Have you done the basics like checking your fuses?

Yes and they're all fine.

If the tach does not move it's likely crank sensor related.

Pull the starter, the crank sensor is behind it in the block (not cam sensor, it will start with a bad cam sensor).

1) make sure it's still plugged in
2) check for burnt wires, they go close to manifolds/headers
3) pull sensor and look for damage

If I were you and the wires all look good, I would put a new quality sensor in it. Good chance it fixes your problem, if not it's a good thing to have a spare of in case it does go out because the car will not run without it.

Would a bad crank sensor cause the car to shut off while driving and have no fuel and no spark?

Yes, it happened to me.

Mine came unplugged.

Another time the wire was grounding on the header tube during turns, so if I made left turns it would die.

Well i've been lazy about fixing the car. I'm going to replace the crank sensor tomorrow and hope that fixes this issue. If it does fix the problem, will the car fire up and run fine with the new crank sensor or do i have to do the case relearn that i've read about?

Changed the crank sensor and it didn't do anything. But when the car cranks over, the rpm's read 0 and the speedometer jumps up to 100 every once in a while. I have absolutely no god damn clue what is wrong with it....

What does the fuel pressure do? Jump and die, or
nothing at all?

Problem solved, car runs now. My timing tuner is plugged in-line with the crank sensor. Come to find out, the wires going to the timing tuner got melted inside the wire loom next to the header. I unplugged the timing tuner completely, plugged the crank sensor in not using the timing tuner and it fired right up....how did i overlook that so many times ...
