The truck shut off and won’t crank over, lights on dash but no engine light shows up. Also, changed starter hoping it was the issue and it was not!

Hi,

You indicated the dash lights turning on. What happens when you turn the key to the start position? Do you hear anything?

Also, have you confirmed the battery is fully charged?

Take a look through this link. Let me know if there is anything that is helpful. Also, let me know if you checked the battery's condition.

Take care,

I checked the battery and it had 12.4v so good and the only clicking when pushing the start button is just above the button in the dash, also the engine light is not on, and it was on!

Hi,

At this point, we really need to scan the can-bus to determine if there are diagnostic trouble codes stored in any of the modules.

CAN stands for controller area network. Basically, the different modules are tied together via a few wires. This type of scan will retrieve codes regardless of the module storing them.

Here is a link that explains how it's done:

Also, are there any aftermarket components plugged into the data link connector?

Let me know. There are a few different technical service bulletins related to a no-crank/no-start condition. However, I need to know if there are diagnostic codes stored to point you in the right direction. See pic below.

Let me know if that is something you can do or have done.

Joe

See pics below. Note: The pics are only a portion of the list. It appears there are multiple possible causes.
