    I just swapped out a wiring harness from a 97 silverado with a 5.7 vortec on to a 98 chevy with a 5.0 vortec. I have everything working, but it won;t stay running. While I tun the ignition it will fire for a second, then will die when the key is released. It has been down for over a week, and I can't find the issue.

    i think this engine has a passlock system that will probably have to be bypassed
