Ford 7.3L Power Stroke (1999-2003) :: New HPOP And Injectors - Long Cranking About 15 - 30 Seconds
May 8, 2017
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?

So I have a 2002 7.3 Excursion and I think it is low on power. ICP is falling on its face when on a 60 or 80 HP tune. I have some boost leaks at the plenums and will work on that but that shouldn't cause my ICP to tank at full throttle. Following are some numbers I pulled with WOT runs up a 6% grade.
16PSI BOOST
EXHAUST PRESSURE 40
ICP 1900
80%IPRDC
this is with the 60 or 80HP tune on my DP-tuner. If I ease into the throttle I get
2700 ICP with
45%IPRDC
but if I stomp on the throttle it stumbles and ICP tanks.
Running the stock tune I can maintain
2700ICP at
40-45%IPRDC
Is this my HPOP being weak, or worn out injectors, to much of a tune or a combo of all three?

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 just finished installing a new set of injectors, standpipes and the blue spring kit on our 2005 Excursion 6.0. The truck idles and runs much better but now it takes almost two seconds of cranking to start the engine. Cold and hot are the same and the length of time between shut down and start doesn't seem to matter either.
What to check? I am planning to check the ICP tonight when I get home. Could I have air trapped some where in the system? This is my first powerstroke so I don't know if this is a possibility.

This applies to a 2001 F-350 with 73,000 miles on the engine. Engine oil level is good, batteries charged, HPOP reservoir is full and passes Cody test with flying colors. Fuel pump runs for 20 seconds at key on. Start takes about 6 seconds. If I shut the key off and restart immediately it starts in under 2 seconds but if I wait about 30 seconds it's a 6 second start. Here is an AE that I ran on it, it has me stumped. FWIW it seems to start quicker when AE is hooked up. ?? An odd whir type of noise comes out from somewhere under the hood when I first turn the key on and when I clear the codes with AE.

Background on the vehicle, Last week installed Swamps 200cc/30% injectors with a 38r. Had swamps reburn my chip for the new upgrades.
But heres the problem i noticed starting the truck was a little harder ( longer cranking ) till it would start never thought of anything since i read air gets in and can cause it but then yesterday and today its taken 30 minutes to start the truck since i have to do a trial and error.
The truck just seems like the batteries are being drained or something along those lines. i also noticed my gauges keep resetting back to blue( default color). Today I plugged a battery charger up all good voltage i charged them so both read 14v and still no start. So a couple of attempts at starting with chip in and ICP on nothing
I unhook the chip and ICP get a half start then eventually it starts. After then i can hook it all back up and it starts good for the rest of the day but for what ever reason after it sits all night it doesn't want to start up right away. I'd like to figure it out today since id rather not wake up at 4am and attempt to do this all before work each day.
I noticed that my gauges would reset to the default color after each turn off. So i unscrewed my ECU and then redid that to make sure its tight. along with making sure the chip is seated properly. after that it stopped resting my gauges. Whether that's the issue or not i cant say but ive been checking my HPOP oil level since i stopped driving it around 1400. and hasn't changed oil levels are good. I plan on starting it before I go to bed around 2200-2300 just to check and see what happens.

I was going to an appointment today and was going about 35 MPH and the truck just kinda sounded like all 8 injectors went into spaz mode for about 1-2 seconds. Initially I looked at the oil pressure thinking the oil pump went out. The engine/idiot light came on during the event and went off. But did not stall out in traffic. I was right in Green Bay Ugg that would have sucked.
I was a few minutes early and plugged in my Superchips reader to see what light code was there and it was a 1211. I have two questions for everyone.
1) Should I disconnect the ICP and check for oil, if so replace?
2) What hypothetically happened?
I now have a slight miss like a injector or something is not happy in one hole.

I've got a99 F2 50 super duty with a 2000 2001 motor. I got the truck in the beginning of last winter so this is my first summer with it.
When I first got the truck there are injector issues with the truck. Since I fix the issues there has been little problems out of the truck however it's still suffered misfires when Cold but once up to operating temperature it was fine. Yesterday I had to go with a friend before leaving for the trip I checked the oil it was full and appeared normal the trip was about 150 miles. I came home park the truck after everything was done. This morning I came out started the truck everything acted as it should... truck fired right up everything was great went and dropped off my trailer at the yard come back got fuel when I come back out from paying for the fuel the truck took about 30 seconds to fire up I checked my gauges and torque pro and everything seemed normal. So on my way I went.
I drove about 10 miles on the highway to the place I had to be when I got done doing my business I came back out to start my truck and it did the same thing this time however it took longer to start I managed to drive about a mile down the road when I noticed my old pressure gauge flickering and my Oil pressure light on I immediately shut it down and coasted into O'Reilly's parking lot I check the oil in the truck and it was empty according to the stick I added two whole gallon.... With it filled back up down the road I went. So currently the truck is still suffering from a long hard starts it takes 30 to 45 seconds before it all actually fire up once it fires up everything appears to be fine however the truck is slowly smoking a bluish black color... It's never done this before however I've never had this truck in the middle of summer when it's real hot out I don't think this is normal.
The truck doesn't appear to be down on any power actually it, acts as if it might've picked up of some power it is felt real peppy today compared to other days. Also I might note that about a week or two ago I started smelling diesel like either really rich diesel or raw diesel wasn't too bad but I just got whiffs of it for now and then. Now there is a burn oil smell present from the exhaust. Like I was saying earlier when I first got the truck I had to service the injector O-rings... I was told that the miss firing when cold was caused by the Poppitz sticking. The misfire hasn't been present since it got a little warm outside like I was saying it was only when the vehicle is cold.... Just thought I would mention the injector issue not sure if it's relative or not..... My thoughts are it's back to an injector issue or O-rings or possibly did I wipe the motor when it ran out of oil. I am not aware of where the oil went as there is been no leaks or drips.

I am a longtime 7.3 IDI guy with an 88 F350 crew so i know about diesels. But this is my first electronic diesel. I picked up a 2001 F450 2wd auto 260k miles. it used to be my work's truck but was stitting for a year and now i got it in "non running condition"
I towed it home and got it started by replacing the batteries and using the block heater.
As expected it took a few tries of long cranking to run the first time. runs pretty good and no smoke. what surprised me is it still takes about 5 sec of cranking to restart each time when warm too. any direction you would look with those symptoms? HPOP, IPR?
i am pretty sure the glow plugs all work because mechanics had replaced all that stuff. but i know back when the truck was last used it would still never start cold unless plugged in (even in summer).

I have a 2002 F-450 crew cab 2wd automatic 7.3 diesel with 298k on the body and about 120k on a Jasper engine. About a month ago I started it in the morning to let it warm up. Went to make coffee. Came back and it had died. It was low on fuel and I didn't pay attention. Played hell getting it primed back up. Now if I don't let it warm up for twenty minutes it won't run worth a flip and has been dying out. Changed fuel filter. Unplugged ICP. No change. When I crank it it will turn over for about thirty seconds then oil pressure gauge moves, then engine starts to run very roughly. It will die. I repeat a few times. It will eventually start and start and stay running. Blows whitish grey smoke until it warms up. No loss in power till CEL comes on. Still not too much loss. Sometimes it takes a long time to get it running. Sometimes it will die after I get out of the driveway if I don't let it warm up. Truck was serviced maybe 3000 miles ago. No water in fuel. New fuel filter. New air filter. It is a company truck. I work for a small company building cell towers.

I have Warn hubs that I have to lock in. All works good. A/C goes to defrost at first when cranking but then runs fine after a couple seconds. So, I was thinking that maybe my pump is running all the time. Who knows. I'm sure all my vacuum lines are dry rotted. What exactly is the need for it exactly and what's the best way to cap? Hoping to do it at the unit itself if possible.

I had the engine out of my truck (7.3 with e4od) to do manifolds. Anyway, I got it back in and started it up. Since there was air in th fuel lines it had to crank a couple seconds but started up. I looked and now fluid coming out, then it sat for a few minutes running and I took it for a drive. While sitting in the driveway it wa smoking a bit. But I thought it's from the oil I got in the exhaust while drilling two of the manifold bolts and soaking the bolts with ATF/acetone. After about half a mile I thought that maybe it's more oil then that would cause... So I went back. I looked and the inside of the exhaust is covered with oil, and the rear of the engine is also.
When it was out I capped all of the open ports so I could pressure wash the grease off. Also, I flipped the CCV so I could do the delete. During instal, I missed the cap on the CCV and it was not able to breath. I think that maybe it built up pressure and blew the valve cover gasket? It looks like it's coming from the right cover on the backside; I had not taken this cover off while the engine was out. How much pressure does it build? Is it possible that it could have blown the gasket out? I have done the oil cap trick to test blowby and it always passed the test. What it could be? For the leak on the engine and why it's in the exhaust?

I have now replaced hpop, injectors, cups, gpr, batteries, uvch on both sides, icp and ipr on my 2002 F550 and it still has a long crank to start.
It has been driven about 1,000 miles since then and no change. I have no codes except buzz test produced a high to low 1272 1274 1276 1278 one time. Cannot get that to happen again.
It is taking 4 seconds of cranking to start consistently hot or cold. It always starts but cranks for what seems like too long compared to my other 7.3s. I have included a screenshot of the data and am curious on what everyone's thoughts are as I am out of things to look at!

6.0 has had dummy plugs and stand pipes replaced and still has a long crank when cold. The kicker is that it doesn't happen when the truck is parked nose up in the driveway. It only happens if the truck is level or back into the driveway. I suspect it's that the HPOP is losing prime from somewhere.

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.

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?

I have a 7.3 and I think it's leaking oil out of the HPOP but I'm really not positive.
