[QB93Z]

In the Service Manual Vol 2, look at page 8A-30-0, Starter and Charging System.


The Ignition Switch is shown at the top of the page. On the car, if you can, identify the Yellow wire from terminal "s" of the ignition switch connector 2.


Remove the connector and check for 12VDC on terminal "s" of the switch measured to battery negative, with the Ignition Switch in START.


If you have 12 volts on terminal "s", then we will need to trouble shoot the Starter Enable Relay circuit (ECM, CCM, VATS and Door locks etc)


If you do not have 12 volts at terminal "s" then check for 12 Volts at terminal "D" or "B", the input side of the ignition switch.


In START, if you have NO voltage at "s" with voltage at "D" or "B" then the ignition Switch is faulty.
