Hi. Thanks for using JA! I will try and help you out.


When you turn the key to the on position, does the yellow check engine light come on?


Also, did it shut off on you one day while driving and would not start back? Or did it just not start one morning?

The truck shut off while driving. The orange engine light flashed and the truck shut off now there is no engine light. When you turn the key to the on position no KMS are displayed only dashes, however when the key is turned to the accessory position the KMs are displayed.


Thank you

Thanks for the information.

The check engine light should come on everytime the key is in the on position. If there are no codes, it will go off. If there are active codes, it will blink.

If your light is not coming on, you either have a failed engine ECM or there is no power to the ECM.

Please let me know if you need more help.
