The general consensus is not to use starting fluid on diesels with glow plugs because it is too explosive.

The highest probability of problem on your car (in my opinion) is something to do with fuel supply. It can take a long time to start a car if left sitting for a long time - several minutes of cranking. And don't forget the starter has a duty cycle - you should crank for some conservative period of time and then let the starter cool for at least as much time.

If you have already cranked for several minutes with no result, then the next thing I would do is loosen one or two of the metal fuel supply lines at the injector and crank some more - checking for fuel leakage at these injectors. This confirms your fuel system is properly primed and fuel is being supplied to the injectors. If not yet primed, this tends to speed up the process because there is no resistance to the fuel flow.

If you get no fuel leakage at these injectors with the loose lines, then back up in the fuel supply system and start checking things earlier in the supply. Check the "spin-on" cannister fuel filter to make sure it has fuel in it. Check your primer pump to make sure it is not leaking. Check your pre-filter to make sure it is not clogged. Pull off the supply line coming from the tank to be sure fuel is beng supplied and the tank screen is not clogged.

It should be a process of elimination along these lines - good luck.

I know you touched the wire and said ouch. But these older engines have the series glow plugs. You must be able to say ouch on the resistance wire that is furthest toward the front. Any plug can be shorted out going forward from where you touched the resitance wire. Do you know why they stopped using the car? Can you ask them? hopefully all was well the last time they shut it off. Also plugging in the block heater may help a little in the first start as the warmer you get the engine the easier the start. Concentrate on the fuel delivery but think you should have got at least a cough with the starter fluid. But perhaps not. Also since your fuel is old I would at least fill the filter with new fuel just on the off chance the fuel is bad. In fact might be a good ideal to drain the present fuel and put fresh in anyways. Diesel fuel generally stores far better than gas but exceptions are known. Also rather than letting frustation set in if unable to find out why it is not starting do a compression check. The compression gauge and adapters are available as low as 9.95 at hudsons or 16.95 at harbour freight for a complete set at a distributor that is spreading across the states. Once you are sure you are getting fresh fuel a tow start with a standard transmission is sometimes good with an engine out of service for a long time. The automatic can be towed as well but more complicated and much higher speeds have to be obtained. Read the archives as well about this. Sometimes it is required. Anything is possible but the injectors being clogged is such a long shot as to not consider at this stage of trying to find out why it is not starting. Almost impossible in otherwords. You are cranking but did you do as the one post sugested make sure fuel is coming out when you loosen an injector line at the injector ? While cranking? You have to make sure you have that first. If so make sure you have fresh fuel as well going through the system.

I would not change the plugs on suspicion of maybe they are bad. Instead read the archives about series glow plugs and get hold of a cheap meter and check them. You might as well start learning about the car anyways. Thats what this site is also about. Plus you like many here may not appreciate the cost factor of using garages to repair things. Your first indication that the resitance wire was hot is a good sign and that all is probably well there. But not a certain test. The archives give you that. Also do not ignore the slight possibility of bad fuel. It does happen but not usually again.
