Hi,

When you try starting it, is there any noise? Also, has the battery been tested?

Take a look at this link and see if anything helps:

Also, let me know if there is any clicking or any sounds when the key is turned to the start position.

Take care,

Joe

Hi,

Okay, we need to determine where the power is lost. I just want to confirm this is a 2010 3.6L V6. You indicated the engine as a 3.1L which was likely a typo.

If I am correct, question one is this. Have you checked the clutch safety switch at the top of the clutch pedal? Is it secure? Have you confirmed power to it when the key is in the start position and that power exits the switch?

If so and that is good, I need you to check for power at a few different fuses in the engine compartment fuse box. See pic 1. Check the highlighted fuses. Also, if the fuse is good, confirm there is power to and from it. Note: The primary focus here is to confirm power is present. Don't depend on the fuse is good.

Here is a link you may find helpful:

Let me know what you find. Also, if you do determine there is no power to any of the fuses, then check the ignition run relay. Remove it and switch it with a different one having the same part numbers and check if it changes things. If there isn't a different relay with the same part number, here is a link that explains how to test one as well as the circuit providing the power and ground to the relay.

Let me know what you find. If this all checks good, then we need to go straight to the starter circuit. Since you hear nothing, that is why I am starting at this point.

Take care and let me know what you find.

Joe
