You can use a voltmeter quickly test the ignition switch or ignition coil. When the ignition switch has been set to run, the voltmeter should show about 12.6, If the voltage falls below that, it indicates there's an open circuit within the system. This could be a battery, solenoid or the ignition coil.

Connect the electrical connector to ensure that it does not interfere with the test. Set the voltmeter in the resistance or continuity modes and connect one lead onto one of the terminals on the ignition key replacement cost switch.
