Start Enable Relay


This is the 2nd most common failed part of the VATS system. This is much easier to disable than the ignition switch.

Things you will need:

The Starter Relay is located behind the DIC (Driver Information Center) Panel. To remove this, you will need to remove a few dash panels.

Once you have obtained the part, simply unplug the old relay and plug the new one in.

Start the car to see if this took care of the problem.


Bypass Information


Bypass Information:

Disconnect the relay from the wiring harness. If the plastic piece it is mounted to is in the way, unscrew it and set it aside.

There should be 5 wires coming out of the harness. The color combinations are as follows:

Starter Enable Relay Wires

  Pin A Pin B Pin C Pin D Pin E
1986-1989 5 DK GRN/WHT .8 DK GRN 5 YEL --- 5 YEL

Note-1 Below: 90-91 information for reference only. Need to verify if correct.

Note2 Starter Enable Relay located in different location than 86-89

  Pin 5 Pin 4 Pin 3 Pin 2 Pin 1
1990-1991 5 YEL 5 YEL/BLK --- .5 BLK/YEL 5 YEL

Clip wire from Pin A ( DK GRN/WHT) and wire from Pin E (YEL) and wire them together. Leave some excess sticking out of the wiring harness in case you ever want to revert back to using the relay again.

I would prefer to have used a large butt connector and shrink wrap, but I made do with what I had on hand. Just make sure the connection is secured firmly and covered safely.

 

 

Your car should start right up now.
