Man that does suck!!
OEM parts too, man that blows...
I would be pissed . Only 15k miles wtf...

Looks like the pump might have gotten something in it and destroyed itself...
Well, I guess you got 2 options now, either rebuild it or see if you can find a GSR shortblock for sale.

Sorry to hear this, after you said you saved up just to get the car and now this happens. If you are not comfortable doing the work yourself, getting a used block might be the best option. Maybe an LS/VTEC would be cheaper route...
