No spark. 86 FC

I'm pretty stumped here and not sure what to do next. I've been reading through forums and service manual and can't seem to find the issue. I have no spark at all and my fuel injectors won't fire either. I performed the test on the coils where you test continuity across the point with screws and they are in spec of under 1ohm. I getting battery voltage to my coils and I tested my ignition condenser and that's good. From what I've tested my CAS is good as well. I see that there is a Black/yellow wire that they all share to the condenser and that wire seems fine as well. My main relay is good. My fuses are good. But I obviously have an issue somewhere that I can't find. Any insight or help would be amazing. Thanks in advance.

Sorry to know of your troubles. First thing is to make sure that your battery is fully charged. If it is weak, turning the engine won't start the car.

Have you tried a compression test with a strong battery?
Start at the 01 section of the FSM, troubleshooting guide.
Then to section 4 and 5 troubleshooting guide. The guide is very methodical and a "yes" "no" flow.
If you are good with making wire harnesses, make a trouble light and use the diagnostic connection.

I haven't used this particular guide but it should be helpful. Good Luck!!

My ignition coils are fine. I ended up finding a random kill switch to the spark plugs and now I have spark. I still don't have a fuel injector pulse though. fuel pump comes on but no injector pulse.
