Welcome to the forum! So . . . that's a somewhat complicated question. I think if I was tackling this . . . (and I know others will have their own approach. This is just mine.)
- I'd first change the oil in the engine, and replace the fuel pump.
- Since your replacing the pump, take that time to swap out the ten year old gas in the tank. Look for any rust or crud while you're at it. Definitely replace the fuel filter, and be ready to replace it again shortly after you get it running.
- Disconnect the coil from the distributor, and spin the motor over until it builds oil pressure.
- Fire the motor up and let it warm up and just breathe for a bit. Don't give it the beans, just let it come up to temp and watch for any leaks, or cooling issues. The goal is to get it back to running without risk a head gasket or anything else that has spent a decade drying out.
- Then, I'd replace the transmission, and service the rear end.
- Probably go through the brakes, definitely flush out that old brake fluid.
- Wheel bearings? Might want to repack them.
- Your tires are going to need replaced. Even if they look good, rubber only has a limited life and they're going to be dried out.
The expensive part is going to be the trans. Keep an eye out for a good deal. 'Expensive' doesn't have to be terrible. The rest is really just general maintenance parts that you can find at your local parts place.
Also - pics would be helpful. And appreciate.
