I am showing no power at the MAF sensor. At the sensor relay, I have the Brown wire showing hot at all times as it should. I have a black/white wire which is grounded, as it should. I have an Orange wire which is the input wire for the MAF sensor, which is not recieving power through the relay, and a black/purple wire which should be the signal wire from the ecm to close the relay and send power to the sensor. Which the key turned forward, the signal wire shows around 13 or so volts! So if the signal wire is signaling and the relay has the power going to it, why isn't the power going to the sensor. The relay is a new one. Any help would be greatly appreciated! You can email me directly at cannon12@suddenlink. Net.

This will sound silly, but take a small regular screwdriver and hold it by the blade and bang the MAF with the handle. If the car quits running, replace it. Those could test good or bad and still set a code. The wire burns in them and loses contact.
