Might be worth looking into.

can you please tell me the location of IPR, ICP, HPOP ( what part is this)?

thanks

Anyways to help you out here. I try to take a step back and simplify things. These trucks really aren't that complicated, you just need to be able to look at it as a whole. Simple systems. Diagnose, test, repair.

P2284 is ICP circuit range/performance (a difference was detected between commanded and actual pressure) This already tells us a WHOLE lot!

P2288 Injection Control pressure to high

I'm guessing you don't have access to a scanner correct? Do you have an SCT by any chance? Or any buddies with access to a scanner? We really need some readings to make a good diagnosis here.

If you don't have a scanner, try this. Unplug your ICP sensor and try starting the truck again. It wont drive down the road like this, but it will start and idle. By unplugging it, the PCM reverts to some predetermined standard settings and will let it start and idle. See if it changes your starting at all.

We really need this thing hooked to a scanner. We need to see ICP desired vs ICP actual, and IPR duty cycle.

Your dealer sounds like they have no clue what they're doing and throwing parts at it based on what the computer is reading. Whoever is doing diagnostics is basically throwing darts in the dark here.

I understand and appreciate your frustrations with the dealer, but please keep swearing to a dull roar. This is a "family" forum. Thanks, and welcome to DB~! The dealers assesment of fuel pump was crap. They were throwing parts at a truck with your money basically.

truck is throwing code P2284 ICP low voltage performance

replaced ICP sensor, not connector and truck ran perfect for 10 miles, all power back then threw ICP code again.
Replaced and rewired connector, code went away drove slow but no injector stumbling, still low voltage no Power driving

ICP desired PSI and actual PSI are the same starting at idle about 500-600psi, the same the entire time 500-2500psi however does not reach above 25-2700 psi even when getting on the throttle.

FICM is showing dips in the relay voltage as per graph while idling and driving, main power remains at 48.00 to 48.50 volts but relays are at 13.50v and dip to 13.00 Volts both idk wing and driving, seems to be the same ICP drops voltage.

IPR% starts at 20% and climbs with the ICP PSI around 30% and maxes out at 55% highest when truck is driving with ICP 2000+ psi

the truck has performance SCT tune and is deleted. Fuel pump ok
ficm synchronization ok
undiagnosed slight oil leak from either engine or transmission but has oil at desired amount (me checking frequently)

any ideas?! I’m pulling the ficm and checking the IPR sensor screen today, have new ficm but could a bad ficm cause the ICP? Truck has not been to a dealer to update PCM in years but ran fine, has had FICM issues in the past.
