HELP! car wont start after being parked for 15 minutes

[2mAn]

I am clueless whats going on. I literally havent had any problems with the swap since Ive been driving it everyday for the last month. Even earlier today, zero problems, nothing funny. Got off work at 5, drove home. Car sat for maybe 15 minutes after I got home and now it wont start. Its not turning over or anything, so I dont believe its engine related. Possibly the ignition switch? I checked the fuses and they were all good, also checked the grounds and battery cables and everything looked fine.

Where should I start?

I think theres something wrong with the car wiring or power getting IN the car. Tried to turn the running lights on to see if the lights on the cluster would turn on and nothing...

This is my one and only car, so Im trying to get it fixed tonight!!!!!!!!!!!!!!

Ground to the pan?

What voltage is the battery at? Sounds like your alternator is not charging, and you ran out of battery power.

Battery showed 12+V, I think its something with the fuseable link. My car was a 318 M10 car that got the battery moved to the back and the battery junction box was never installed so I need to see whats going on

edit: car is fixed now. I knew it was something stupid. CHECK YOUR GROUNDS!!! It was the ground in the trunk for the battery, not an OEM setup so I cleaned it up and everything is now back to normal.
