Check rpm sensor and fuel pump relay.
Do the tests in link I provided in the other no start thread above.
Need to determine if you are getting rpm signal first.
Do the fuel pumps fire while cranking? Have a friend crank engine and put your hand on pump and see.
Take a good look at rpm sensor wiring from top of bell housing.

The pump may prime, but there will be no fuel pump operation during cranking without spark.

Ha! Let us start here.
YOU DID NOT ANSWER! ?????
What do you mean by this?
And I think this link needs to be stickied.... seems like there are lots of 1989+ RWD no start issues. DO YOUR READING AND DO YOUR TESTS!!!!! DO YOUR voltage and resistance tests at the ECU plug!!!!

Told ya to start there!
When you said you had voltage on both sides of fuse, I almost typed that you need to do a better test. It needs to pass more than just a 12v trickle. It needs to be completely clean and corrosion free.
That wire powers up the fuel injection relay, so if its dead, your computers and fuel pumps are dead too!
How did you find out fuse holder was bad? A visual the test can reveal it, or if you bothered doing any of the tests in the link, there is a section where it has you perform tests there at the relay plug to confirm proper current flow and function of the fuel injection relay.
