I have a 1990 Camaro RS which had a computerized 305 TPI engine. The computerized engine has been replaced with a non-computerized engine but the computer remains. My question is, can and is, the computer still doing anything? I have no check engine light. Has my computer been turned off? My speedometer also does not work. I was thinking about removing some unused wires in the engine compartment. I have no intention of going back to a computerized engine in the future. What would you do if you were me? I really need my speedometer to work and clean up the engine compartment of the unused wires.

 

Does computer still have power?
Is the SES bulb in place and good?

In your car the computer " should" be operating the speedo ( if the computer is powered up and working )

In consideration of a future owner that might want EFI , don't cut anything , just unplug what can be disconnected and roll up and hide the rest

 

I have no idea if the computer has power. All dash bulbs are in working order. the only light that is on is the security light because the VATS system has been disabled.
