If you are asking how to do this, it is not easy, it is very complex and takes a long time. The big points: Drain the coolant, disconnect battery, take off the intake manifold, take of the exhaust manifold, remove the head, clean the head and check for warp and cracks, clean the block and remove all debris from cylinders, install gasket, put head back on, put manifolds back on, replace coolant, change oil, connect the battery. You may have issues with bolts that break or strip out the block, you should send the head in to be checked, the valves and springs should be checked and those seals replaced, you need special tools and reference materials.

If you have a clear view of that cylinder, look at that area in the dark to see if you can find any sign of sparking that would indicate a failure of the insulation on the wires or the coil.

You'll need a helper for this. Refill the reservoir.
**Keep the blazer in park with the E brake on.**
It might help if you raise the front end onto axle stands. Run the engine so the power steering is active. Get you helper to turn the steering from lock to lock, hard left to hard right and back again. Do this 2 or 3 times. While they do this have a look at all the pipe work you can see, WEAR SAFETY GOGGLES if your under the car. Working the steering will show where the system is leaking.

Is your code reader capable of reading U, C, and B codes? The speedometer doesn't get it's speed reading from the wheel sensors. It gets it from the transmission. Not shifting past 2nd gear means your transmission is in "limp in" mode. It prevents shifting to avoid further damage. I see a transmission repair shop in your future.

It sounds like a linkage in steering column or at transmission has come undone or broken. You should be able to see the arm that comes down from the steering column to the transmission if you crawl under with a light. That's could be an an easy fix, but getting in the steering column is best left to professionals. Hope that helps.

Start cheap, remove fuses #10 and #28 under the hood. Remove your throttle body and clean it (both sides) with a sensor safe spray like Seafoam. When clean, put the fuses back and and see how it does.

I believe your timing belt broke and destroyed your engine. Also your starter could be jammed
