Car Cranks But Won’t Start

Around two weeks ago I started having issues with my 02 Grand Prix, it was running fine a few days before it shit the bed.

Whenever I turn the key to the on position, the Oil pressure light, ABS light and brake light turn on. I try tuning it on, and it just cranks and cranks and cranks.

I checked Alternator, it’s doing its job charging the battery when the car is off and whenever it decides to work.

The battery is less than 2 months old, bought it brand new.

Oil was changed a month ago (I’ve been changing it for years with 0 issues).

What could the issue be? I’m at a loss.
