Ford 7.3L Power Stroke (1999-2003) :: Will Cluster From 2003 6.0L Work In 2002 Model?
I have a 2002 7.3L Screw 4x4. Will a 03/04 6.0L instrument cluster work in this truck? The 2 clusters appear identical. I put the 6.0 cluster in and the trans temp, and coolant temp gauge will not work. All the gauges sweep when it is powered on, but the coolant and trans temp lay flat, and the check gauge light is on. All other gauges and functions work. When I put my other cluster in, all gauges work fine. Is there a difference in the VSM, PCM, or the SCP communication?

I just got a 02 f250 lariat 4x4. 7.3. the dimmer on the dash will not work. The light switch was falling apart any way so I replaced it with motor raft switch. Didn't fix it I checked the fuses for the dash and lights. Can't find anything. It does have an aftermarket CD player and those light work with switch. Also it has the mirrors with turn signals and run lights. Neither works power mirrors work fine but no lights. On either side.

I have a 2002 7.3 e350 quigley 4x4 Sportsmobile with 312k miles. 2nd owner. Bought it with 295k miles 2 years ago. From what I gathered the tranny is original.
After reversing at a downhill angle, stopping, and shifting the lever to Drive, the tranny doesn't seem to put Drive in gear and depending on the angle of the slope, the van will roll back or barely creeps forward even with throttle. Put it in 1st gear, and the tranny engages that in gear and drives forward no issues, then I can shift to 2nd, then Drive and the tranny shifts fine after that.
No weird tranny noises or clunking. Noticed this issue about a month ago or about a couple thousand miles ago. Did tranny service (drain, filter, fill) at the ford dealership at 305k months ago.
I can only replicate this issue when Reversing on a down slope. On a flat surface van Reverses and engages Drive like normal.
Ford 7.3L Power Stroke (1999-2003) :: Tires Sound When Under Load At Speeds Above 37 - 40 MPH
The issue: when I reach 37-40mph I have a new sound which I believe is the transmission 4R100. It sounds like a flat spot on a tire, or the sound tires make when they leave the sticker on them. The cadence of the sound is slower than the rotation of the wheels.
If I let off the accelerator, the sound stops, as soon as I add load by pressing the accelerator the sound returns. If I shift to Neutral the sound is gone.
If I coast at any speed the sound is gone. It is only audible when under load at speeds above 37-40 mph. The cadence does increase as I speed up, but it doesn't sound as fast as the motor is turning (~1900 rpm's).
I monitor the truck with torque pro using the PIDs defined here on FTE. I can see lock-up in 3rd and the shift to overdrive. When in lock-up, I see 1-7rpm TCSlip.
Watching transmission temp as reported by torque, the hottest I see is 183* pulling an enclosed 6x12 @ 75 mph. Ambient temp is 95*. Excursion currently has 240k miles on the clock.
This sound was first heard by my wife two weeks ago. I thought I had tire issues and they needed to be rotated. The sound is still present, and now identified only when the truck is in drive, and under load, regardless of me pulling a trailer.
Yesterday on my 500 mile trip, the truck hiccuped several times which I believe was around the time I was either moving in or out of overdrive. Details in a different thread: [URL] .....
Anyway, I've looked at all culprits and can't find anything with the motor, or electrical system. I can't get to a transmission shop until Monday, and won't have my AE until I get home Sunday night. I have a 500 mile run tomorrow. I checked the transmission fluid and it's at a good level, pink, and doesn't have a bad smell.
Ford 7.3L Power Stroke (1999-2003) :: Front Tires Started Rubbing
About two weeks ago my front tires started rubbing. I've been running the same size tires as long as I've owned this truck, and the PO ran the same size too. The rub is more noticeable when turning up an incline, but I've heard/felt the run on flat ground too. What would cause this "out of the blue"? Are my springs wearing out? FYI...I replaced the shocks less than a year ago, and bought the tires in March.

I have been "fighting" a front tire cupping problem on my L99 F350 Dually 2wd since I have owned it.
I got LOTS of paperwork with it, one of which was a service ticket from the dealer where it was bought new (with VERY low miles on it) saying several passing motorists had informed them that the front tires were bouncing down the road.
I have read this service complaint several times and I now feel that has something to do with it. I bought the truck with 70k on it some 8 years ago-the PO had installed EXPENSIVE Michelin XPS Rib steering tires on it and they were already destroyed by cupping.
I replaced all 4 shocks, and all 6 tires, begged the folks to FIND something wrong/loose/worn out on the front suspension/steering and they found nothing, they aligned it. THAT set of Cooper Discoverer HT tires did exactly the same thing, except I spent a lot of $$ having the tires rotated.
Now I have a set of Firestone TransForce tires on it and its been to a HD truck shop where I begged them to rip into the front end and FIND something wrong-THEY DIDN'T. THEY installed camber bolts and aligned it, yep, you guessed it STILL CUPPING!!
So, now I'm thinking is it possible that the wrong coil springs were installed at the factory causing this bouncing that the original owner reported to the dealer? I have now destroyed 2 more tires and getting tired of it.
Ford 7.3L Power Stroke (1999-2003) :: A/C Won't Work At Idle?
I have a 99 f350 and my a/c does not work at idle at highway rpm it blows cold. but once i let it sit and idle even on 1300rpm high idle it will now blow cold. it blows hot untill i rev it up aroung 2000rpm or drive down the road. I have charged the a/c system it has the proper about of refidgerant in it compressor gap is correct. Is it supposed to be like this? If not what are some things to check?

I have a 99 f350 and I can't get my truck to kick up the idle when it's cold out. There have been mornings in the negatives and still nothing. I replaced my egr tube and cleaned the exhaust pressure sensor. My exhaust back pressure valve opens and shuts while driving at slow speeds but not while at idle, but I don't know if that's related. I replaced the oil temp sensor with a ford motorcraft one. And I plugged my intake air temperature sensor into a buddy's truck with the same motor and his truck still idled up no problem.
View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: 4WD Does Not Work / No Vacuum Leak Signs
In the past, I've had the common issues of vacuum leaks causing issues as evident from the defrost/ac and then finding busted vacuum lines. Changed out and everything fine for a few years. Now, i dont have 4wd but i dont have the tell tale vacuum leak signs. Also, even if i manually engage the hubs, still no 4wd.
I try to listen for the transfer case to engage when i switch from 2wd to 4wd, I think I hear it engaging, but to be honest the 7.3 makes so much racket Im not positive that Im hearing it, or at least not hearing it the way I "think" that i heard it in the past. I seem to recall a distinctive clunk when engaging, now its barely audible if at all. Now when I switch to 4-Low, there is the distinctive sound, and it does goes into low drive, just that its only 2wd-low, still no front wheel action.
I have never had any issues before other than the vacuum leaks, have never had reason to dig into the transfer case for any reason. The only time it has ever been touched was last summer when i had the BTS installed and all they did was remove and replace.
Do I finally need to either rebuild or replace my hubs? Is it possible not to have 4wd even with hubs manually engaged? Or is there an issue with the t-case? Or is there something else going on? I have access to a lift to attempt "driving" while all wheels off the ground, its just not mine and its a tight fit and a pain to get my truck on it.
Ford 7.3L Power Stroke (1999-2003) :: After Wiper Motor Replacement Some Electrical System Won't Work?
I just replaced my Wiper motor last week and noticed something strange. For the last year or so when I turn on the key to start the truck, once in a while my radio, gauges, and other electricals such as windows wouldn't work for a bit, anywhere from a couple seconds to maybe as much as a couple minutes. Since my wiper motor was on the fritz, I pulled the fuse and the radio,gauges,ect. wouldn't work until the WTS light went out, then everything worked just fine, even after I started the truck and the glow plugs come back on.Since I replaced the motor everything works as soon as i turn the key. Coincidence? Or could one of the internal relays on the motor being stuck cause that?

So I installed my chip today. It's got anti-theft, high idle, stock, 50, 75, 100 tunes.
With the chip installed the truck starts. In all tunes except "High Idle" it idles at about 1000... normally it would be like 500-600. High idle position works (1100-1200 RPM). Anti-theft position works - it kills the truck. The throttle does nothing when pressed no matter which position it is in. Stock, 50, 75 or 100.
I removed the chip and the truck runs fine. Did these guys send me one for an automatic? Or do I have the wrong computer in my truck? My computer code is DAC3 and the truck is a 2000 with a manual transmission.
Ford 7.3L Power Stroke (1999-2003) :: Floor And Defrost Work But Dash Vents Not Working
The floor and defrost vents work. It just stays on defrost when you try to use the dash vents. The actuator seems to be working fine. I can watch the arm move through all the motions. and I cant find ANY vacuum leaks. Yes I looked at the hubs and under the hood. May be moving to alaska and kind of need my heater to work properly. . . .

On the final stages of prepping my truck for sale. I noticed today that occasionally while making a right hand turn the signal light will not work when you put the lever in the locked position (no dashboard arrow to the right and no front/rear light). I can pull the stalk upward, but not lock it, and it always works correctly. I am thinking a bit of corrosion on a switch, but I thought I would check and see if others have run into this.
View 1 RepliesFord 7.3L Power Stroke (1999-2003) :: Waste Gate Supposed To Work At High RPMs / Boost?
I understand how the waste gate is supposed to work at high rpms / boost.
I believe that as long as I keep the max boost down, that I can run with the waste gate plugged in order to goose the power a little in the 2000-28000 RPM range. Since the truck is stock and there's no intention of running higher RPMs, it seems like plugging the waste gate is a good idea. I just want to make sure that I'm not missing something.
It appears that the wast gate also opens when at idle and possibly when you let off the throttle. Are these important functions of the waste gate as well?
Here's a chart showing waste gate operation...
Ford 7.3L Power Stroke (1999-2003) :: 2002 F250 - No Power To PCM Fuse
I just finished a cab swap and I'm having a little trouble. Here's a link to what I've done : [URL] ....
KOEO the WTS light, battery light, SES light all stay on and no power to fuel pump. No communication with PCM (using AE). All fuses are good, but no power to PCM fuse (#22). When I apply 12v to #22, the truck will start and idle - but poorly because I still don't think fuel pump comes on. The idiot lights all stay the same.
I did get to pull codes while it was running and got stuff like IAT circuit high (its not plugged in), fuel pump relay short to batttery, and a few other short to battery things (park assist stuff IIRC). I thought that might have something to do with the redneck idea to boost the fuse with an external power source?
Just thinking while typing, I don't have 3rd brake light hooked up yet (just thought of that, I'll hook it up first) and bed/bumper are not installed, so no tail lights or park assist stuff is hooked up. I'm also not using overhead computer, so it's not plugged in.
My next step is to go back through all of the connectors and make sure something isn't 1/2 way plugged in or possibly plugged into the wrong place(s).
Looking thru the wiring diagrams is not a strong subject for me, but I was trying to figure out how power gets to the fuse and how PCM relay works (does it complete circuit to ground to energize the coil?).
Ford 7.3L Power Stroke (1999-2003) :: 2002 F350 - Lack Of Power
My issue I'm having - 2002 F350 7.3L has an 8 inch bds lift with 37/13.50 tires. I realize these tires are big but... while driving 100kms/hr or 60 miles per hour and I hit the gas the truck barely wants to move (without pulling a load). Thought maybe a turbo but I have no mechanical skills so here I am!
2nd issue, there's a bullydog chip in that truck when I bought it. he said he always ran it on extreme. I found it puffs way to much black when on extreme and on performance it seems a lot better so that's where I have it?.
3rd issue, the transmission gauge on the dash goes into red when climbing up hills ( I live in the rocky mountains so a lot!) but the bullydog chip says the tranny is only at its hottest 140C? I don't believe that's to hot but I do believe my truck is derating a little while the tranny gauge on the dash is in the red? is there any quick fixes out there for these issues.
Ford 7.3L Power Stroke (1999-2003) :: 2002 - Loss Of Power?
I have a 02 f350 7.3 with 296,000k its been running ruff lately with a serious loss in power. The truck sounds good at idle starts up fine but when im on the throttle under load it almost crackles and sometimes bucks. I thought its was injectors replaced them all with stock ford remains but didn't fix the problem. I have AE and it passes a buzz test but i did a KOER test today and it started what seemed like a misfire during the test my ICP went to 2400-2500 and my IPR was at 38%. I have already put a new hpop in a couple month back along with new hpop lines do to a burst, ICP sensor, and i rebuilt the IPR valve. Not sure if this is a problem with fuel or the hpop I have also cleaned the screens in the tank and replaced the fuel pump which were pretty bad....
