02 Avalanche. It starts and 2 seconds later it dies. Fuel

Customer Question

02 Avalanche. It starts and 2 seconds later it dies. Fuel pump is going on and there is power to it. ALso, nothing is working on the cluster other than check engine light (that I put in from a 2003 Avalanche) I had to replace the steering column and the column came with keys, so Im a little frustrated at this point
JA: Does the light stay on, or does it blink?
Customer: stays on
JA: What is the model of your '02 Chevy?
Customer: even when the key is out of the ignition 2002 Chevy Avalanche
JA: Are you fixing your Avalanche yourself? What have you tried so far?
Customer: I am yes. Nothing out of the ordinary. The old wireing had an antitheft device that I took out and connected the factory wires back together (under the hood one of the wires was for the fuel pump and the other is a grey wire thats grounded) not sure what that wire itself is used for other than that I have checked all fuses and have been trying to find a broken wire
JA: Anything else you want the mechanic to know before I connect you?
Customer: no thats about it

this problem started right after the column was replaced ?

Customer: replied 1 month ago.
Negative. The sterring column was broken when i bought it and the original key wouldnt work. So i just reppaced the column. I reprogramed the key to the computer, (the 30 min key reprogram) and still will not stay going.

I stand corrected. It started working after the reprogram

i am unclear did it start up fine with the new column ? did it ever start up for you before any work was done at all ?

are there any theft codes set in the ECM or the BCM ?
