Thinking my HPOP is bad. Need some help diagnosing.
First off the truck is a 2003 with 172k miles with probably the original HPOP. Many months ago the ICP started to leak oil so while replacing the ICP and harness I went ahead and did a few extra things. I replaced the O-ring on the top side of the HPOP between the dicharge tube and HPOP. I also replaced that entire tube with a new one from Ford since there was also an O-ring inside of that tube as well. I removed the IPR and there were a few flakes of metal on the screen which i cleaned off.
So recently my truck has been lagging badly past 1/4 throttle. Using my Edge CTS I finally noticed that when i'm past 1/4 throttle my ICP will not go past 1.0 no matter how far I press the pedal and the engine sounds VERY labored. When I quickly get off the pedal the ICP will flash really quick to around 4. Also I was running the truck a few days ago to try and check a few things out and once I tried to restart it it would not start, icp voltage only came up to .5 - .7. After it cooled down it finally would start.
I'm almost certain I need a new HPOP but I wanted to have any other ideas in case I am wrong, where else I could look.
Thanks for any help!
