Ford 7.3L Power Stroke (1999-2003) :: New HPOP And Injectors - Long Cranking About 15 - 30 Seconds
I recently did the following work:
New Injectors
New T500 Hpop
New IPR
New ICP Sensor
New UVCH/Glowplugs
New starter
Been cranking about 15-30 seconds each time about a dozen times now. I've pulled the icp and the hp crossover and have oil flowing at each.
ICP builds to about 240 psi and at a 98% duty cycle....so I assume there's still some air in the system. I"m not getting any sense that the engine is trying to hit. Do i just keep cranking?

Just replaced all hpop orings. Injectors loud after start up at idle. Guessing air in lines. How long do I need to drive before all air out of lines and everything back to normal?

I have a bit of a quandary with my 6.0 and I'm wondering how it compares to others. If you have a hot or race tune (example: super panty dropper) on your 6.0 with stock injectors, what is the peak high pressure oil that you see at full throttle?
Need to know high pressure oil PSI @ full throttle, year (or better yet which style hpop you have if you know), if your ecu tune is a "race" tune, and if you have any FICM tuning.
Ford 7.3L Power Stroke (1999-2003) :: No Smoke On 140 Tune But Low Boost?
I bought a ts 6 position from kt performance with PHP canned tunes pretty much and on the 140 tune I get no black smoke under throttle, now I would imagine this is normal with stock injectors because im sure the turbo can keep up somewhat. But the problem is I only make 16 psi max so shouldn't I be dumping black smoke? I know the low boost is because I have a hole in the intercooler pipe next to the power steering pump, but do I have low fuel pressure? I would imagine with only 16psi all the fuel will not be burnt. Hpop can hit 2800 and hold 2500. But ipr hit 80% under full throttle at 3k rpm and had trouble shifting but other than that never sees over 45%. I want to know whats going on with the fuel not boost, just to clear things up. And I don't really feel any power loss im stock. 99 f350 7.3 4x4 long bed cc
And just to be clear I am NOT trying to Roll Coal but a nice smoke trail when flooring it past people who cut you off would be nice
Ford 7.3L Power Stroke (1999-2003) :: Chip Or Tune Increase MPGs?
My f350 has 300k on it. 95% of its driving is on trips of 22 miles or more at highway speeds. Occasionally long trips (going to put on 3k miles in 8 days here soon)
Want to drive the truck to 500k miles...but wondering if a tune or a chip would change the mpgs and not hurt reliability? I know its not a Honda Civic...I am not looking for 35mpg....would love to pick up a couple more than I have.
Ford 7.3L Power Stroke (1999-2003) :: Leaking HPOP And Now CEL Is On
I did the extended seal kit and non-serviceable plug on my HPOP and now the CEL is on. It is throwing the below codes. The truck in all reality runs fine and even a little better on a cold start than before resealing, just the CEL is on.
P1280
P1209
P1282
P1212
P1211
I cleaned the IPR when it was out when I put new seals on it but could it go bad by just taking it apart? The ICP and IPR are definitely plugged in. The truck is all stock, no chips.
Ford 7.3L Power Stroke (1999-2003) :: HPOP Dying - Fix?
I started "Hard Start at Operating Temperature" you can probably tell that 300k has done a number on my HPOP. I'm wondering what to do... do I buy a new pump from ford? Buy from ebay? Or is there a good pump rebuilder in the Portland metro area? I've heard they are almost impossible to rebuild.

Pulled the HPOP reseal an oring that was leaking oil. Feel confident that I made sure the check ball stayed in place. Torqued the bolt to 96 ft lbs. Have fuel in the bowl.
We have cycled the starter about 20 times for 15 to 20 seconds. Batteries are charged.
Here is what the AE scan tool is saying after a few seconds of cranking:
ICP -160
IPR - 0.43
Duty - 63.67
Do I need to get a different reading/test.
I have read about stuck open IPR valve giving the low pressure problem, but the truck was running prior to pulling the HPOP.
Lets say I left out the check ball. Would the scan tool show 0 pressure? (Trying to rule out the check ball)
How about if I didn't get the spring seated in the high pressure oil fitting and instead it is hung on the threads and is compressed inside the HPOP. Could that be the case?
Not for sure it makes a difference, but the truck did fire off once on Ether for second.

Do I have to remove my fuel filter and bowl to attempt a repair on my HPOP leak?

The leak drains into the first valley of the block. This is after a cleaning and about 300 miles driving. I thought it may be the IPR but, it's looking pretty dry:
Some more pics .....
The HPOP line fittings are dry too. Where else do there the HPOP's tend to dribble a leak of oil from?

View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: Replaced HPOP Now No Start
This started out as a turbo pedestal O-ring change (leak down the back of the engine). Since I was going to take everything out to do that I figured I'd reseal the fuel bowl and hpop. Wound up replacing the up-pipes as well. Went ahead and changed the ICP and CPS. The truck started rather easy as I've heard its hard to get the air out. I drove it about ten minutes and then noticed it was leaking oil so I went back to check it. I found that it was leaking from one of the output fittings on the hpop as I guess when I tightened it back up after putting on new orings I damaged the pump by over tightening.
The oring and fitting were fine it was on the pump threads I guess. Anyway trucks got 280k miles so I just bought a new hpop from the stealership. Went home and installed it and the truck won't start. Pulled ICP out and cranked no oil coming out. The only other thing would be ipr (I cleaned with brake cleaner and air tip before putting in the new pump) so just to know for sure I bought a new IPR from the stealership and still NO Start. I didn't fool with anything else don't know what it could be. I checked the bolt in the front cover (tight), got to be a BAD (new) pump right.
Ford 7.3L Power Stroke (1999-2003) :: Removing HPOP Reservoir Cover?
I need to get the HPOP reservoir top cover off so I can drill/tap a gauge probe into it.
I see torque-head bolts, and a few long bolts that go all the way down into the HPOP.
Unfortunately I cannot get two of the torque-head bolts out because they only un-thread several rotations before the heads of the bolts hit the edge of the fuel filter canister/bowl.
Any tips or tricks?

Ford 7.3L Power Stroke (1999-2003) :: Cranks But Won't Start After HPOP Service
Removed and resealed HPOP and fuel bowl. Now she won't start. Ran fine before pump & bowl was serviced. I had leakage that I wanted to clear up. I have made no less than eight 15-20 sec start attempts with out even a cough. Reservoir is full, fuel in bowl and over 140 RPM when cranking.
AE info:
IPC duty cycle - rises to over 60% during cranking
IPC voltage - .18 all the time
IPC psi - 0 all the time
I did verify I placed the ball between the pump face and the "non serviceable" pin. I did leave out the spring and check valve seat from one of the output connectors. That has been corrected.
Ford 7.3L Power Stroke (1999-2003) :: Leaking HPOP - Step Up To Adrenaline
about to fix my leaking HPOP and step up to an Adrenaline. Looking at replacing the discharge fittings when I do and have a quick question. Dieselsite instructions say the oring seals it and to only run it down to where the fitting body touches the pump. Diesel orings instructions say the 680 locktite does the sealing and to torque to 25 ft/lbs.

What's better good options on a upgraded HPOP? As of now I have a stocker, it's getting low on pressure when even on my 50hp setting.... Was looking at T500 and Adrenaline. Any others could recommend? I'll be doing injectors down the road here too.
