Sorry to hear you are having troubles. To get a meaningful response, please provide a bit more context. What kind of DSM is this? A picture of the engine bay is welcome. Given the age of these cars it could be so many different things, we need more information to help you narrow it down.

start with the what's missing list.
check spark- no spark work backwards into the ignition system.
check fuel- no fuel pressure? work backwards into why the fuel pump isnt working
have fuel pressure? check voltage and switching to injectors
if you have fuel, and spark, and timing (injector pulse) then move foreward to compression.
but the first three will likely lead you somewhere.
also what car do you have

I'm not getting spark, I'm not to sure what else I should check, I replaced my crankshaft and camshaft sensor as well including spark plugs, coils, and ignition module.

The connector in your first post is not the problem. For some models if was the factory reflash connector. It's always hanging freely.

im not getting any power to my ignition coils, what can this be?

 

[1990TSIAWDTALON]

Ignition switch, bad ground or anything in between to be honest. Power Transistor?
I don't see a profile for a vehicle so that would be helpful.
