No spark and i can only get 5V at the coil.
Please learn to crop and re-size your photos. 800 pixels is the default "max."
About 5V with key "in run" is about right
Some of that wiring is out and out ooogly. Here's a simplified diagram............
I only posted the "4 pin" ECU wiring because that is undoubtedly what you have. WHAT IS NOT SHOWN there is the brown bypass wire, which comes from the ignition switch, through the bulkhead, and to the coil+ side of the ballast. THIS IS the same as "points" wiring and is the ONLY supply of ignition voltage with the key held to "start."
USING THE KEY and with the key in "start" you should have a minimum of 10.5V at the coil+
Below is a bit more complete diagram for the 5 pin box. For 4 pin ECU / 2 pin resistor IGNORE the "left side" of the resistor and the far left green wire. You still need the bold blue wire going to the box
