Ford 7.3L Power Stroke (1999-2003) :: 2000 F550 Turns Over / Black Smoke From Tail Pipe But No Start
Ok I'm working on a 2000 7.3 on a F550 truck was running but had no power so we changed out all the injectors and glow plugs and rebuilt the turbo now there is no start it turns over and were getting black smoke from the tail pipe. What is going on with it?

Ok, I have a early 99 F550 that had a tired engine when I bought it about four years ago, but I kept using it just dealt with the low power and blow by. But last winter I decided the truck deserved a complete overhaul. New cab, new transmission, overhaul the engine, and everything else that goes with. I tore the engine down to find out it was already a ford reman. Had the heads completely gone through, new pistons, new exhaust manifolds, new turbo, brand new injectors, new 4inch exhaust, new valve cover gaskets uvch harnesses and repair ends for harness side, and a new IDM.
Now with everything back together, the truck starts an idles fine but has absolutely no power driving it takes like a half a mile to get to 45mph. No check engine lights no smoke. I took it to ford they said only stored codes were for ebpv which I deleted out of turbo housing they recommended changing injectors. So i did no difference. They also said my hpop was about 1600 at idle. And said that's enough pressure. I did resistance readings on all wires between idm an valve covers.
Ford 7.3L Power Stroke (1999-2003) :: 2001 F550 - Surge Off Idle / No Power
I have 01 F550 6spd 4x4. sounds rhythmic, smooth at idle but just over 1200 is a pattern surge but doesn't sound like one cylinder, cel is off, ICP and pigtail changed as it was leaking , no change. From what I've read duty on ICP and IPR should be about same % I've included the codes I've gotten, I have the epc disconnected right now as I thought it was a wastegate issue, checking the ICP plug next,anything I've missed? It had a cyl 8 contribution at idle which I hear is common? Will changing CPS work with that one? Think it's a grey one. There's no water in bowl I replaced filter, since replaced ICP, pigtail, and bleeding fuel bowl and new filter the codes are gone but still misses, will be checking uvch, injector buzz test showed no faults. Old diesel guy said to flood with Stanadyne fuel treat?

I have a 1999 Ford F450 Tow truck with a 7.3 turbo. It loses power and misses when I give it gas but when driving normal speed no problems.
I had a ford technician look at problem with a computer and he said number 8 injector . Today number 8 was changed.
Test drove it same problem. I also changed th fuel filter. And I emptied the tank to make sure No water

1994 f250 7.3 turbo problem.. runs great on the level.. Cruises 65 no problem.. We have an 8% grade coming from town and half way up it starts cutting out and sounds like a jack brake under the hood and loses power.. Once over the top it clears out and runs fine again.... I just changed the fuel filters but no luck... I have been wrenching on cars all my life but no diesels..

I am a mechanic and tow operator running a late 99 f350 7.3 6 speed cab and chassis wrecker. This truck has had a hard life and has been neglected for quite some time, and now has become my baby/headache. Truck starts great, idles nice, and will run great for about 5 minutes until it starts billowing white smoke that smells like fuel and loses all power. If you continue to drive it it will die. Sounds like it's dropping cylinders and will barely idle. If you stop for 5 minutes or so and let it idle it will smooth back out and will run great again for another minute or two, then right back to stumbling.
Using torque app, hpop pressure looks good when it's running well. Peaks at 3k, IPR maintaining 30-40% max. As soon as it stumbles you can see the hpop drop to 5-600 and the IPR will climb to 65%. Let it idea bit and they go back to normal, and stay good until it stumbles again.
Ive changed the fuel pump, ICP,rebuilt FPR, change fuel filter, pulled and cleaned the fuel tank (metal tank, no delamination, looks perfect inside). Pickup screen looked good. Cleaned the IPR, cleaned the hpop reservoir, there was no screen inside. Checked voltage at fuel pump, 11.78 across the pump with it running. Pulled valve covers, no noticeable leaks around injectors. Injectors have less than 5k miles. Remans with 100% larger tips.
To me it seems like the lpop is not keeping up with the hpop under load, starving it until you idle and let it catch up. Could it still be bad injector orings? Bad lpop? Something I'm not thinking of?
Ford 7.3L Power Stroke (1999-2003) :: Stalling Out Just Like The Key Is Turned Off About A Mile Down The Road
Early 99 7.3 manual 6 speed. 224,000 miles. Truck starts great and runs great at idle. Starts out in gear just fine and seems to have plenty of power. It will act just like the key is turned off about a mile down the road. Will restart after extended cranking or letting it sit for 15 minutes or so. P1249, P0340, and P1280 codes pop up. Had a professional shop work on it and they changed out the CPS and IPC with factory parts. When i picked it up it had an SES light on but was running fairly well. When I looked under the hood the IPC had been cracked on the plastic part. Replaced it with another new one and it ran fine for 3 days, even pulling loaded hay trailer. Now when driving it, it cuts out for a second or two. It does that every couple miles until it stalls out completely. Restarts after 15 minutes and runs fine. Same codes are showing up.

Here's what I'm dealing with. Took the truck on a 1500 mile trip with no issues. Got home and started it the next morning and it started right up. 1/2 mile from home it starts to run rough and wants to die. It does this for a few minutes and then perks back up and runs fine for however long the trip is. It will always re fire and have no issues. Every morning it's the same game as described above. Within 1/2 from home it's doing this. Seems to be fuel delivery related, but why would it start after sitting overnight, and then after its little fit, run without an issue?
No codes in computer.

Ford 7.3L Power Stroke (1999-2003) :: F550 Rear Diff - While Reversing Clunks?
I seem to not be catching a whole lot of luck lately. The rear end on my F550 has a bunch of play. Going reverse to drive it clunks pretty bad but no ujoints are bad. I can rotate the yoke by hand and hear clunking so i am guessing the ring and pinion are bad, at 100,000 miles. Seems like the rear ends should be more stout than that, certainly look it.
Where to find a source for reman third members since this one had a drop out? Most axle places won't touch it
Ford 7.3L Power Stroke (1999-2003) :: 2001 F550 - Knock After Injectors Replaced
I just replaced all 8 injectors in my 01 F550 with remans from FFD. I have noticed a constant knock at idle but truck runs great. Blowby has no pressure behind it, truck does not smoke. Does this sound like a problem unrelated to an injector?
It did not make this noise before replacing the injectors

Ford 7.3L Power Stroke (1999-2003) :: F550 Backfire And Shot Flames Out Of Exhaust
I was driving my bosses f550 with a 7.3, and while towing a loaded 40' flatbed of hay, it started bloing white smoke and lost all power and had almost no pedal feel. It wouldnt even go past 2500 RPM. Then, all of a sudden, it started billowing black, and BOOM backfired and shot flames out the exhaust. Then, I pulled over at a parts store and replaced the fuel filter, which worked for a while, but then it started blowing white smoke again. Once I limped it home and unhooked it, I took it out and let her rev a bit and it seemed to stop blowing smoke, but it still has less than the normal power it used to have. It has 226000 miles and is completely stock.

Just joined today, I have a 2003 550 7.3. New HPOP, 3 new injectors, new seals on others, new fuel pressure regulator, new fuel pump, sending unit mod to eliminate filters. 733 HPOP pressure, 65 fuel pressure at idle. Truck runs out of fuel pressure after its warmed up and driven about 20 miles. Haven't checked voltage at pump while driving. I had taken it to a seasoned tech of 20 years and he had replaced HPOP and 2 injectors and it does start better but problem is still there.

Having trouble with motor, driving home one day heard a noise under the hood. Then a lot of grey smoke started coming out of exhaust. Got the truck hauled home notice fuel was coming out at the number 7 cylinder at exhaust port. Thought it might be the injector just put rebuilt ones in, thought I might have received a bad one. I switch the number 7 injector with the number 3 injector. Did not make a difference still have fuel leaking out of exhaust manifold at the number 7 cylinder and a lot of grey smoke coming out of exhaust. Not sure where to start looking next? Could it be the injector cup is the problem?

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!
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Grey Smoke Coming Out While Driving
I didn't notice anything until I was towing yesterday and tried to pass a car to get onto the offramp.
Anyway, I went to floor it so I could get around and, in my mirror, I could see a decent bit of grey smoke coming out. What could it be?
It doesn't smoke at all on startup and runs smooth right away.
Ford Super Duty (1999-2016) :: 2003 F550 - Suddenly Power Loss And Struggles While Driving / Gurgling Fuel Pump Noise
2003 f550 with 7.3, suddenly loses power and struggles while driving. White/blue smoke comes from tailpipe, can smell the diesel exhaust bad when happens, comes and goes intermittently but has been happening more and more often. I uploaded a video onto YouTube to show sound, rough running motor and smoke from exhaust although smoke not that bad in video. Search "shadetreelandscaping" on YouTube in case link below doesn't work.

Took to ford dealer a few diff times for problem and they can't get any codes, can't duplicate problem. After it being in for third time they say had to call ford tech hotline and they suggest replacing injector however can not and will not gaurntee that will solve problem, and obviously dealer isn't cheap for repair. I find it hard to believe that a bad injector(s) would be an intermittent problem as it is or that it would cause fuel pump to make gurgling sound.
Ford 7.3L Power Stroke (1999-2003) :: Loses Pedal And Engine Died When Shifting Gears
I have a 2000 F350 7.3 213,000 miles. Manual tranny, 2wd. It is my daily driver.
No issues until 2 weeks ago I pulled out and began shift gears when the engine died and I completely lose pedal. The engine does not shut off it goes to idle and the lights and power are fine but I quickly lose acceleration. After a couple seconds and a few pumps on the pedal it comes back. The problem is intermittant. Until yesterday it was only in the morning but then happened on the way home from work. Thinking ti was water in the fuel I used an additive to cure the water.
I changed the fuel filter just after I bought it in April of this year. I know there is a Injector Pressure Sensor that could be the culprit. EGR?
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Humming Sound While Driving / Clunk Loudly When Shifted Into Reverse
On my way home from work the other day my 2000 7.3l started making a humming sound while driving. I noticed that it was shifting harder and it began to slam into gear when I would take off from a stop. By the time I pulled into the driveway I had to be half way into the pedal to keep it moving. I shifted into reverse and it clunked loudly and didn't want to back up. I don't know much about transmissions but I'm thinking that it's probably shot. I'm hoping that it's something other than a complete rebuild but doubtful.
