Well I am swapping relays on my 88 iroc. I tested the fuel pump and it is pulling in for sure. On the MAF power and burn off I checked the power and they are getting 12v from the right sources.

but it appears that the dk blue wire is not getting 12v which means burn off not pulling in (with new relay) It appears I am not getting voltage to the MAF

with the maf disconnected should I be able to se 12v at the red wire?

can I measure voltage form the pins underneath the MAF?

Also in tunerpro the airflow readings by default for my $32B bin appear to be in CFM? is this right, the definition in the ADS has no conversion? The values are coming at 2500-3000 but what? g/s volts?
