There is no Ignition fuse, only an injection fuse in the engine compartment fuse block and it's not required to get the ignition system working. The connector that Rocketman is referring to near the engine fuse block is C135, it has 3 wires. Yellow/blue for the tach signal to the instrument gauge, black/white supplies 12V to the ignition coil directly from the ignition switch, and a blue wire the feeds 12V from the Injection fuse to the main relay on the engine harness.
Seeing that you have 12V on the Black/white wire at the ignition coil, it doesn't look like connector C135 is the issue. You also said you have 12V on the black/white wire at the distributor too which means the ignition system should be powered up.
The next thing I would do is unplug the ignition coil and do an OHM reading across the primary winding, it should read around 2-3 ohms or less. After that, I would check for continuity of the yellow/blue wire between the distributor, ignition coil, and connector C135.
