Ford 7.3L Power Stroke (1999-2003) :: 2002 F350 - Lack Of Power
Oct 7, 2015
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.

I have a 2002 F350 4wd with the 7.3. I was driving the truck and all of a sudden it was running like crap. the engine light was on. after a minute or so the engine light goes off and the truck is running fine. then again starts running like crap. I am close to the house so I limp it home. runs like crap.... will barley climb small hills. engine light is on. get home turn it off... next day... starts up and runs great for 10 - 15 min. engine light comes back on... runs like crap.... my neighbor says "It's the crank position sensor" I replace it.... runs great for a month.... now it's doing the same thing......

Long story short, when going up hill or any incline for the matter it feels like it's struggling and lugging, blowing carbon everywhere. It's an automatic so I yeah can downshift sometimes but even turning overdrive off doesn't work in a lot situations. My EGTs are way too high and I'm not about to tow my project car to OKC unless I get this figured out. I live around Salt Lake City so towing can be hard up surrounding passes. Just cruising to park city at 70mph on I80 up a pretty good incline my EGTs were 1,000. Just driving around the city, some hills I see 700-800 when I'm going 35mph.
At stop lights I'm seeing 400 at idle. My probe on the pyro is going bad starting to flutter but even if I fix that I'm still having issues up hills. Boost is good, up-pipes don't appear to be leaking but fuel pressure is a little low @56 and I know it's not the fpr because I just messed with that yesterday, put a new poppet and oring in, I haven't checked the fuel pump yet or dropped the tank either. If it is in fact fuel pressure related, does it make sense for me to see smoke coming out, wouldn't that indicate too much fuel? I'm lost, it's driving unloaded like I'm pulling an anchor.
Regardless of which spring I put in the frx I get 56psi, even with the black one I may see 58psi but even with 58psi it was still lugging it's butt off up hills and making that terrible drone sound like F you down shift me now.

Picked up a second 7.3, just finished installing the new transmission last night, took it on a drive last night, everything was fine.
Went to bring it home last night- and found myself unable to maintain 50-55mph on back roads at 3500 rpm.
At first it almost seemed like I wasn't getting 3rd/4th gear, but upon taking it for a spin with torque pro, I am getting all gears, overdrive works, TC locks- all appears good there. Trans is getting really hot- but I believe I messed up the bypass lines or the bypass valve is not opening correctly- not the biggest concern.
I let the truck cool to more normal operating temps, took it for a spin, same story. I top out flooring it at about 55mph. No fault codes other than my faulty glow plug module. Everything I'm monitoring on torquepro looks fine with the exception of boost. When I floor my other 7.3, I get 15-20 psi, this, I get like.. 4. Unplugged MAP, nothing changed.
Turbo shot? Glogged pipes? These are my first initial thoughts. Let me know if I'm going in the right direction here, I can rebuild a gas motor in my sleep, but diesels are a newer animal to me, I've only had them about 2 months.

I have a 2004 f350 with a 03 bullet proofed motor. The truck did not have any power and the turbo wouldn't support until I put a new vgt solenoid in and it ran great for about 3 miles... Stalled doing 65 kinda lacked power while accelerating but got up to speed quick. I pulled over and no start. It is running error code kam on pcm from disconnecting batteries but could this cause the stall and no start? Or should I be looking into icp sensor?

I have a 2002 f350 dually with a 7.3 and 197k. At 186k it died while driving and I had it towed home. As soon as the tow truck dropped it the truck fired right up like nothing was wrong. Then it died again 2 days later. I replaced the cps, but the fix was replacing the icp and pigtail. Now it is doing the same thing again. It died on my wife while driving yesterday, i had it towed to the dealership I work at and it started and ran for about 2 hours with no issues.
I hooked up the factory IDS and had a diesel tech look at it with me. The oil pressure, injector circuit and injectors, and IPR all look good. The batteries were a little weak so i replaced both of them. I drove it home yesterday, about 10 miles, and drove it around town today. Then i tried to jump start my 96 bronco and after about 10 minutes of running it sort of hick uped then 5 minutes later it died and would not start. I let it set for 30 minutes and it started and died after about a minute.

2002 F350 7.3 intermittently wont start after I've shut it off, it runs fine but sometimes won't start when it's (warm)? Wait hour or more and it starts right up.
Is there something I can look for before I bring it to a mechanic?
Just to clarify I am a gal with little wrenching skills but I can look at videos and follow directions if it's not too involved.

2002 F 350 7.3 4x4
Aftermarket gauge will climb to 250 after around town driving of an hour or so or multiple trips within the hour. Not towing. 160,000 miles on odometer. Changed trans fluid at 40,000 mile intervals. Most recently about 1500 miles ago. Most recent change using Mark K's method. Was getting fluid from rear port when I changed fluid. Blew out oil cooler and there did not seem to be a blockage as flow was sufficient.
Still overheating according to autometer trans gauge in test port. No codes retrieved using auto-ingenuity also O/ D light is not flashing. Would like to run torque converter slip test using AE according to wooden things method but TC slip desired and transmission gear ratio is not available under that name in live data meter. AE just updated to most recent version.
I purchased a new tranny oil bypass and will install soon. Also purchased a new 6.0 cooler to replace stocker but am hesitant to install if tranny is failing because I am concerned that the new cooler will just get some blockage from a potentially failing transmission and I will be buying a new cooler along with a BTS rebuild.

I'm trying to figure out what axle I have on a 2002 f350 single wheel 4x4 so I can order a replacement seal. So this morning I got to work and noticed that am oily guild was dripping from the front of my rear differential where the drive shaft hooks into it. I figure it the seal, so when I went to look up the repair kit they list several different axle options because of gearing, what axle I have as there wasn't a in owners manual with the truck. Who can I find out what axle I have so I can buy the repair kit for it...

I finally got my 02 F350 running again after replacing the Fried PCM, but during some additional shop prep work, I discovered that the engine dies when you use the horn button, it will start right up afterwards so no permanent damage, but, Where to start? I have Forscan and a cable so I can get into the PCM but I need to know where to look or what PIDS I should be watching during troubleshooting.

I have an 02 F350 7.3 ... I just installed my glowshift tripple gauge pillar set. I have an EGT, Boost and fuel pressure gauge ... I followed all the constructions on installing them. The boost is working just fine and the EGT was too, but after a while the needle started going back and forth and the red warning light what blinking and then it just sat at 0 with the warning light on and stay that way. My fuel pressure gauge is connected to a sensore i put in my fuel filter housing, my fuel pressure gayge right from the start stayed at 30 psi with the red warning light on and just stays there .... Also the buttons to change the color and set the peak on the EGT gauge are sticking for some reason and staying down and aren't letting me change the color ...

I have a 2002 f350 7.3. It was running fine 2 days ago. After I put some diesel in it my water in fuel light came on. I drained the water out and took all the fuel out and put fresh diesel in it. It starts up fine and idles okay but when I try to drive it it looses all power and acts like it's starving for fuel and almost dies. It was smoking white smoke for a little bit even after I took all the water out but now it's black. What it could be.

I'm new to diesels and I've got a 2002 F-350 w/7.3L 224K miles. I've had it for about a year and had no problems. Burned a little oil, about a quart every 1000 miles or so, but in the last two weeks it's gone through the roof. I have gone through roughly 12 quarts in 300 miles. I see a lot of blue smoke at start up, and it's being harder and harder to start in the cold. From what I've read it could be several different things, and I plan on doing the CCV delete and changing the orings on the injectors just for good measure. Is there anything else that I might check as well, or am I completely off base on what it might be?

I have an 02 f350 7.3 power stroke...Yesterday I noticed the outside temp was reading wrong,it was jumping from 67 to 86 to 92 back to 67..Temp was prob around 90 with high humidity and my a/c was on..So I got to where I was going and when I restarted my truck to go home the fuel gauge dropped to empty(I just fueled the day before) and fuel light came on and outside temp still wrong on the overhead digital display...Are these two things related???
Stopped the truck restarted it and fuel reads correctly again....Went out today and fuel light back on and on empty...Outside temp wrong again,a/c is on .....I disconnected the batteries when I got home to "reset the system"if there is such thing, fuel gauge working but outside temp wrong..?? Where is the outside temp sensor ?could condensation be running onto the sensor and throwing off my temp gauge? Just strange that both these things happened at the same time......I don't think its a fuse or they wouldn't work at all. I should mention all the other gauges work correctly...

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 ....

2002 F350 single wheel 4x4, 280k miles chipped with a 6
My problem first started when the bottom of my sending unit broke off in tank causing me to run out of fuel at 1/4 tank. I dropped tank and repaired. A week later I noticed fuel dampness on my tank and discovered I crossthreaded cap on sending unit. About this time I started getting a shutter at slight acceleration only and a harder hit at idle. I thought air in lines so I dropped tank and reassembled. No air in line at all now but I still have a shutter so I replaced fuel filter in case of obstruction. No luck. Now since I have owned truck it has been a pain to crank in cold weather if it wasn't plugged in over night. It has been hard lately even in moderate weather since shutter started so I replaced both batteries today.
I replaced the ICP today also because I noticed the other day when there was oil on and around harness to it and when I unplugged it today the truck changed idle and there was oil inside. After I changed it I took it out and it still had the shutter and sound of a miss. At about 8 miles in it just died going down the road. I coasted to the side and it cranked right back up and drove home. The shutter doesn't fill as bad but there. Also I live in the mountains and on my way home after cutoff I had chip in Stock position and had to put peddle to the floor to climb hill. I've never had to do that. I'm getting worried I work for a living and caint keep throwing money at it aimlessly. I'm thinking at this point IPR or CPS. But I'm no mechanic so I could be completely wrong.
