Without reading every old post I recall that tudstuen has a "fat blue" spark .....can't ask for better than that so the distributor sounds OK to me.
The fuel pump works, the injectors circuits work according to testing with a noid light although the injectors themselves are still in question....but all six failing would seem pretty odd.
ECU, relays, and injector allast have all been swpped.
It "wants to start" when starting fluid is sprayed in, suggesting lack of fuel.....as the spary is a substitute for gasoline
The ignition load relay has nothing to do with fuel injection or spark. It just powers up a couple accessory circuits to protect the igntion switch from excessive load.
I'm stumped.

fat blue spark
ok dumb question. how do you tell a good blue spark, fat meaning a size .. I don't know if its fat according to what you guys would know. when ive done the plug test on metal the spark is about the size of a tooth pick in diameter or close to the size of the part of pug the spark comes from. is that fat? or good if not what then?

I happen to have a toothpick in front of me :-)
I'd say that "toothpick" size diameter is good enough.

I must admit I have not read through all 13 pages of this thread but what I have read begs me to ask the following question. I read that he has tried to start the car by spraying in ether or something similar into the inlet manifold and that the engine attempted to start.
Would I have been wrong to have expected that the engine should have fired up and ran for at least a second of two to burn this all off? The fact it did not, could that not suggest a problem within the air flow valve. Maybe the reed is damaged or the flap is not opening properly. Could there be a blockage in the intake system.
Sounds to me because you seemed to have already covered just about everything else, it has to be something really silly.
(I did not see anywhere where it was stated what the exact fule pressure was at the fuel rail. Only saw it stated that it was good which really does not mean anything. Has to be between 35-39 PSI. which right now does not really mean much if the engine will not fire properly on a fluid being introduced through the inlet manifold.)

Has the shop given you the compression figures for each cylinder ? Frankly if you don't have the skill, tools, money or garage facilities, it might be time to sell and withdraw, no shame in that at all. However, you might, before doing this, try taking off the cylinder head to investigate.
