I don't know why you're chasing the ignition, when it's clearly a fuel (or lack thereof) issue. Did you check to make sure your injectors are firing, as I suggested earlier? You posted no follow up to that test.

How is it fuel issue if the coil tested bad the distributor cap was bad the pickup coil tested bad and I'm still not getting fire . I have the correct fuel pressure at the rail and the injectors tested ok? I don't get it

Fuel + spark = fire. If you're getting no spark, you never said so. But you must be getting something, since the engine fires up momentarily with starting fluid. You would get nothing if you had no spark.
I know you cleaned the injectors, but did you test them all to see that they are getting an electrical signal while cranking the engine over? They can be as clean as a whistle, but that does no good if they're not being told to open and close. I didn't see the follow up to that test, if you did it.

No power to injectors, does this mean:
no battery power through INJ fuse(s) to one wire on injector connector?
Other wire on injector connector has no control power from ECM -voltage goes high-low-high-low, etc, when cranking?
