I've searched, is this an easy fix? I did my radiator and secondary air pump myself would a psp be a lot more difficult?

 

difficult? Not considerably, I believe all that holds the PS pump in the car is two bolts to the accessory plate and the pressure and return hoses. However, it *is* an expensive part to replace, the cheapest reman is going to set you back $300+. Just make sure to gravity bleed the system before you start it, and then remove all the air by turning the wheel from left to right several times.
