Help with maf sensor

[cannon12]

My mass air flow sensor is not recieving power. The maf sensor relay is new. Of the three wires going into the sensor, it is on an 85 chevy camaro with a 2.8L V6, the black wire is grounded, the brown/white smaller guage wire in the middle is showing 5.2 volts, and the thicker guage Orange wire shows nothing. Out of the four wires going into the relay, there are two thicker guage and two smaller guage and one of each shows at least 12 volts. Don't know where to go from here. Any help would be appreciated!!

if the orange/black wire coming out of the MAF relay is showing power and the orange/black wire coming out of the MAF sensor is not showing power, i would say you have a break in the wire.
