Hello for some reason my truck cycles more than 15 minutes of driving?

 

Sounds like it could be the relay gone.

 

I don't quite understand that statement

 

Agreed, cab heater or intake grid heater?

 

well for some reason we were checking all the voltage to everything and somewhere in a place where ther is expose to be no voltage im having voltage? and also i have not wait to start light, until i reset my computer so then for the first 4 starts my wait to start light works like it should but most of the time i do not have a wait to start light.
