Engine overheated and shut off, now cranks but no start

I recently had my car overheat it cut off on me going down the road. I coasted it to the house. Car will crank but will not start. I inspected the front of the engine realize I need another water pump. I purge the fuel rail did get fuel to it. I pulled the plugs did get a dry oil on the sparks. They are all new wires and plugs. Catalytic converter has been replaced also.I checked the spark at the coil I'm getting spark. I checked the oil filter it is clogged with black thick oil. My question is, can a clogged oil filter keep from my car turning over? Or What is my solution here? I have put a lot of money into my car 3800 t top. I don't want to sell it I want to fix it. I don't have anymore money to put into it besides the basics and can't afford a tow to a shop it is my only daily running vehicle I have. What could be the possibility of my car cranking but not turning over? I hope my engine is not seized, but I heard if it is doing something it's a good engine. It ran hot and I pulled the hood and I smelled some plastic burning under the hood. Also the car was backfiring before it shut off on me. Any Ideas?
