Suburban :: 2003 - Truck Not Starting / Security Light Was Not Lit

I removed the cluster in my friends 2003 Suburban last week to send it in for repairs as the gear selector and backlights as they were not working. I used this company several times before and they do excellent work. When the cluster arrived back a few days later I installed it and the truck would not start. I made sure the battery wasn't ran down and that everything was connected and still nothing. I called the GM dealer and the service tech told me that the truck should run without the cluster plugged in. Tried it and still no luck.

I proceeded to do the passkey security relearn procedure even though the security light was not lit and nothing. I got on here yesterday and read a post of about possibly a bad connection in the steering column so I lifted the column up and down several times while trying to start the truck and got nothing. All of the lights come on and I hear the fuel pump prime but it does not attempt to start. I drove the truck in the garage the day I removed the cluster and it ran great.
