Tried switching out the relays, no luck. The fuse box is relatively new, and that was the first thing i double checked, its good. Chassis grounds are good. Voltages are dead on. Air intake system is new.

After i got the pressure out of the pump that I got, I figured it wasn't something mechanical, and electrical instead.

Also tried disconnecting the negative terminal, letting it reset, and trying to start it after a few minutes.

Used to working on cars, but the electrical system on this car just utterly boggles me. I have a feeling this is going to turn into chasing a ton of wires.
