Great! I'll do a little ATF in the cylinders and see if I can hand crank it. Not sure if I have the gumption to do the timing belt myself. I have a receipt that it was changed about 1000 miles before the car went dormant, so I really hope it cranks. Then onto fuel, BUT, I think I'll have to drain the decade old gas before pressurizing or circulating any gas in the lines.

It being dry of coolant scares me a bit, I hope it didn't blow a head gasket and have coolant in one of the cylinders. Maybe before putting ATF in the cylinders see if you can get your hands on a boroscope and take a peek in there to ensure everything is OK.
Also pull off the upper timing belt covers and check condition of the belt and pulleys. Post pics if you can.

Sorry to say I have to use 2 heavy duty C-clamps, and a little bit of coaxing in the end because the lip was so thick, but eventually, it came off. The pads are totally frozen to the plates, but I think that's the least of my worries. Now back to the engine.

Looks like there might be a field mouse nest in the filter housing. Have a peek. They love to set up camp in there. Get the engine firing first, then see what that coolant issue is. If there was coolant in one of the cylinders it doesn't matter now. The damage was done a long time ago. I woul turn the engine over by hand for a couple of revolutions and then use the starter to spin it more. Only if the hand cranking feels normal. Do all this with the plugs out and some ATF in the cylinders. Without the plugs, the timing belt will not see much stress.

That looks like a bunch of fun! Agree on checking for mouse nests, it does look like something made a home in the airbox.
Looking at the engine bay, I'd pull the airbox off, use a rubber band and plastic to seal off the MAF entry, and give the engine bay a wash down with a PH-neutral cleaner (e.g. chemtech ct18) and a hose. Don't use a pressure washer - just a gentle stream of water and a long bristle brush (pressure washer will force water into places it shouldn't be).
Then remove and dry all the plug wires, and proceed with advice from earlier in the thread
Don't get carried away until you can get it to run!

Wow. Forget inspecting the timing belt, just repl it and the water pump. I don't know what you find in there, but it won't be good. If the belt breaks on first start up, you will bend valves for sure.
Also going to need to get some lube down in the cylinders. I prefer WD-40 but there's a lot of elixers that people like. Take the plugs out, and dose each cylinder well with some kind of lubricant, maybe PB Blaster. Then turn the engine around by hand from the front crank nut before using the starter. That thing could possibly be frozen. After that TB WP and cleaning.

What's point of putting a new timing belt and water pump on if you knownit was coolant issues and the engines could be junk? A good visual insoection of the belt is enough to see if it will hold up for firing.
