When starting my vehicle it automatically pulls to the right while sitting. It pulsates to the right when applying the brake at has hydro-boost.

Sounds like you have an issue with the power steering pump. Basically the power steering pump provides the pressure for the brake assist so the fact that is pulsing when sitting still is most likely related to the power steering pump because when you are sitting still, that is really the only thing operating.

Have you replaced any parts to this point?

Let's try the following. Turn the engine off and pump the brake pedal to discharge any assist. Then hold the brake down and start the engine. You should feel the pedal drop slightly and then it will start pushing back on you.

Let us know what it does and we can go from there. Thanks

Okay. Let's try the test I listed earlier because a faulty pump will cause odd issues like this.

Let us know what you find and we can go from there. Thanks
