So this morning I was driving my brother to school when my O/D light starting blinking. So I pulled to the side and shut the car off. Then when I went to start it back up nothing. No cranking whatsoever. My dash lights light up and before I turned the car off she seemed 100% ok (besides the light). I did replace the intake manifold yesterday but I honestly can imagine how that would cause this. If it wasn't installed correctly I would still expect it to crank. Im thinking PCM Any thoughts?

The PCM shouldn't cause a no crank situation. Have you tried a jump start, different key, etc.?

Its been sitting on the trickle charger all day and its a p71. No Immobilizer in the key.

It may be the digital transmission switch.

I figured out my problem! A little while ago a was getting some serious misfires. So I pulled the o2s out and test drove it to see if it was the cats. I guess in the short time I ran the car it managed to melt this

So now I need a 50$ transmission range sensor lol. Oh well it could have been a lot worse!

That exhaust heat can melt things in a hurry. That's the switch I mentioned. They're even called a neutral switch. Glad you found it. Thanks for the update.
