The ignition, also called the ignition module, sends a signal from the battery to the starter and starter solenoid on your 2001 Chevy S-10. You can quickly test the module by turning on the headlights. If the headlights do not dim when you turn the ignition key, the ignition module is defective, and your 2001 Chevy S-10 won't start until you replace it.
