Default HELP!!!! Security System on '91 Vette

OK... here is the deal, my uncle owns a 91 vette, but he is not around anymore. The vehicle was vandalized on the interior... they took averything that they could... We have replaced everything including the entire steering column, and new ignition system, wherein the problem lies.

After installing everything, and I ensure you, it is installed correctly, the car will not start without being hotwired directly from the battery to the distributor. It has an MSD ignition system in it... we don't know where to go from here. We are just trying to get the car started and running the way it should before my Grandfather sells it. Once the vehicle is started after being hotwired, the security light flashes, and once the wire is removed, the vehicle shuts off. Does anyone know what would cause this? We were told that it had something to do with the security system, and there is a combination with the headlights to disable the security system, but we cannot figure it out.

HELP please!!!

Default Does it Crank?

If it cranks but doesn't light then it's not the VATS security system. VATS won't let it crank when it's engaged.

I don't know what it is... unless you hotwire it, the is no fire to the plugs, and no fuel getting into the system... does that help any?

It's likely not the VATS system since it cranks. VATS alarm triggered won't let the starter engage.

Since you replaced your steering column I would doublecheck the ingition wiring in there.

Do you see a solid Security light in the right side of the IP? If not its not the VATS.

A flashing Security light is normal before starting the car and normally turns off a few seconds after starting. Something else is going on.

The engine runs, so with the key in "ON" but the engine off, is there power to the ignition and fuel pump? Is there power in the "START" position?
