I was about 45 miles from home today when we went in to a store for about 15 minutes. When we came out I tried to start truck and it cranked and did not start. I checked all the fuses. I have 20 psi to the cp3. I unhooked the mp8 and set the smarty back to stock. So I got it home and pushed it off the trailer and went to show my dad what it was doing and it started write up. I have 124,000 mile on the truck. Any ideas on what it was or what is going out?

 

Any codes?
