Re: jays144

Welcome to CamaroZ28.com. Usually not a lot of tech help in the "New Member Intro" forum.

I'll move this thread to "LT1 Based Engine Tech" for you.

Sounds like you may have a problem with the ignition switch. When you say "no lights on the dash" do you mean you do not get all the warning lights coming on for a few seconds when you turn the key to "RUN", like you would normally get?

jays144 - Please keep responses responses in a single thread. I'll merge this response (post #6) with your existing thread.

Re: jays144

The PASS-Key (VATS) system includes a starter enable relay that has to engage to crank the starter. That relay gets its ground from the PASS-Key decoder module.

Starting schematic - 1993:

In later years, the relay is called the Theft Deterrent Relay (TDR). The decoder module is called the Theft Deterrent Module (TDM).

PASS-Key schematic - 1995:

You may have a faulty TDR (also called “starter enable relay" on a 1993).

Re: jays144

The security light should come on, then go out after a second or two. I would start by checking all of your fuses if you are seeing no lights what so ever on the dash. If all of the fuses are good, it sounds like the ignition switch.

Re: jays144

Did you change the switch on the top of the column under the dash, or the cylinder? It sounds like the cylinder; I would try the switch under the dash.
