89 Ranger dual spark plug input control code

1989 Ford Ranger 4 Cyl 2.3L, 5speed 4X2 Dual plug ignition

The induction side spark plugs are not firing at all at any time.
The engine runs continuously on the right side spark plugs.
My KOEO codes are:
33 - EGR Valve opening not detected
41 - No HEGO switch detected
88 - Loss of Dual Plug input Control
My Engine Running codes are:
98 - Hard Fault Present
88 - Loss of Dual Plug input Control

What I have accomplished so far:
New Plugs
New Wires
New ( both) coil packs
New DIS Ignition Module

Still the driver's side coil pack does not produce a spark

The quick connector harness wires that plug into the driver's side coil pack don't appear to have any electrical current flowing while the truck is running.

The hard fault code (98) is probably referring to code 88.

How can i troubleshoot further back to find the problem?

how hard was it to change the plugs? i am considering a 96 ranger for super cheap, but it needs lots of work.
i have been searching on this issue without much luck. i will continue my search and let you know if i find anything out.
