Ford 7.3L Power Stroke (1999-2003) :: Turbo Whistle Under Hard Pedal Before Shifting
I have a 01 7.3 F-350, 120000. I rarely get down hard on the go pedal but a while back I did and heard at pressure whistle just before it would shift. I thought a bad turbo hose so I replaced them all. 'While working on the hose mounts I cleaned up the castings for a better seal'. The hose replacement seemed to get the running but the whistle is still there. I am thinking a leak on the manifolds for the Y-Pipe connection OR does the turbo have a release valve that can make a whistle sound?

I have a 99 F450 bucket truck. I was up in the bucket when the engine died suddenly. It turns over but won't fire. I have no dash warning lights now either but everything else seems to be working. Lights, radio, annoying beeping sound from the key left in the ignition, etc. There are roughly 5 or 6 fuses in the panel to the lower left of the steering column that don't have power to them. Are they all supposed to have power when the ignition is on? I checked the fuse panel under the hood and all of the fuses that have 12V to them are good. There are a few small ones that don't have power to them but I don't think they do all the time.

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..

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.
Ford 7.3L Power Stroke (1999-2003) :: White Smoke Blowing / Smells Like Fuel And Loses All Power
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) :: No Throttle - Check Engine Light Came On When Pedal Is Depressed
I have a 2002 F250 4x4 Powerstroke with Automatic. I have been having off and on issues for months with the throttle going dead. This only happens when I start it, if it works when started it will continue working until a different start session.
I have replaced the pedal several times before learning how to check its output with a meter and am quite sure that is not my issue at this time. However, when the pedal is depressed the check engine light lites up and nothing happens.
I am thinking it must be the computer itself, but was told there is another sensor or module under the hood that could cause the issue also which is several hundred dollars to replace as would be the computer.
Is there a way to test the computer, and what is this other module/sensor if it exists that could be the issue? Unhooking and rehooking the battery to reset the computer is no longer working to buy me a few more weeks, is there a simple way to reset the computer to try?
I love this truck when the throttle works but I am getting tired of paying on a truck while having to borrow a vehicle to drive to work.
Ford 7.3L Power Stroke (1999-2003) :: Truck Will Accelerate Quickly With Slightest Touch Of Gas Pedal - Service Engine Soon Light On
So about 3-4 times per day, my truck will accelerate very quickly with the slightest touch of the gas pedal, then followed by the service engine soon light...I checked for any codes to see what I may need to fix, but no codes are found.
What this could be? I am also having issues to where I a few times per day I have to put my truck in neutral to get it to start instead of in park...could the two be related?
Ford 7.3L Power Stroke (1999-2003) :: Died Suddenly When Going At 60 MPH
I am a cummins owner who just got a 2002 7.3 last week. It drove great for 200 miles then suddenly died last night going 60 mph. It sat overnight then started up and drove 10 miles then died again. I changed the cps and still no start. I changed the oil and let it sit overnight and it started this morning and idled for 5 minutes then died again. I have tried unplugging the ipc and still same no start situation. I plan to check the hpop level today to verify it is full. I also checked the nut on the ipr and it's electrical connection.
I am just a shade tree at best and would love some direction on where to look. I don't have any scan equipment to check pressures. Am I correct in thinking it is a bad ipr?
Ford 7.3L Power Stroke (1999-2003) :: Running Rough And Had No Power / Died While Driving
Well, I was headed out from work this morning, on my way to fill up as I was a bit below 1/4 tank.
Truck was running good, like normal, until after 5-6 minutes, when it started running rough and had no power. Worried, I pulled off the side of the road. As I did so, it died, and wouldn't start again.
I whipped out my phone, pulled up TorquePro, and ran a code check. Nada. Well, it sounds to me like it's not getting fuel possibly, so I figure the best way to check, is to drain the fuel filter bowl, and crank it some, and check the bowl. No fuel in bowl.
Wifey came to pick me up with the can of diesel I keep for starting my forge (had 3 gal maybe?). Poured it in the tank, cranked it, no start. Still nothing in the bowl.
I'm taking her to work now, so she won't be late, then I'm headed back with a full can of diesel.
If that full can still won't get it, should I keep shuttling diesel cans, or should 8 gal or so be enough to get it back to the fuel pickup level? And if it's not fuel level, what else should I start checking on the side of the road?
Ford 7.3L Power Stroke (1999-2003) :: 2002 F250 - Truck Lost Power Then Died - No Codes
I have a 2002 F250 Super Duty. Was driving it and it started to lose power and shut off. Then wouldn't start like out of fuel. No engine light no codes. Truck has 155k on it. So just because I replaced fuel pump. Truck runs but not right it's ruff no power kinda back fires in exhaust. I check wires and plugs under valve covers all seems ok. I ran truck and pulled each injector loose and engine would stumble. As in they are working. I replaced cps. Just because still the same. Then the truck started running right. But the truck runs but has knock but knock goes away and truck has full power. Yes oil is full and I change it regularly. The problem is off and on like electrical.

I have a 2003 F350 SD FWD Dually With 4.10 Axle Ratio. I'm looking for some front rotors and pads and I'm looking for recommendations. I tow a 44' Goose neck racing trailer on a regular basis so I dont want autozone crap rotors that are going to warp in a few thousand miles. I was on rockauto.com, they have Wagner, Bendix, Motocraft, Powerstop, etc etc. I thought maybe those Powerstop drilled and slotted looked interesting, but I dont know much about them.

i just bought my first diesel truck, a 7.3 of course. 2002 f350 4x4 crew cab, short bed. Any ways i drove it for like 2 weeks and left it at my uncles house so he can use to go to work. then 2 days later he calls me to tell me that the truck shut off while driving just like that. he tried turning it on a couple of times and it would just crank. he gave up and had it towed. I have been looking through all power strokes forums and found some solutions like changing the CPS or the IPR.
View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: Truck Died Like It Was Out Of Fuel
Jumped in the 1999 cc dually 7.3 6 spd superduty.
Just rebuilt the rear locker ( FYI if you use new clutches Do NOT add clutches, it is TOO tight now) and rest of rear end.
Full of fuel, drove it half the day only minor issues. Cruise, Horn, 4x4, suddenly would not work, but it was running and driving like it always has.
Around lunch while at 55 mph it shuttered hard like it had stalled for a second. I stopped and checked the oil. It was just above the add but I topped it off and went one. The further I went the more it happened.
So I decided to head back to shop and switch it with the car i had left there. It finally died like it was out of fuel.
next day I take 5 gallons of fuel and put in it ( maybe the gauge is acting up like the horn, cruise and 4x4?), it brings it from 3/4 plus to full mark, so gauge is working accurate. I also keep a fuel log that says i went 100 miles since last fill up.
Get in, it fires right up. I leave it sit and idle while i park the car. About 5 minutes and it dies. It will start run a few seconds and die again. The more I try it the shorter time it runs.
Finally does not want it start at all. I read about disconnecting plug on inside left front of valve cover , that had not effect. Crawled under, and frame mounted fuel pump is running.
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Shudders Then Died?
I have had this truck for a few weeks. I do not have a good history on this truck. the guy I got it from did not seem to know much about it. He got it from a local retired painter. It has 230K on it. It seems to run and start OK. So I got up and decided to take the truck because I'm trying to determine if it reliable or not. Its about 45F. It starts fine and idles fine I'm cleaning the windows.
About the time I'm done the idle speed slows sightly it shudders a bit and stops! I try to restart is a bit. No sign of life I take a car to work. After work it's about 68F, I open the fuel filter to check for fuel. That makes a mess! I clean it up the mess and she fires right up. I take her for a little spin everything seems fine. The CEL never came on. What do you think? I figured fuel from the way it died, but after work she fires right up. I do not want to get stuck on the way to work!
Ford 7.3L Power Stroke (1999-2003) :: Just Died Then No Start And No Oil Pressure
Ok so this past Saturday I drove the truck about 40 miles round trip to get fuel and came back to the house to pick up my tux for a wedding I was in that afternoon. On the way to the wedding I went about 10 miles down the highway doing about 65-70 mph and all of a sudden I heard the engine just shut off. No stutter or anything.
Went to restart and nothing just cranks. had to call and get a tow back to the house real quick and grab the excursion and head to the wedding. When I got home on Sunday I hooked AE up and started to poke around.
RPM around 150-170
Batt Voltage 11.5-12
IPR up to 65%
ICP 0 (have tried to unplug and start) (sensor is dry no oil bleed through)
Buzz test is good all injectors are strong. I am sure it is the lack of oil pressure but I dont know why. I can get more info from AE if needed.
Ford 7.3L Power Stroke (1999-2003) :: Truck Just Ran Rough And Died
So there's no signal/ electrical feed to the passenger side cylinders. I ohmd all the UVCH and they check out. Moved the wiring harness around near the big black multi pin plug under the air intake to the turbo and the passenger bank kicks in and out so it's definitely a wiring short. Need links and pics to that multi pin plug to troubleshoot the wiring.....

So I'm on my way out of town, when the truck just doesn't feel right. I proceed to make a u turn and pull off the high way. During the course of the u turn the truck shuts off. I pop the hood and notice the oil is everywhere from the fuel bowl back. Oil is also dripping off the passenger frame rail.
There is also a nice size puddle of oil pooled under the truck. I believe that I blew the high pressure oil line that feeds the injectors. I had to get towed back home. If it is the high pressure hose, how much does the stealership normally charge?
Ford 7.3L Power Stroke (1999-2003) :: CEL On - Long Crank / Truck Starts Losing Power And Eventually Died
On the way to work, the truck seemed to have a miss at idle and the CE light came on. Long crank to start leaving work, and truck starts losing power and eventually died. No smoke while it was losing power. Towed it home and checked the fuel pump and lines for blockage and found nothing.
2003 7.3 F-250 430K miles
strong cranking but no start no smoke out exhaust
Oil changed recently
IPR changed
Both UVCH gaskets and pigtails have been repaired.
ICP sensor and harness changed, also disconnected no change in cranking.
fuel filter changed today (no oil in bowl)
3/4 tank of fuel
dash gauge for lpop goes up to normal range during cranking and oil light turns off.
WTS light comes on and turns off as normal
tach gauge moves up between 100-200 during cranking
fuel pump turns on and pressurizes system like normal and turns off.
Ordered AE for the truck, and it directed me to the passenger side bank high open. Fixed the harness on that side and still nothing.
Sent off the IDM and it passed with flying colors
So now i'm leaning towards the HPOP, but would hate to fork over the cash for it and still not get anywhere. I'm going to take the valve covers back off and check the discharge ports for the injectors tomorrow.
