Why doesn't it crank or start????

Almost sounds like the antenna ring (part of the anti theft system) is wearing out and not able to read it code in the key chip. It wraps around the ignition lock cylinder and communicates with the ecu to confirm code in key is correct before disabling the immobilizer to allow it to start

Or it could be a bad neutral safety switch. Try starting it in neutral. If that gets you going it's definitely the neutral safety switch. You might have to put the shifter through all the selections a couple of times, but if it starts after doing all that, replace the neutral safety switch. Hope that helps! Jim

Didn't even think of that, try Jim's idea first, it's faster and easier to diagnose. I just got done looking into a vehicle with the same issue that had everything checked out including the safety switch, both of their fobs and keys quit working and wound up looking into how the keys communicate with the computer, so my brain was stuck on that.

Also make sure the bolts that attach the shifter lever to the shifter linkage are tight, they like to loosen up over time and make it appear as if it's in park when it's not.

i change the ignition switch and it works have to pull the raido to get to it the switch comes with instuction how to set the safty part
