Driving and shuttered, drove home and turn in driveway and was sitting there and it shook a little and shut down end of story, lol. Checked fuses relays and ASD switch no power at switch, no fuel, no pulse, no signal, and no spark. Also, checked grounds getting five volt ref at cam sensor. I have not checked signal at crank sensor thinking computer. Your thoughts please.

Hi and thanks for using 2CarPros. Com.

The first thing I would check is the electronic engine control relay (EEC). The EEC is located on the power distribution box under the hood of the truck. If it fails, it will shut down fuel, spark. Simply switch it with another relay in the box that has the same part number. I have attached pictures of the relay box and components. You are focusing on number 8.

Let me know if this helps.

Take care,
Joe
