If connecting 5 and 8 didn't have any affect, it's pointing to an ignition problem. Perhaps a coil or the Ignition Module (DIS).

Sounds like you'll need to pull the plenum to test and repair further.

With the plenum off you can test the ECM (-) outputs to the injectors. A couple of noid ("solonoid") lights will come in handy for this. A basic 12v test light will be needed to simulate a Crank Hi signal to spoof the Ignition Module and ECM.

Let us know when you have the plenum off.

I fully expected to pull the plenum again . Will keep you updated .
