Ford 7.3L Power Stroke (1999-2003) :: 2002 - Shuddering - Diesel Fuel - Damage Engine?
Jun 7, 2016
02 7.3L SD Im on a long haul and think I might have bought some bad diesel. It is shuddering a little kind of like a miss. It started right after I stopped for fuel. Is this going to damage my engine to keep plugging along? Is it just going to run kind of rough until I burn up the bad fuel? Ive got about 200mi to go so just needed to know if its safe to keep driving or am I going to be stranded.

There was no power getting to the fuel pump on my 2002 Ford F250 73 diesel traced it back to the inertia switch no power in or out but I'm getting power at the fuel pump relay put the code scanner to the PCM and no communication....

If there is indeed diesel fuel in my coolant, what is the most common cause of this problem? Truck has low power when towing 8 tons.
I've replaced water pump due to truck overheating and blowing off radiator cap during first hard tow up steep hill.
Replaced all radiator/heater/coolant hoses.
Replaced radiator.
I've also flushed the cooling system 5+ times now with coolant flush and distilled water. Each time, less and less evidence of brown-colored stop leak.
The stop leak looked like diarrhea, slightly chunky. After the third flush, stop leak in coolant lessened.
HOWEVER -- 4th/5th flush of coolant each still looked like brown milk. Coolant has a strange chemical smell, possibly diesel fuel.

I will start with what I have done to my truck. Hutch and harpoon mod, fuel pump, new orings on fuel lines, fuel filter, air box, 4" exhaust. My issue only happens when my engine is warmed up and I put it under a load(driving up a long hill or pulling up a long hill). My truck starts to shudder and feels like missing until it looses all power to where it won't even pull itself and will just barely idle. It doesn't die though. I watch the engine oil temp and it seems to be around 195-200 when it occurs. I can turn the truck off and let the oil temp cool to 150-160 and then start the truck up it will miss for a second then clear up. I will start driving again and it seems fine until the oil temp gets up and start putting it under a load. I have read many posts and can't figure out exactly where I need to start. Some of the codes I pulled are P0603, P0470, P0732, P0542 and P1211.

I have been smelling fuel on and off for the last few weeks. I thought it was the fuel bowl drain valve so I ordered the kit for the whole fuel bowl from diesel o-rings. I did the rebuild this morning and I don't see any visual leaks. Still smell a strong odor of diesel though. The lower engine cradle is all wet and the valley is still a little wet too. Could I still have a leak and if so where to look? Could it be just wet still from draining the fuel bowl and needs time to go away?

I have a may 2003 6.0l f350 4x4 ,autoenginuity scanner, recently bought the truck starts fine and idles well then when engine get warm it starts to smoke unburnt fuel (white) volume of fuel desired on scanner goes from about 14 mm~3 to 27mm~3 and starts to run rough if you depress the acellerator the motor smooths out and the fuel desired goes down. No coolant smell. egr cooler removed ,oil cooler replaced, exhaust back pressure sensor and tube cleaned .ebp sensor koeo 14.2, eo 17 but jumped to 54.0 when map was at 17, bp 31.20 .... The AE is new to me Also found a superchip tuner under the back seat ...

I just got delivered a 7.3L from down south. Batteries were dead so replaced both. Fuel was a couple notches above red line (much closer to red line than 1/4 tank) so I added about 7-8 gallons.
It will crank forever and ever...Won't start.
With starter fluid it starts but not strong enough to pump the pedal and rev it up to keep it idling.
I know s-fluid is bad but if I continuously spray with key turned forward it will run but as soon as I let go of key it shuts off.
20 degree weather and it was delivered to a parking lot so I cannot plug it in.
Was told to check filter cap, turn key, and see if it fills bowl with fuel....if not then it is fuel pump. Someone else mentioned that it could be bad crank position sensor? Does this sound like fuel pump?

the past few days I started smelling diesel fumes in the cab of my truck with bent on and also at the front of the truck when installing new bumper and winch. It's not real strong in the cab but pretty stout at the bumper. I have poped the hood and made a quick visual inspection and from underneath the only evidence of any leak is some power steering fluid which is a different issue (I think)
a week or 2 ago I was cleaning the Ex and noticed 2 or 3 drops of red fluid on the concrete under the Ex I crawled under and looked up and the steering knuckle was pretty wet. Popes the hood and took a look from the top and the power steering pump was sticky and dirty but the only fluid was on the top of the cap.. I'm not real familiar with the set up on the Ex but I have heard the PS support the break booster. From visual inspection it seems as though the fluid is coming they the small (vent?) hole on the cap. What I can/need to do to stop this?

I bought a 99 f-250 7.3 a month or so ago and am impressed with the level of knowledge and hospitality you all show. This is my first diesel so I am completely new to a lot of the issues that occur with one and many of the diagnostic tests needed to troubleshoot.
When I purchased the truck the guy said it was very cold natured and I would have to plug in the block heater if it got chilly out. I didn't realize just how bad that problem was and have since had to keep it plugged in even on very mild nights to get a quick start. I have been very careful to let it warm up for 15-20 mins before I start driving it.
Also, I have noticed at around 40-55 MPH and light pressure on the gas I get a shudder, it was worse before I added a friction modifier to the oil but it is still there constant in overdrive.
As I was driving two or three days ago in a light rain (the first since I bought the truck) I noticed the SES pop on and stay on. Being new to the diesel world I immediately pulled into Autozone and tried to get a code, but with no luck. The truck has been running a bit rougher since the light came on and I am noticing a marginal power loss.
So my questions are: Where can I get the codes pulled off? I have been looking at buying a scan tool but the AE is out of my price range and the other options seem to have mixed results. Also, do any of the problems seem to be related or could it just be a few different issues that need to be ferreted out? From what I've read it seems possible for the UVCH to be the issue here, is that correct?
Again, I am really new to diesels so I may have been having loss of power even before this and not known it due to my inexperience.

I've thought I smelt diesel fuel on an off for a while, but never found the source.
Tonight, 17 degrees out I have fuel in the valley and it appears as if the back of the drain valve is wet.
A fuel bowl rebuild is on the short list. Is this typical, the cold weather brings the issue to light?

I'm presently traveling and my '02 F-250 with a 7.3 PowerStroke has developed a pretty steady drip of what I am almost sure is diesel fuel. It's dripping from the very front, from the shroud around the fan and radiator area.
I have some basic tools with me, but no experience on this engine or the fuel system. Does the fuel line go up into the radiator area? What should I be looking for? I'm stranded in a campground until I figure this out.

2002 F350 7.3, MANUAL transmission ZF6.
Bought this truck used for hauling an excavator, and after fixing damn-near everything engine/turbo/and-cooling-system-related ---- it's finally seeing some use.
Just recently started hauling 12,000lb payloads. When I accelerate hard in Low gear, and then shift into 1st and accelerate hard again, I feel the whole truck shuddering. It's like a shimmy-shaking vibration all through the vehicle.
It doesn't happen in higher gears, only when the following conditions are met...
1) Starting from a dead stop
2) 12,000lb payload (heavy)
3) Accelerating hard (Low, First gear)
I would also like to add that I experienced this shuddering vibration very intensely when I put the transfer case in 4wd LOW (front manual hubs left unlocked) and towed 14,000lb up a steep hill in 1st, 2nd, and then 3rd transmission gears.
^^^ By leaving front hubs unlocked and transfer case in 4wd LOW, I was effectively lowering my final drive ratio even more for extra pulling power in 2wd hill-climbing. I don't do this often, only when absolutely necessary. ^^^
I must also add that I do have slightly taller rims/tires than OEM ford WITH the original ford gearing (3.73) so I'm more like 3.51 final drive ratio.

My truck was shuddering in od. So as I last effort thinking it might be injectors I pulled all of them and replaced all of the orings and valve cover harnesses. After all of this was done seemed to do nothing at all. Now a new problem has surfaced. It's having idle problems. It will now idle at 780-850 instead of 650-700rmps. Also on deceleration it will miss pretty bad. Checked all of my injectors again all connections are good and all of the injectors are tight. Not burning any oil. So I unplugged the icp and bam runs like a top perfect running engine. So I bought a new one and plugged it in and itake doing the same thing. So what is going on! Also it was throwing a random check engine light but wouldn't bring a code up I'm completely lost....

Ill start off with my mods and recent maintenance things I have done before fully describing the issue.
E99 7.3l with 190k on the clock
Full 5" turbo back
TS-6 chip
EGT, Boost and trans temp gauge
New ford glow plugs
Re-orings injectors
new valve cover gaskets
new fuel filter and fuel lines
new turbo with a ww2
Newer trans and oil pan
I think that should do it, now for my problem. The truck starts good cranks over once and is running with no hesitation, the engine run a little rough, more than normal vibration at idle almost like a small miss. No smoke at idle.
While driving with no/little load on the engine runs great , but under load there is a good amount of white smoke/ oil smell. The turbo is new and is not leaking oil I have already checked over that and the exhaust is new but there is some oil that is at the tail pipe in liquid form. The exhaust up pipe that goes to the turbo is not covered in oil either
The truck cruising in OD or in 3rd with O/D off around 2k rpms it shudders real bad almost like the truck is going to shake its self apart. but at like 2400 rpms and above its fine. Where is a good place to start the diagnosis as I am pretty new to the Diesel world. From what I've read it looks to be either rings are junk or maybe I have some bad injectors (thats what it feels like to me) but would that cause it to smoke like crazy?

I am installing a fuel pressure gauge into my 02 7.3 I went to the thread the sensor into the plug hole on the fuel filter housing and it wasn't threaded, turns out the sensor thread is slightly smaller and a different thread ... The directions say to install it into the filter housing or the lift pump ... So I'm assuming I have to go the lift pump direction of installing it but where the lift pump is or how to install the sensor into it while not throwing a code or causin problems ... A step by step and even pictures.

What I know the truck was running normal except if I stomped the gas pedal and let off it would not respond again until I shut off keys and restarted this was a month ago now the truck sounds like it has a lope tune.
When I hit the gas pedal it blows white smoke and if I press the gas while idling or driving it floods out I did the spray bottle test on manifolds the drivers side was plenty hot the passenger side is cold you literally can touch while it's running.
The truck sounds like it's only running on 4 cylinders it has gotten so bad I parked the truck. Also this truck always had poor mpg 8 to be exact city hwy and towing nothing changed the mpg at all it used to blow out wet soot that would fall down on the truck and anyone standing near it.

So after hitting a pothole, it would seem like half the engine lost power, after some searching around, i found that i would most likely be the harness inside the valve cover that has lost connection.
Its the right side, so i would need to take of the turbo pipe, and probably something else to get to it.
Since i'm doing this job, what to check out along the way? I want my 7.3 to be as reliable as possible.
I will probably ask some questions along the way, it can be a challenge sometimes to own a car that not many mechanics are familiar with, but as i have read online, this should be a very straight forward fix.
Can the harness be upgraded so it doesn't happen again? Its an 02

Drove 5miles sitting at in idle in bimart parking lot truck shut down
Let sit overnight, went back started right up
2nd Time
Outside Temp: 100
Driving home sitting in traffic slow moving 5mph, truck shut down
Able to start up about 5mins later
3rd Time
Replaced CPS, Air filter, Fuel Filter
Outside Temp: 80
Hauling travel trailer up peak 35-45mph shut down
Allowed truck to sit 35-45mins started back up
Started hauling made it about half mile shut down
Got towed to flat land to unload trailer and haul the rest of the way
Returned to truck
Started right up 45mins later, drove it 30miles home without a problem
I am at a loss i keep reading and seeing HPOP, tin nut, IPR, EBR..
The last post I read was about the IPR : [URL] .....

There is fuel leaking from somewhere on the passenger side of the engine.
What things should I be looking for? I'm thinking injector? Is it easy to identify and replace?

I have a very slow fuel drip off the housing for the fuel filter on the engine. Can't see where it's coming from. It started sometime after I changed the filter a couple of months ago.

My VIN inside the door is scratched enough that the State can't verify it. They need two locations to match the VIN otherwise the vehicle must be scheduled for a "level 3" vin inspection hundreds of miles away. Well I tried to find one on the engine where the DMV can do a "level 2" vin inspection but I can't find it. Where other vin's are on my 2002 Ford 450. Mine is a flat bed.
