Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. Can you tell me if you are using a voltage meter? Are there any warning lights illuminated on the dash when you try starting it?
I will be online at different times throughout the day. It sounds like the ignition switch might be failing. If you can access the rear of te ignition switch I can tell you how to test it.
With everything connected check the voltages at the back of the connector. Make sure that the red/white wire has battery voltage with the key off. Then turn the key to run and make sure that the other cored wires have battery voltage. If not replace the switch.
Does the IGN relay under the hood click when you try starting it? If it does please check the voltage at all of the fuses labelled BATT, IGN, and ECM under the hood
