According to my scanner, all my values are perfect but the truck isn't starting because there's no sync. The mechanic I took the truck to says his scanner says there's a crank sensor signal. I took a look at the wiring harness underneath the air box and on top of the valve cover on the drivers side but I didn't see anything wrong. Also the mini blade fuses under the dash all seem to be in working order. I had an issue with the truck losing sync while accelerating from a stop and not restarting until cool, until one day it just wouldnt start at all. Any ideas are welcome.

 

You also need the cam sensor to show before it will sync.
