Rocks in the HPOP screen? How did it get past the Pick-up in the pan? I'ts screened... coarse, but still a screen. then how did they get through the LP oil pump? If you have ever seen one apart, how a rock would get through it is beyond me???
My guess is the ICP sensor, and or IPR have more debris in them. I'd say to pull the wiring off the ICP sensor and try to start it, but the thought of it actually starting makes the hair on my neck stand up! Having just put my motor back in last weekend isn't helping this sensation either.
