No power to coils when cranking

1991 NA, The car did not have the leading igniter when I bought it, installed that along with new plugs and wires. Coils aren't getting any power while cranking, any ideas?

Check the 'meter' fuse in the fuse box by your left foot in the car.

If you already checked all wiring and fuses, it can be a problem with crank angle sensor. ECU will just ignore cranking in that case.

i think you mean the 10A 'engine' fuse inside the cabin, which powers the ECU, which in turn turns on the main relay that powers the engine harness and coils. the 30A EGI fuse under the hood would also be one to check as well.

We're both wrong, it's a 15amp fuse and they're right next to each other. my cover has been missing since before I bought this car.
