The coil pack has a single power wire coming from the ignition switch (fatter black wire). The coils ground thru the power transistor module, which has 4 power transistors, one for each coil and a fourth as a driver for the tach, engine ecu rpm signal. The power transistors are switched via the ecu to set timing. When the power transistor breaks the ground path of the coil, the coil fires two sparks to two cylinders. Each coil has a bleck with color stripe wire (stripes blue, red, and yellow) that is the ground to the power transistor for that coil. There is a 5pih connector on the PT assy, numbered 1-5 with the catch up. 1-3 are the PT control circuits that switch the PT's. 5 is the tach signal output, 4 is ground. 1-3 and probably 5 should show a pulsing dc signal, probably 5v on 1-3 and 12v on 5, when the engine is cranked. I'd check all the connectors at the PT, ecu, and coil pack for corroded or pushed out/bent pins on the relevant circuits.

Go to mitsubishilinks.com and download the factory service manual for the 92-95 models. The wiring diagram is on page 157 for the 24v 3.0 a/t. The manuals also have a complete troubleshooting tree for no spark and testing procedures.

Post back with results and we'll help you troubleshoot, but it's easier if you have acesss to the manual and diagrams.
