72 c10 LS6 can't keep running
 

Hey guys! I'm new to site an ls swap so bare with me. I have a 72 swb that I have installed an Ls6 with the entire harness, column, cluster and fuel. When I first set engine into truck I got it to run no problem. But now that I have hooked up trans, water, exhaust and grounds it only runs for bout 5 seconds. Once it runs and shuts off, it will not restart until I pull key and wait a minute.
I am able to pull up codes through vette cluster but there's a WHOLE BUNCH.

did u flash computer??? im pretty sure u need too remove security

I have done nothing but transplant Everything from the corvette to my truck. Do I need to buy a programer? I have swapped everything but 6 speed and abs. I have both fuse blocks with ignition and vats, column, cluster, water, fuel pump, cats etc. Don't understand why I need to flash???

VATS is still working

If it is not the VATS, it is another system specific to the vette called column lock. Make sure VATS and column lock are both programmed to off, I had this issue with one of my swaps when I used vette parts.

It did say column lock and to pull key and wait 10 seconds. Is there software I can download or buy to delete this, or do I have to take it somewhere?
