    try this to bypass or reset the security system turn the key to the on position and wait 10 minutes... the security light should stop flashing... then turn the key off for 5 seconds and then restart the car. the problem is in the tumbler itself and to fix the problem you will need to replace the tumbler.
    if that doesn't work you will have to have the dealer reprogram it they program it through the obd2 plug

GMC Sierra or Chevy silverado ? Do you have a SECURITY light lit ?
The SECURITY indicator is on the instrument cluster. If the SECURITY indicator flashes or if the SECURITY indicator lights continuously during the vehicle operation, refer to Diagnostic System Check - Theft Deterrent . If there is a problem the vehicle will start an run for just a second or two . It disables the fuel injectors .

Yes it sounds like a security system problem. Does the new column have pass key? You are leaving the key on until the security light stops flashing? The light is flashing for 10 minutes?

I changed complete steering column on my 99 1500 chevy.due to worn ot ignition and the key finally stuck in start position, thought was easier to RR entire column rather than take to $100 a hr GM...

Sounds like you end up at the dealership after-all.They will need to change the vin number to match your truck or the security violation code will not go away.
