Ford 7.3L Power Stroke (1999-2003) :: Truck Has Lost Power Towing And Is Now Starting To Miss A Little


Jul 28, 2015

I want test my fuel pressure. What is a good gauge or kit to buy? My truck has lost power towing and is now starting to miss a little. I'm wandering if i my problem is in the tank. Is there a good scan tool that would diagnose things too?

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.

Ford 7.3L Power Stroke (1999-2003) :: Miss Causing Truck To Shudder

Took the beast out for a good road trip to try out the new tires. She is running good now, but has picked up a weird miss which cause the truck to shudder. It does feel and sound just like a miss, I know that it is a diesel but that is only way to describe it.

When driving along with the cruise set at 75, when I hit a hill, the truck will gradually accelerate, and it will miss a beat. Just like you turned it off and right back on very fast. Usually once, twice if the hill is long. If I accelerate harder it will not do it. Most often does it while gradually moving accelerator.

Has new fuel filter ad cam sensor.. Runs great the rest of the time.

Ford 7.3L Power Stroke (1999-2003) :: Noticeable Miss And Lots Of White Smoke When Starting

1999 7.3 misses when starting it cold (first start of the day even when outside temps were around 20 deg C ). It has a noticeable miss and lots of white smoke. After warming up it runs perfect. I changed the GPR and tested all glow plugs, 3 bad and one weak one all replaced. Now that it is cold out it still misses when first started, even if left plugged in.

It will start and run for approx 3 seconds perfectly smooth then it starts to miss and idle speed slows down. on one occasion I went to start it after sitting 10 plus hours plugged in and it started then missed and slowly died. Would not re start, It was firing and smoking but not enough to get going again. Went back the next day and it started and ran fine for a few weeks. Did the same thing to me yesterday, started and then petered out and died and this time it will not re start after 2 days of trying on a couple occasions. I changed out the CPS with no luck.

Ford 7.3L Power Stroke (1999-2003) :: Lost Fuel Pressure Going Down The Highway And Truck Died

Last night when i left work I noticed my fuel pressure was running about 77 psi, it normally runs about 68psi. today I took my daughter to practice and it was around 83psi, on the way home it was up to 95psi, so I parked it and took another truck to work.

About a week and a half ago I lost fuel pressure going down the highway and the truck died, finally decided my pick-up foot must have come off and had my sister in law bring me some diesel and it has drove fine ever since. (it was right at a quarter tank).

I have the FRX from riffraff and am thinking some pieces of that foot have got into the fuel bowl and plugging up the return. Things to check? Could it be a problem with the fuel gauge or wiring, and how to test them. It is an autometer gauge from riffraff.

It will probably be a few weeks before I can do much more than clean out the fuel bowl. I don't have anywhere inside to work on it and it's been rain/sleet/freezing rain/snow for the last 10 days. I have most of the stuff to do the hutch mod and its next on the list but was hoping to put it off till spring.

Ford 7.3L Power Stroke (1999-2003) :: Truck Not Starting When Cold / Would Not Crank Up

I had issues with my F250 cranking last winter when the temperature dropped, so I changed out the glow plugs in the spring. I hadn't been able to truly test them yet, since it hasn't been cold, but the other morning my truck wouldn't crank up. It was 40 degrees out the night before, and it had been almost 24 hours since I cranked the truck, but it seems to me like the truck shouldn't have an issue in that mild weather.

I'm not sure what I need to do next to try and fix this problem, it's been driving me crazy and risks stranding me if I park for a while in an area where I am unable to plug by block heater in. The truck cranks fine when I have had it plugged in for a while, so I'm fairly certain it's a heating issue. I haven't done any tests since last year, but I know that the GPR was working properly last winter, which is why I changed out the glow plugs.

Ford 7.3L Power Stroke (1999-2003) :: 2000 F450 Truck Not Starting

I have a 2000 F450 with a 7.3. I am having problems starting it. Batteries are good, engine turns over strong. It has started a few times after a extremely long crank (so long I am sure I am burning out the starter). I have replaced the CPS since it was cheap enough but that didn't make a difference. I have unplugged the ICP and it is very oily inside the connection. Does this mean the ICP should definitely be replaced? The truck will not start with the ICP unplugged. Should it be able to start with the ICP unplugged? Other items I plan on looking at at the IPR and possible the IDM box. Am I on the right track?

Ford 7.3L Power Stroke (1999-2003) :: 2000 - Truck Not Starting - Water In Fuel

Okay a little update on my truck not starting, and for those who have not read my earlier post. My water in fuel light has been on in my truck for probably a month of use. I drained the water sep under the truck nonstop and added several bottles of water remover and the light would not go out so I assumed the sensor was just bad. (im new to owning a powerstroke btw) I broke down coming home from work, got it towed home, and still cant get it started. It will crank fine just wont fire up. I tried unplugging the ICP, i replaced the CPS, and ordered a new water sep/ fuel filter for under the truck. And the fuel filter on top was just replaced a month before breaking down. Every single time i drain the separator tons of clear water diluted fuel comes out before it turns greenish.

Not sure if this could be a cause of getting water in my fuel but one time i filled the truck up completely and it was like the water overfilled and probably a quart or two of fuel spewed out onto the ground. Not sure where it came from. Also I have just over a quarter tank so i was thinking maybe the float broke and I just needed to add fuel but today before i went to add fuel i drained the sep and tons of water came out... Im so worried about hydrolocking my engine or ruining my injectors. But I dont know if my issue even is water related if the sensor just went bad...

Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - No Power Especially While Towing

I just bought a 2001 F350 diesel with 120k miles on it a couple weeks ago. Friday I headed out to Oregon with my 16 foot enclosed trailer filled with jet skis (about 4-5k pounds) for a competition. A few minutes after being on the freeway I noticed the truck did not have good power. About 30 min later while climbing a steep grade the truck almost went dead.

I started at 60mph and by the time I got to the top i was at 15mph with the throttle pinned. the motor sounded funny and shook the truck more then normal. After wards on the down side of the grade the truck started to act normal. I took it to my buddies house and switched trucks because I didn't trust if for the 13 hour drive.

Today I talked to a mechanic at the dealership and he said that it sounded like injector o-rings to him. I went home, pulled the valve covers and started the motor to see if anything is leaking. steam was coming from the valve area and the down spouts on the injectors was flowing oil. The thing that looked especially abnormal was one of the injectors looked like fuel was dribbling from it. I don't know if that is a problem or not. I couldn't tell if it was fuel or oil but no other injectors had fluid coming out near the wire connections.

Ford 7.3L Power Stroke (1999-2003) :: 2000 - Power Loss While Towing Up Hills?

I pulled with my 2000 F250 7.3 for the first time yesterday pulling a 12,500 5th wheel and then again today with an 18 ft ski boat weighting around 3500 for both the trailer and boat. I had this same issue pulling both.

Today when pulling the boat/trailer i was behind a slow moving truck and when we hit a hill with a passing lane i merged over and wanted to start passing him. We started off at around 45 mph up the hill and as I started pushing the pedal I wasn't gaining any speed and my rpm's didn't even get over 1500. It felt like a stall and continued that at around 45-50 mph up the hill (about a 65 degree slope). When I'm not towing the truck runs great, plenty of power and averaging around 16 1/2 mpg.

Only mods i have is a 6647 Napa filter, muffler delete and it's running the same 4 position TS tuner from the original owner. During normal operation I run it at the 75hp gain and when towing i use the 50hp gain.

In both instances i could see black smoke coming from exhaust when pushing the pedal but my rpm's wouldn't go up and truck maintained the slow speed going up the hill. Once at the top it drove normal and picked up speed without any problems.

Ford 7.3L Power Stroke (1999-2003) :: 2001 F250 Truck Has Always Had Difficulty Starting Cold

2001 F250 7.3l 294k miles

Ok so truck has always had difficulty starting cold since I got it about 12k miles ago. Replaced glow plugs, that made things slightly better but still no start unless temp gauge was in that first line above the C. Changed to Rotella, immediately after oil change starts better and at slightly colder temps.

Since getting the truck when you turn the ignition on you can hear a 'whistling' type noise which I believe is the fuel system pressurising. That used to last as long as the chimes did when you first turn the ignition on. More recently it lasts a lot longer.

Towed recently and had intermittent check engine light - believe this could be HPOP related, haven't checked codes yet as we're on vacation. No oil in the valley. But I do have a little oil carry over in the turbo intercooler pipes.

Truck slightly sluggish at setting off initially and then picks up reasonably well when not towing but my Dyno says I'm putting a bit more pedal to get the same performance from say two months ago

Pretty sure injectors haven't been changed since truck was new but can't be absolutely certain as there is no history. I was surmising this is probably both a HPOP and injector age issue but only from what I've found searching...

Ford 7.3L Power Stroke (1999-2003) :: Truck Is Starting Slow And Dragging As If Batteries Going Bad / Code P1247

Got two brand-new Motorcraft batteries installed about a month ago and truck has been cranking great. However, the last couple days in the mornings the truck is starting slow and dragging as if the batteries are going bad. It does crank pretty quick but just has a noticeable starter drag now. Since I have no way of diagnosing the batteries with a tester over the holidays.

What are the odds that brand new batteries are going bad? I was thinking this is a starter issue since the drag is most prominent in the morning but it does it throughout the day while I'm driving driving on each start. But it's not as bad as the first start-up.

I hooked up a scan tool (Forscan and Dash Command) and the only trouble code I received that something to do with the turbo boost pressure fault, it was a code P1247. I don't see how a turbo boost pressure fault, low pressure, could have any starting related issues but you never know. Just a note this code only came up on my FORScan Lite app but it did not come up on the dash command app so I'm not sure if it's a legitimate code.

So I'm back to a battery or starter issue. Is there a way that I can check without much equipment to detect whether not I have a starter or battery problem. I do have a battery charger but no other equipment.

Ford 7.3L Power Stroke (1999-2003) :: High Pitched Squealing / Scraping Sound - Loss Of Power Towing Uphill

Towing a 5th wheel at about 10,000 lbs total. Towards the end of out 9 hour trip home and going upgrade the truck begins to loos power and the engine starts making some bad sounds. Although its hard to hear it starts about 45 seconds in and continues later when going uphill. the truck also made a very high pitched squealing/scraping sound (not a belt) like it may have been coming from the turbo. Oil temp was about 220, trans temp at 170 at the time of the event.

Truck has 216k, stock, upgraded trans cooler, original fuel pump.

Ford 7.3L Power Stroke (1999-2003) :: All Power Lost / Engine Shut Off

So on my way home today I lost all power, the engine shut of and i coasted to side of the road. Went to try and start, nothing. When key is in the crank position the gauges were jumping all over the place, also accompanied by a lot of clicking from behind the dash. Nothing happened when tried to crank. No power to windows or even emergency flashers.

So i get it towed home, and of course it turns over. But this only lasts about ten seconds, then dies. I could do that a few times and then back to no power at all. Even at times with the keys out of ignition it will still click and make a lot of noise.

Ford 7.3L Power Stroke (1999-2003) :: E350 Lost Power / Shut Down And Won't Restart

My 99 E350 with 7.3 power stroke quickly lost power while on the highway today, bogged down and died. I couldn't get it restarted so had to have it towed home. I tried getting it started at home but it just pumps out white smoke out the exhaust. I got it to fire and run for a minute on a mixture of starting fluid and wd40 but wont stay running. Some background info, I checked oil and it was low but still registered at very tip of dipstick so I topped off oil level and still no start unless I give it a mixture of starting fluid and wd40. Batteries are good and cranking fast. Truck has 355,000 miles but very little blow by and prior to this had plenty of power and didn't have to use the block heater to start it thru the winter even when the temps dropped down to 12 degrees in January.

One thing I did have an issue with this past year was an intermittent cutting out while driving where the engine would instantly shut off but as soon as I tapped accelerator pedal it would start running again like nothing happened, wouldn't even last two seconds and it was running again just like shutting off the key and turning it back on and when it would do that the "Wait to start" light would come on and gauges would drop like key was off but again it all went back normal as soon as I hit a bump or tapped the accelerator pedal and it never lasted more than a second or two and never had to pull over, just tap the pedal or hit a bump and engine would kick in and run fine so not sure if that's related to whats going on now or not.

Ford 7.3L Power Stroke (1999-2003) :: Lost Power Steering / Refill Reservoir?

I lost a hose in the driver side front wheel well this morning while pulling RV to a campground. By the time I got there and got the RV disconnected, I lost all power steering. I reconnected the hose using a zip tie and have a friend bringing me fluid to refill reservoir.

Is my pump toast now? Can I refill the reservoir and prime the lines and be good to go?

Ford 7.3L Power Stroke (1999-2003) :: 2002 - Loud Bang And Lost Power In The Transmission

Last year I did some major work on my 02. Painted it, new injectors, 38R, and once it was back together, the transmission went south in a month. Got a Ford reman HD4R100. Shortly after the install, when in reverse, the torque convertor would lock up when you stepped on the throttle. As soon as you let off the throttle, it would disengage. Thinking it was a tranny issue, got another one from Ford. This one has been in the truck for about 9 months. And it seemed fine until about a month ago. It started doing the torque convertor lockup thing in reverse like the last one, but not as often.

Then last weekend it did it every time I put it in reverse. Then yesterday, while pulling away from a traffic light, there was a loud bang, and lost power in the transmission. Once stopped, I found out it has manual 1st and 2nd, but nothing else. No drive, overdrive, or reverse. I personally believe something electrical led to these issues, and ultimately, the transmission failure. I know the truck is not stock, but I do not run it hard very much. When it went bang yesterday, I was not being hard on it. Where to look at what is causing this?
