Hello, My name is ***** ***** I'll be helping you today with the concern on your pickup. Thanks aw well for your patience and for answering the questions above. My goal will be to keep this as simple as possible!

I'd like to begin with asking a couple questions: You mentioned above that the vehicle will not start when the PRNDL is not illuminated on the instrument panel, correct?

**This makes sense if we're having an input issue to the instrument cluster, since the engines computer uses that same signal to know if the truck is in Park or Neutral to allow starter engagement. **

With the key on, have you tried moving the shifter thru the gears to see if the dash indicators highlights the shifter position you're in?
