Any pics .?
Shame , if you are close to DC we have a group of guys in NorthernVa that could be tempted to take a look at it. IF the shop thing doesn't work out let us know. (Calling dr Fraggle). ASCMA wants you!

@Viper > There are a group of us in the DC/MD/VA that have helped each other. Usually it involves inviting people to your garage and having beer, pizza, and some cool stories. Having tools helps

1. How soon do you want to have it running?
2. How much money do you have to spend and is price a consideration?
3. How far are you willing to move it?
Porsche dealers will cost you the most and likely have the least experienced techs for your MY.
Locals do coordinate get-to-gethers for wrenching but it can take time.
Curry's, Funktion and a few others can do the work but will cost you as well. Probubly close to dealer costs based on labor costs alone.
I am not familiar with Taylor but might be a great start.
Good luck!!

The first of MANY things will be the full timing belt waterpump all coolant hoses, caps rotors plug wire set and fuel hoses could easily be $4,000 or so. THEN they can work on getting it to be able to run which could be another bunch of hours and parts depending on what else died as it was parked.
Which is another big ??? the coolant stopped working 3-4 years into the "storage" and corrosion of the heads and head gaskets may have damaged the engine. Not too likely but a possibility.

Your independent Porsche mechanic that is competent with 928s will charge you about $95+ an hour for service. Take to a mechanic not competent with 928s, don't bother.
All my prices are from research and quotes I've been given in my area.
TB/WP for a dealer will be $3,000 alone, about $2,000-$2,500 for an independent shop. Need new cam gears? $400 a piece (you need two) if you source them. More if they do it. About $4,000+ for TB/WP/CG plus accessory belts, front seals and the other gears from an independent shop.
Intake refresh you will need, a shop will charge $1,500 if all goes well. An extra grand if everything is seized up inside which will take them longer to do. Oil change about $300 from a dealer, $250 from an independent shop or $45 at Wal-Mart and you provide the oil and filter and watch them do it. Or just the cost of parts if you do it at home which I recommend you do since it's so easy.
Rotors, caps and plug wires for an '86 will run you about $450-500. I spent about that for my set of Beru wires from 928MS and caps/rotors from Roger. The wires are the pricey ones really. New air filter about $35. A tune-up will cost you over $1,000 for an independent shop to do it.
Fuel hoses you can do yourself if you don't want that done with the intake refresh, the set will cost you a $100 from Roger. Probably need your injectors cleaned too, sending them in will be about $160+. New seals are part of the intake refresh for injectors. MAF rebuild about $300. New battery about $100 or so I think. New spark plugs, about $25. Valve cover refresh, about $220+ if you do it yourself assuming you have leaks. Over $1,000 in a shop. More if bolts break.
Ground cleaning and central fuse panel refresh, cost of new fuses and cleaner which should be about $30 all in all. +$50 if you Stabilant 22A it all as well. Relay replacement can be pricey depending on what relays, but most of them are cheapish.
You're looking at close to $10,000+ easy to get it to running reliable condition with all the deferred maintenance done. If you need to pull the motor, an extra $7,000+. Motor mounts, oil pan gasket, steering rack rebuild, transmission rebuild....driver side door won't open from the outside? It'll happen one day, trust me, that's $350 for a shop to do it or $55 and 3hrs of work if you do it. The list goes on.
Do the work yourself with friends and you substantially cut the cost. I bet you could get it running for under $5,000 IF you did all the labor. I spent $2,500 in a single shop visit already and I'm pretty much set on doing most everything myself from now on. Parts are "cheap", it's the labor that really kills you. I mean, labor always kills you but for a Porsche 928, it will strangle you to death, revive you then kill you again.
It's great to see another 1986 around the DMV area I'd be happy to cannibalize it 
It's impossible to find a passenger side air intake tube for our year amongst other things....

12 years? Wow!
I would recommend doing a few things before you try to start it. There are a few items that could be problematic if they are stuck. The water pump is one big one. If it's stuck you WILL break the timing belt very quickly and then you have a real mess on your hands. Also the cams and pistons walls are probably pretty dry by now and that initial start could score the cylinder walls and cam lobes pretty severely.
So, first you need replace water pump and the timing belt (drain and flush the cooling system while you're at it). Change the oil and filter also. Then pull the spark plugs and cam covers and pour oil on the cam lopes and chain and squirt some oil in each of the cylinders, probably an ounce or so. Once the timing belt is back on and you've oiled the cams and cylinders then turn the crank by hand three or four revolutions. If the engine turns freely, then with the fuel pump off (relay pulled), crank the engine with the starter motor until you see oil pressure on the gauge, probably a minute or so should do it.
At that point it is probably safe to try and start the engine with fuel. Cam covers back, new spark plugs and fuel pump relay back in. (obviously).
If you feel like your only option is to take it to a shop, have it towed there. Make sure the shop knows 928's and knows how to bring back a car that has been dormant for 12 years. Doubt many shops know how to do either, let alone both.
My $.02.
Good luck.

Have you tried anything at all? At the very least I would pull the plugs (Vacuum the area first to get all the crap out of the way), drop a little Marvels Mystery Oil in the cylinders, (like a tablespoon in each), and turn it over by hand. If you are really bold you can remove one of the timing belt covers to check the tracking (or just peep through the inspection hole on the top of them while 'HAND' turning the motor). Gives you an idea of how smooth its spinning and if the belt is tracking straight.
After 12 years I would definitely replace the timing belt, filters (fuel, oil air), fuel lines (get a kit from Roger): as a matter of fact call Roger and get the timing belt, filters, fuel line kit, intake refresh kit and call us we will come over and help you out.
You can save over 5k doing it yourself and get to learn your car so if (when) you have a problem you can just roll up your sleeves, put on your manly look, and tell the passenger 'I got this..'
If you have a garage that has been home to your car for 12 years, and you have a decent tool box you can get this going yourself. (not that Im against a shop trying to make a buck, I just think old cars like this do not get the attention they deserve in a profit driven shop environment..).
