it was .33lbs(off) jumped up to 5 something when started.
I also have zeros across the log of: MAF Sensor voltage PID on the LLY, LB7 PID not valid
Traced the wires and and rang out ok. Change MAF out already & same. Flashed new tune & same

Any Ideas?

Have you checked the return/ signal voltage manually with a volt meter while running ? about all I can think of at the moment.
