Default Question on mass air flow sensor

Iíve done a 6.0 LS swap, computer has been flashed, harness has been made,truck is starting and running. It will run with mass air flow censor unhooked, but dies as soon as I plug it up. Any suggestions on what the problem could be?

I'm having similar issues on my C5Z, if I plug in MAF with the car running, it dies. Cranks once and shuts off, and then runs fine. It's ignoring the MAF to run off the MAP.
I just posted a thread regarding this issue, I'll post the link, but my MAF signal (yellow wire) is getting 9v instead of 5v.

Did you check voltage on the MAF wires, plugged in with ignition ON?
