Below center console , behind the shifter and in front of the ECU. Did you check your CAS already?

found the relay.,thanks...it wasnt that i put in a 91 relay( hope its the same) would the CAS stop the voltage at the injector harness?

The ECU doesn't know when to fire the injectors or coils without the CAS. The CAS provides the ECU with the positional timing information.

The car will crank and not fire either if the ECU isn't working, so you need to know if the ECU is powering up. On 1G turbo cars the ECU will turn on the CEL for about 5 seconds when you first turn on the ignition, it will move the factory boost gauge to 0 and it will home the ISC when it powers up.
