i have a 99 thats doin the same thing, intermitently wont start in park but if i crank it down to 2nd or 1st then shove it back up to park itll turn over no problem also sometimes when i put it in park like if im parking at a store or something the mechanism that keeps the vehicle from rolling back too far doesn't engage and i'll start rolling back but the motor idles as if it is in park, go figure i guess got to adjust something. oh yeah and it wont drop into first anymore, somethings gotta be wore out, idk.
