Default Car won't crank

So about 3 weeks ago I had some issues which ended up being the sending unit on the fuel pump. I changed that bc it kept shorting like a relay connecter to the pump (black blue wires) all good after that. Bout a week and now car hasn't turned over. It started where it'd take a couple turns but it's gone to not turning over at all. I checked alternator starter battery and clutch safety switch. Ignition switch seems good. Starter relay was changed crank sensor changed. My buddy's 06 sti

It's not cranking, or it's cranking but not starting?

Sounds like not cranking. If so, alternator has no bearing on that.
What is battery voltage, should be about 12.5 or higher.
How old is the battery?
Do other electrical items work?
Do you have battery voltage to the small wire going to the starter when you try to crank?
Check battery cable connections at both ends, should be clean and tight.

Wellllll......that's a clue. If the ECU has no clue what the mechanical bits are doing, it won't know what to do fuel or spark.

Easy is to pull cam and crank sensor plugs, make sure they are clean and seated, put together, then try again.

Next time, post ALL relevant info, sorta shortens troubleshooting time.
Sigh.
