Nothing like doing a PM and having the truck not work afterwards.. Hehehe.. Any suggestions?? Chopper hydraulics by the way

well as with any pm, if your a decent tech you would have blown the lift off with compressed air. if you did this then check your connections on sensors/components. one may have become disconnected as fixit hinted on.
I'd also double check the state of the battery, a low or poor condition battery can cause all sorts of issues that will run you in circles. I'm like fixit though, i'm banking on a loose wire somewhere.
Check your fuses also.. :)

let us know what u find.
