Issues like the injector connectors and coolant reservoir would be the same on a GMC Denali 3500, correct? Same part numbers as well? I'm going to look at a 2019 with 108k miles this Thursday and setting up orientation with Indiana transport. Thanks for the great content l, sir.
I just replaced my hp4 a week ago. Didn't replace any lines or injectors. 500 miles sinced replaced everything is good. Mine just suddenly lost pressure is why I replaced it
Does your truck have the tow rating tag in the door ? My 18 denali does not and it isn't in the manual and I've called several dealerships with no 100 percent sure answer?
Had 1 under warranty replaced at 70k. Next one i did at 240k with 2 injectors that went out. Wemt thru hell with the 2nd one bc they sent a bad one new out of the box. These denso pumps are wprse than the bosch. Chevy cant get this fuel system right
U da man👍🏻
You got you a shop of your own
Awesome job bro
Thank you!
Nice video
Thank you!
My 2017 hp4 failed at 541k miles. I replaced it, now 564k miles. Mine had lost pressure.
My HP4 on mine locked up, they flushed the system and drained tank, check fuel filter for metal
What was the mileage on your rig
260000
Thanks for the info mr frank.
Interested to see what you find!
Me too

Crazy
If you need a engine there is a place in Hicksville Ohio that specializes in duramax engines and rebuildable trucks all models
Your theory sounds good, however I'd want to take that pump apart to see what's up?

Hope somebody watches this and knows what the heck's going on
Think I'm going to be able to pull pump today. Hopefully I'll see something

Hydro lock?
Can you please help me find the best scanner for my l5p
Sounds like the gear that drives the HP4 pump is bad
People with common sense can do anything possible...!!!!
Being patient and a little stubborn helps too 😂
