Cleaning the Fuel Injectors...?
Alrighty!!.
I got the gas tank pulled, emptied and cleaned.
I got a new fuel pump in place.
I flushed and backwashed the filter.
BUT....
No start...
Im getting air, Im getting spark and compression..... when I use a little starting fluid, it tried to start for a moment.
So, Im guessing the Fuel Injectors might be clogged.... all six??.
(which is possible thinking about it).
I had a quick look at one the other day and saw a white crusty substence (almost like calcium) around the inlet side.
So... I think its time to build a rig and make an attempt to clean and flush the injectors (can of carb and choke cleaner standing by).
Any other thoughts??

Sounds to me like you're on the right track.
I had roughly the same situation while trying to bring my '90 Sovereign back from the dead. My homemade rig got 4 of the injectors clean & functioning, but 2 were DOA.
Here's what I built with some wire, alligator clamps and a large generic horn button from the auto parts store.
I used extra wire length and the big button so I could activate it with my foot, figuring both hands would be busy with injectors, spray cleaner & etc.
Not too pretty or cutting edge, but it worked great!
Good luck ... let us know how it goes.

EDIT:
Oops ... almost forgot!
The injectors have full-time 12 volts, and are activated by the ground, so I put my button in the negative wire.

Or you can send them to houston to Fuel Injector Cleaning Service : Injector Cleaning Service : Injector Cleaning : Clogged injectors : InjectorRX.com and have them flow tested before and after. Cleaned. Basket screens and orings replaced all for about $18 each
Well... I grabbed some pics.
But Ill post em later. I got one more to take.
Pulling the injectors from the rail and intake the problem was obviouse.
Lots of gunk and calcium in the injectors.
So, Using a few wires fuel line and my trusty compressor I madea quick attept to backwash one.... FAIL!
A good soaking in cleaner, then a few smacks with a hammer and try again....
It took a little work but one at a time, I got them working.
The issue I found was that the injectors need more than just a few PSi to work. Luckily my compressor goes upto 120PSi, but I found that I can only hold the pipe on the injector to about 12PSi, then it wants to pop off. But that was enough to backwash, and clear them.
I strongly suggest wearing somekind of glasses while cleaning them though.... ;-P

Well, after some testing....
:-(
Fail....
While I did manage to clear out some of the crud, I cant get it clean enough to do more than dribble a little gas.
Looks like Im gonna have to spend the $$$ and get 6 new ones. Eek.

So today I started up my Jaguar.... :-)
I took my injectors off to a place to get cleaned.
Anyone in the tampa / florida area... I recomend BOOSTLAB.
Their web site is www.theboostlab.com
They got all 6 injectors working again. Unfortnnatly one of them had a damaged pin and wouldnt perform the same as the other 5. So they only charged me for 5 injectors.
So after that I cleaned out the fuel rail with some B12 and my air compressor. I managed to get all the rust out. Then installed a small clear performance filter on the fuel line before the rail so I could see when things were getting dirty, and also have a second filter between the fuel rail and pump.
