what exactly is the question ?

the Crank Sensor (CKP) is located on the bottom of the timing cover. If it was not connected or working the vehicle would not run.

Door pins are a common failure on that series of Blazer/S10's. Also, another point of contention that the door faces is a sticky latch. Basically, the door latch re-latches itself and when you shut the door into the catch, it slams into it and bounces off. An easy fix is a 3 part cocktail of brake parts cleaner. Open and shut the latch with a screw driver acting as the catch and your interior door handle a few times. P'Blaster, open and shut the door a few times with the screwdriver acting as the catch. Finally, a good shot of white lithium grease. Open and shut the door with a screwdriver as the catch several times. Once you feel it is un-stuck, actually close and open the door several times. If you notice the door rising every time it catches, you MUST replace the door pins (cheap fix). If the door still has issues, replace the door latch (and since you're in there, do some PM and replace the actuator as well).

have you checked out your starter and solenoid yet

It's possible, but then you have the possibility of it being sucked into the oil pump if the pick-up screen is damaged or missing.

Is this an analog or digital speedo? If analog, three possibilities come to mind: 1. broken speedo cable; 2. broken speedo head assembly: broken speedo drive gear in the transmission final drive/output shaft area. If digital, could be many things.

Need to change tires, if you don"t could be cause for a serious accident, when metal thread is sticking out, you are probably real close to having a blowout! You want to stick to manufacturers recommendation, for tire size!

You'll need to find out if you are missing spark or fuel to continue.
