How much would that run me to get fixed if I replaced the pressure regulator or even starter?

No it just clicks and makes this whirling sound from I believe in the area of the starter Not exactly sure what a pressure regulator does.

if the battery has a full charge on it and the starter is clicking when you try and crank it,then i would assume it's getting power and the starter is maybe bad.if you got a fuel pressure regulator code of some kind,that don't have anything to do with it cranking over the engine!you need a volt meter and a helper to check the starter.helper tries to crank the engine over with key in the cranking position,while you check for battery voltage on the small wire on the starter. if you have battery voltage,and the starter attempts to crank/spin the engine,but don't,then most likely the starter is bad.if no power is going to the starter while key is in the cranking position,then the ignition switch is bad.

Thanks Steve. I'm so freaking busy with work I really have no time. It's probably something so simple . I'm just gonna throw $ at it. Hopefully I hire a good mechanic

good luck with it.
