easiest way to check it to unplug it. it will set a check engine light, but if it runs better than the ICP is your issue

do you have access to a scan tool or AE, that can measure HPOP and duty cycle? if the LPOP is bad you will have a hard time filling the reservoir and that is easy to check. you can also try pulling the IPR and cleaning that and replacing the O rings. also dieselsite sells rebuilt IPRs for $75
