How much has this swap cost you so far?
howd you wire this into your 4.3L truck?
PCM wiring is severly different between both platforms.
not to mention 2 extra injectors.

If it fires for a few ds then dies, I wonder if you need to do a security relearn.
The VATS is shutting the injectors down because the PCM thinks U are stealing the truck.

Like PAULY said, you have to have the VATS turned off or it will never start. VATS= vehicle anti theft system. If you are using the factory 6.0 computer then you will need to send it off to have the vats turned off and have it tuned while you are at it. Or, you can have someone with a tech2 reprogram the computer to match the cluster.
