Getting code 34 (MAF)--5 different mafs (2 know to be good) so I'm pretty sure it is not the maf. My ? is do any of the ignition module wires pertain to the maf circuit? Reason I ask is I had the block off to check for bad ends. 2 of them were pushed back into the plastic block. Repaired that thinking that was the problem. No change. Obviously I'm slow when it comes to electronics. Thanks
 
Lee,

The MAF only has 3 wires going to it. The black is a ground, the pink w/ black is 12 volts and the gray goes directly to the ecm. I guess you could verify 12 volts between the pink and black wires and check continuity for the gray from the sensor to the ecm.
 
Make sure car didnt have a FASt in it as the FAST ties the three bar and the MAF signal together.

As above, confirm 12 volts and ground on the connector.
