Ford 7.3L Power Stroke (1999-2003) :: 2002 F550 - High RPM Clicking Noise
Aug 18, 2016
I just did an engine swap and have an odd noise that I was curious on where to start. It sounds like a buzz test on an injector at 2,250 rpm and gets louder as rpms increase but starts out very faint and get louder. Makes noise converter unlocked and locked in gear under load and free rev no load.

-Regulated return fuel system
-New injectors all AD
-Stock tune

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!

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.

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?

The last couple of days with the temps in the 50's, my 2000 F550 with a 7.3, will start normally and idle fine. When I try to drive it, I get less than a quarter mile and it just looses power and will die.
If I flutter the pedal, sometimes it will keep running, very poorly. And when it does this, it is putting out blue smoke. After it does this, it will run fine. Just like nothing is wrong.
What do I look for, or is this normal. I have had the truck since last October and this is the first time it has acted like this.

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

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

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.

So finally got my truck running due to a fuel issue. Anyways been driving it for a week or two now, and I have a strange problem idk if it has been covered here or not.
Driving around tow etc if you come to a light or whatever and stop the rpms stay at 800rpm. Now if you shift it out of gear and back into drive the rpms settle back down around 650. Where is should be.
My guess is the torque converter is not disengaged all the way when it stuck at high rpm (800-900) for this situation. No cel, slippage, or crazy noises
2002 7.3 power stroke all stock right now @160k black crewcab
Previous owner had a tunner on it but not anymore. Could it have smoke the trans???

Does the 2002 7.3 have an automatic high idle in cold weather?When you start it after it runs for a few moments it goes into high idle until you hit the accelerator. I had a 96 powerstroke before this one,it didn't do this. Just wondering?

I have a 7.3 Excursion, 234K Miles, 4R100 Transmission. Today I was in a rush to take one of our dogs to the vet, when I hit overdrive going up a hill, it almost sounded like a clicking noise and I was steadily losing power. I came to a stop sign and put it in park and it started to develop a constant lope that was rough. Whenever I would step on the gas it would put out white smoke which it has never done before. I was able to take it a couple miles before it did the same thing except this time it shut itself off.
Recently I have been having transmission issues as it feels im losing first gear. A while back I noticed it would idle slightly in park every now and then. A couple days before this happened, I came to a stop and my truck started loping slightly and first gear IN DRIVE felt very very weak. I have recently replaced the cam position sensor as well as the ICP sensor. I'm at a loss, I plan to do a ZF6 transmission swap very soon and this is only making me panic even more.
I never dog the truck, take it mudding, etc. Oil is changed every 3-4,000 miles. I did however get it scanned a while back and I believe two codes came up for two pistons, also did an injector buzz test and they all sounded strong.

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 bought a 2000 Ex PSD 4x4 in september. I have refreshed the suspension in the last 4 months; leafs, shocks, etc. I developed a vibration over 50mph after I installed the suspension and have been chasing it since.
I have replaced the U Joints, professionally balanced and lubed driveshaft twice, adjusted driveshaft angle to less than 1*, replaced the flanges for the TC output and the driveshaft companion flange. I have not touched the diff, but there is no decernable play in the pinion or leaks. Also, I removed the rear housing of the TC and replaced the output needle bearing and seal 2 weeks ago.
The output of the TC still has 1/4" play and a clicking noise coming just forward of the chain section of the TC. I assume the play is coming from other bearings on the main shaft in the TC.
I am about to purchase a remanufactured TC, but before I do, I need a reality check. Is it possible there is damage to the output bearing of the Transmission or something else?
I don't want to buy a TC to put in and experience a TC failure again in a short time. It doesn't make sense to me that there would still be so much play after changing the output shaft needle bearing of the TC if the TC main shaft is supported not just from the TC bearings but the output of the transmission unless there was possible play in the output of the transmission.

I have an 02 crew cab SB 7.3L. The best way to I know to describe it is a sorta like a metal ringing noise. It just started this afternoon while pulling a 9k camper. It only does it under load. Boost stays the same and it happens in all ranges from 5psi to 15psi. It is intermittent. It sounds like it it coming from the turbo. I pulled off the boot and could not feel any play on the intake wheel.
After unhooking trailer and taking for a test drive I can not get it to do it again? The turbo was rebuilt about 4 years ago with a wicked wheel but has only seen about 18k miles since the rebuild. A quick look at the boots appear good but didn't get to take them off before going to work. I will try to post video.

I have an 02 F350 7.3 6 speed with only 86,000 miles on it ... Ive owned the truck about a year and a half now and ever since i can remember the transmission has had this growling/Groaning/Vibration sounding noise when ever Im in 1st or 2nd slow rolling with barely any throttle. Itll make the noise going slow and as soon as i let out on the clutch and start moving, but once i give it a little more throttle and start moving at a more proper speed for the gear, the noise fades away ... Id assume its just the transmission making noise due to the low speed and RPM when slow rolling or just starting from a stop.

Moving my worldly goods from California to Oklahoma in a rented 26' box truck with my wife following in our '02 F350 loaded to the gills with my lathe, mill, air compressor, weld and assorted machinery. Just west of Deming NM it started to blow lots of white smoke and down on power. Some rattling noises from the engine when throttled up & won't reach 3000RPM.
Had it towed to an impound yard for storage. Plan on sending a flat bed to pick it up when we get to Tulsa.
Any experience with a tilt back trailer capable of loading & transporting this truck that weighs around 17,000 pounds? My plan is to continue on to Tulsa & make arrangements from there.

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.

I just changed u-joints and the carrier bearing on the rear driveshaft. I now have a "howl" somewhere back there. The noise starts around 30mph and goes away around 40mph. There no vibration associated with it. The sound goes away after driving for 15-20 minutes.
I double check all my marks on the driveshaft to make sure I put it in the way it came out. I put it up on jack stands and ran it up to speed but couldn't replicate the sound that way.
The truck is a 2002 F350 7.3ltr DRW.....

I have a Stock 02 f350 7.3 with 66,000 miles ... I'm sure this has been covered plenty if times, but I notice more so on cold days (-20 to 30). My truck after starting and even letting it warm up for a period of time makes a hissing sound from the passenger side of the cab near the dash/glove box area, Like I said I've only really noticed it on cold days ... It usually occurs between 1200 and 1800 rpm and it's a very touchy noise, for example I only really hear it when I'm cruising at a consistent speed, if I get on the gas a little it goes away till I bring it back to consistent throttle cruising then it comes back, same goes for when I let off the gas it goes away until I give it a steady consistent throttle again ....
