05 f350, 6.0, have bulletproof erg cooler and oil cooler, head studs, and a mild tuner. other then that pretty stock.

starts fine when cold, on vacation driving fine, drive to the grocery store(15 mins away) shop, come out crank no start, AAA tow to a AAA certified shop, he replaces EGR valve and IPR sensor. ($1400) pick it up drive home all great for 3 days but never tried to start hot in those days cuz didn't know it was a hot start problem, just thought it was a starting issue, and it was starting now. day 4 drive it around, park for 10 mins, crank no start. leave over night, starts, drive home, shut off, crank no start. leave overnight, starts fine. took it back to the shop he says it needs a new hpop, wants $3500, or all new injectors for $5k... i told him to pound sand. now its throwing a code, he says it says hpop, i go home, scan myself it says icp low voltage (which is the part he already replaced)

go home, drink beer and watch hours of youtube....

next day start a formal complaint with AAA to refund my $1400 the mechanic stole from me...

bought a scangauge2,

cold: starts fine, i got ficm sync, ficm voltage is 48, ipr is between 15-85 starting, icp camp up i think to 800ish and truck started. icp gets up to about 3800 when driving hard, ipr gets to 83% when on it hard, floats all around the rest of the time, never below 15 or above 85.

come back home from test drive,

hot: got ficm sync, ficm volt is 48, ipr is in the right range, icp won't get above 350.

watch more youtube....

I'm thinking its the hpop stc fitting, disassemble truck, get hpop out, looks like i already got the new updated stc fitting, i guess the guys that bullet proofed my truck added that as one of the "since we are in here do you want us to do this too, it'll only be $xx.xx more dollars" and of course i said sure to all that stuff....so i already have a new stc fitting.

during all my youtube-ing, it sounds like the 05 hpops don't really fail, like ever. so before i throw a $500 hpop at it, is there a way to bench test the hpop? is there something else i should be looking at with those symptoms, and how to check for that something else? do the updated stc's ever go out?

thanks in advance.

Stolen is right. ...and not just because it didn't fix the issue.

I can't tell if the one part that he put in was the IPR valve or ICP sensor but - regardless - he charged you about $1100-$1200 to put two parts in that maybe - MAYBE - took him 15 minutes. Seriously. Now... I realize that he may have some "diagnosis" time, but he sure-as-shiite didn't do well at that.

About the rest... standpipes and dummy plugs, perhaps. I know that @kaya can tell you how to bench test that HPOP. I'm pretty sure you just spin it and see if it sucks on your finger. The details are clearly better left to him...

Edited to add...
If it *was* the IPR valve rather than the ICP sensor, that is a little more involved to swap out. I'll give him an extra 45 minutes on that. So... IMHO... unless his posted shop rate is $1000/hr, he's robbing people.

he did the icp sensor, telling me it was all the way down below the turbo, having to tear the truck apart. I was on vacation and the boat was in the water at the lake and needed the truck fixed and didn't want to do it myself, so i let him. now i do my homework and find that the icp sensor is on the front right valve cover, he charged 5.22 hours of labor @ $90 an hour for that sensor!!! its literally a 2 minute job!!! he's a crook!! But since AAA drove me there, dropped me off, and said he's a AAA certified mechanic, they warranty his work. so should get that all back. and HOPEFULLY they pull his AAA cert.

forgot to say.... checked the ipr, it looks perfect, screen looks brand new, no dishing, no tears.

 

[djmaguire]

Yes to the ICP sensor. He has some 'splaining to do.

I completely get the urgent situation that you were in. This is no way on you. The AAA angle is the right one, too.

Good regarding screen. If the HPOP sucks (you know what I mean), you may end up reinstalling and then air testing.

 

[waistline00]

how much should the hpop suck? gear facing me on the bench, I'm putting my finger over the hole on the bottom side on the left, (stc fitting is on the right) I'm pretty sure this would be the inlet for the oil, clockwise turn nothing at all, counter-clockwise turn it slighty grabs my finger but not enough to really hold it there. is that all the pressure i should expect? it did pump the oil that was in the pump onto my floor though, so it is pumping something.

 

[djmaguire]

This is the quote that I remembered:

Put your finger over the suction side of the pump (bottom) and rotate the gear. Does it create suction on your finger?

The problem for you is that *I* have never done it. I only read of his doing it. I'm hoping that he'll stop by. He's the finger sucking expert...

 

[waistline00]

hahaha, got it, well in the finger sucking experiment so far, i spun it by hand, tiny sucking but possibly tiny blowing also, hard to tell, hooked it up to a makita drill thinking motor spins it faster than i do, still nothing. thinking maybe it needs oil in it to create suction...submersed the inlet in oil, spun with makita, nothing pumped. thinking maybe it needs to be primed to pump, flipped it upside down, filled inlet with oil, used makita, still no oil coming out the stc fitting.....thoughts?

I had a very similar problem with my 05. Tested damn near everything, replaced STC, ICP, IPR sensors and a **** ton more than that. FICM tested fine, so I finally gave up and brought it to my buddies diesel shop. After a couple weeks of him not being able to figure it out, he said **** it and swapped in a spare FICM he had laying around. No problems since. Very strange.

i have done ficm twice before, maybe it went bad again? but it is showing 48v hot or cold on the scan gauge

 

[waistline00]

anyone know how to test the hpop on the bench see if its pumping or not?

 

[Beerent93]

I can't see your HPOP being bad if the system is running fine till you shut it off. Hot restart is your issue yeah? I would lean toward something in the oil rails but that's me. Could be an HPOP, but to me unlikely if it runs till you shut it off.

 

[waistline00]

yes runs perfect until its hot and i turn the key off, then no restart. cools down, runs great again, tows the boat, drives around, everything. until i shut her down hot. then no bueno.

 

[LucyGoosey]

Have you checked the low pressure oil system? Might be a long shot, but it's easy to test.

Remove the oil filter and cap, have someone crank the engine for a couple seconds at max and watch down into the filter bowl to see if the oil level rises quickly. If it doesn't, you've got an issue there.

Guys guys guys. That test id mentioned was for a specific thread on an 04 where he was building 0 ICP. It's definitely not a valid test for all instances lol.
On a no start hot, low ICP, get the vehicle to temp to induce the symptom. While no start is occurring, does the oil pressure gauge rise? Pull the oil filter cap and check that you're building adequate supply. If so, air test. Could be an injector o ring, among many other possibilities.
-confirm supply
-air test

He already pulled the HPOP. That's why I thought of you and the bench test.

I know that you don't *want* the HPOP pump on the bench. ...but it *is* on the bench.

 

[kaya]

I'd throw it back on, and air test.
I just didn't want that test I'd mentioned to circulate as a valid test. It was just a generic check for any pump really that was in question of building any pressure at all.

 

[waistline00]

ok cool, ill throw it back on, i really pulled the hpop initially expecting an easy fix and to change the stc fitting, then to my dismay it was already changed. i got the air fitting on order should be here tomorrow, ill get the hpop back on today, and do the lop system check. the gauge was coming up when hot, but I've heard thats not always 100%. do i need to put the hpop cover back on to air test/lop test or just leave it off so i can still see the hpop?

I will never mention your finger sucking again. Promise!

 

[waistline00]

haha thanks, i was feeling pretty discouraged of my abilities.

Hey what people wanna do at their own leisure ain't my business :look:
But as far as confirming a good pump, nope
