problem: the 3 cylinders on the port side are not firing.
The coil packs are good (swapped with known good from starboard side).
Wires from terminal block to coil pack all ohm out good
No obvious broken wires

Go to CDI Electronics web site and download there troubleshooting guild. You will need a peak reading voltmeter or adapter to test outputs.
