S14 Wont start I'm stumped

[MJenkins1101]

I've gone through as many pages of the search as Zilvia will allow, and I have not found my solution.

Everything was perfectly fine until about 2 weeks ago then out of nowhere it the issue started. The only thing that changed from when everything was working fine to now, is I got an alarm installed, but it worked fine with the alarm for several days as well.

When I turn the key to start everything goes off, as it typically would, but I hear one audible click then nothing. I have a video of me trying to crank it I will upload it tomorrow, so you can see what I mean.

Onto what I have done. I replaced the starter, replaced the ignition switch, replaced the battery, and replaced the battery ground.

It's a swapped car that never needed the clutch to be down to start.

Any ideas helpful tips or confirmation that I'm not crazy would be greatly appreciated. Thank you for your help in advance.

I think I should remove the alarm and go from there, but I did not install the alarm, and I don't want to mess anything up anymore than it is already.

EDIT: It is a KA-T.
