HPO Questions / help

Hi all, I'm just going to get straight to the question. I have the pump deadheaded with a guage, I just replaced the IPR and cannot get any high pressure, only able to see about 150 psi. I have seen threads where they say the hpop doesn't just go bad, so that leads me to believe it's something else. Please, any suggestions would be wonderful.

The IPR is the second new IPR I have tried. The origanal was one with the edge filter, then I bought the first new IPR from the dealership, but that one had no edge filter. I didn't know the difference beween the two, but as I found out more I went ahead and bought one with the edge filter. No difference. With the pump already deadheaded, its got to be the pump, IPR or IPR related, I just don't what else to do.

oh btw, I can only here the injectors clicking when the ICP is disconnected.
Wow, thats not what I wanted to hear. Is there any other way to confirm a bad pump? Does anybody make a rebuild kit?
