this may be a stupid question but have you checked for a spark in all of your spark plugs? I only ask b/c you did not list that you changed them.

you changed the rotor but didn't change that distributor cap?

If you are getting a spark, and you have good fuel pressure, did you check to make sure your firing order is correct?

Was there any clean spots in the upper plenum?

Washed golden?

What fuel pressure are you seeing with the key set to on and the engine off?

NEVER ASSUME A NEW PART IS GOOD. Go ahead and throw more parts at it and some day and thousands of bucks latter you might guess right.
GET THE FUEL PRESSURE READING FIRST before you waist any more money

Smarter words have never been said.

Assumption is the mother of all automotive fuckups.
