Hopefully, you haven't done any lasting damage. First, the coolant temp sensor must be in contact with coolant for it to register properly. So, if you've lost your coolant due to a water pump leak, there's a very good chance that's why the guage didn't register hot. It sounds like you've lost compression from it getting so hot that it washed the cylinder walls of oil. You can remove the spark plugs and pour in a little oil in each cylinder (about .5
ounce per cyl), crank the engine over a few times, then perform a compression test. If you don't have a compression guage, put the plugs back in and see if it cranks over "more normally". If you are lucky, the compression will return by allowing the rings on the pistons to reseal with the added oil. And, if you're real lucky, it may start and run. Of course, it will smoke blue smoke until the oil that you put in burns off. Now, if all is good in the world, you can replace the water pump AND the thermostat and hope for the best. I'd fill it with just water in case you have blown your head gasket due to overheating, so you don't waste anti-freeze. Good luck.
