1992 Z28 manual

When I start my car normally, the orange SECURITY light comes on for about 2 seconds, then turns off.
When the car doesn't want to start, the orange SECURITY light comes on and doesn't turn off, and nothing happens when I turn the key. No solenoid clicking, no starter turning, nothing.

Since I'm having so much trouble with the starter system, I've decided to bypass the setup entirely and rig the solenoid to a switch so that I can start the car with the key in the ON position.

I'm just worried that I'll be able to start the car but it may turn off on its own after some time or the engine will crank but not start.

Does anyone know how the factory security system in the car works?

 

That won't work because the computer won't fire the injectors when the security lite is on. The problem is usually in either the key or the contacts that sense the key pellet. You can permanently wire a resistorwith the same value as thethe one in the key to the sensor leads. You will still need a key but the security module will always think the right key is being used.

Hmm

It seems that someone has already done the bypass, as I can start the car without the resistor sensing assembly. I have a feeling the resistor was either poorly soldered or not soldered at all, as many of the spliced wires under the car have been simply tied together and corroded with age. You wouldn't happen to have a similar bypass design for a third gen would you? I'll have to find the resistor now, if its there.

Thanks
