1993 Geo Storm, needs repair, 386,000 miles! Original Owner!

Hello. I have owned this car since it left the showroom at the Chevrolet dealer. They added some cool options to it being the sunroof, poiler, and mag wheels, raphics, tc and it truly was in the showroom. It has a staggering 386,000 miles on it. You read that correctly being 386,000 miles. My goal was 400,000 but I didn't make it. It has good tires on it, nd lots of new parts as I was trying to fix the issue it had but was unsuccessful. It has a new fuel pump, istributor, uel filter, TPS, ap and rotor, lugs and wires, ntake pressure regulator. It would surge and not maintain proper throttle yet by changing all those parts and it still wouldn't run right. The last time I started it (04/2015) the main pulley broke which probably also altered the timing so now it will not run. The clutch is fairly new and has less than 12,000 miles on it. I would like to sell it to someone who either needs it for parts or possibly would want to fix it or change the engine out. I was very good at maintenance on this car which you can imagine helped it reach the incredible amount of miles it has on it. Clean title and again I want to clarify that I am the original owner. If I had extra money and was retired there is no chance that I would part with this car. I would love to restore it but I don't have the time and cannot sink anymore money into it. I was sure the fuel pump was the issue however it still surged and had power loss.
Thanks for your time.
Chris
