What's are signs and symptoms of HPOP issues

I posted earlier, but still stumped. I found a video that sounded like my truck to a T. What are some things to look for in HPOP failure? I did notice when cranking the truck that it sounds normal for the first second or 2, and then the oil pressure gauge comes up like it always does, and that's when the starving/hyperventilating sound starts...

Just replaced mine, you probably have the same style pump i do, the symptoms i experienced were hard or prolonged starts, low power, seemed to worsen the more i tried to diagnose.

check ICP actual, ICP desired, IPR duty cycle, Got any codes? i had p2290 ICP Low w/ no check engine light

Mine will fire right up like a champ. It has the normal 2 second delay before the oil pressure gauge comes up. That's when it seems like its a little low on fuel? The exhaust pipe is what will catch you attention at idle. She usually sounds like a plane, but now she still has the nice whistle, but a fast, and noticeable "lope"? I have no CEL on, and trying to be the odd guy and save every penny.

Also, she appeared to have good power, but today when I went for a ride to see if it still made the sound at idle, she was not really sluggish, but a slight misfire sound? Black smoke, and steady stream of that. After a few minutes she acted like she had some manners in town.

I would highly suggest checking your FICM (Fuel Injection Control Module) voltage, if it anything less that 47.5 volts you more than likely have and issue. Also i would check your fuel pressure our at idle as well as going down the road. Low fuel pressure = destroyed injectors = $$$. If you have it checked now it could potentially save you thousands of dollars in the long run, good luck and keep us posted

Hasn't ruined mine either. Just a great opportunity to learn all about my truck and to do a very necessary cleanup. Not mud riding after all of this...or at least until all of my cuts, bruises, and blisters have faded! Guess that's what I get for removing my FORD front grill emblem with a Peterbilt one. My son says it pissed my truck off!!!
