Time to review what things you may have done since the last time
it ran ok.
There are still no codes set?
The starting circuits are all stock ?(no bypass of starter circuits)
Just making sure.

Have you had any of the connectors to the DIS off?
Did any of the wires get pinched when the plenum got put back in?
Without having a code set this could get difficult to isolate.
Focusing on the DIS would seem correct.
Find out if it's getting 12v.
You'll absolutely need the factory manual for this.
