Engine Does Not Crank, Replaced Ignition Switch Housing

The customer states the engine does not crank.


Confirmed the customer’s complaint and found the engine did not crank. Noticed the ignition switch did not have resistance when turning the key nor did the switch have spring back when the key was turned to the start position. Used a multi-meter and verified voltage was not present at the starter solenoid when the ignition was switched to the start position. Disconnected the electrical portion of the ignition switch, manually turned the switch to the start position and found the engine started normally. Visually inspected the ignition key switch and the ignition switch housing and found the housing was cracked, which allowed the entire ignition key switch to rotate freely in the housing.

Replaced the ignition switch housing and verified the vehicle operated properly. The customer’s concern did not return.


  1. What wrench do you use for lugnuts? That looks cool! Is it this wrench

  2. I know your expertise on this. I must say we should have an online discussion on this. Writing only comments will close the discussion straight away! And will restrict the benefits from this information.
