Ford 7.3L Power Stroke (1999-2003) :: F350 Running Bad When Locked Into First Gear
My brother is having a issue with his 99 F350 diesel automatic tranny pu. When in manual 1rst gear the engine stumbles and runs like crap. In drive or 2nd gear it runs fine. He's getting a code for a bad cam sensor. A new OEM and aftermarket sensor has been tried with no solution to the engine problem. What might be going on?

I have a 2000 F350 super duty 7.3 turbo diesel. It has 189 000 kms or about 150 000 miles. I have had problems all winter with my engine. I can drive it for days and then without warning she quits. She will not start right away but sometimes, if I drain the fuel filter and try her she fires right up and runs for about 10 minutes then quits again. If I wait a few hours, while waiting for a tow truck, she may start and again run for days but she may not...
I have a good friend who is a mechanic, and a cracker jack at it, but he is dumfounded as to what the problem is. She does not show any codes and my buddy has a computer analyser.
So far he has done what others have suggested including changing, Crank Sensor, IPR sensor, ICP sensor, new Lift pump, Fuel pressure regulator, and removed emptied and cleaned the fuel tank and suction lines.
All this to no success. Now we have run out of thoughts. All week I drove her without problem till yesterday when she quit again. There is no set time, weather condition or anything to suggest a problem so I reach out for a solution. The truck is in mint condition and very, very, far from being condemned but this is frustrating.
Ford 7.3L Power Stroke (1999-2003) :: Idle Roughly - No Power - Got Codes P1280 And P1316?
Started my truck yesterday and drove about 1/4 of mile and all of a sudden I lost all power but was lucky enough to creep back home. Had a friend put it on a scanner and it spit out P1280 and P1316 codes. My truck will start and idle rough but has no throttle response and no power. I changed out the CPS and ICP and the problem still exists. I got an infrared thermometer and checked the heat coming off each manifold and the driver side was reading about 200 while the passenger side was reading about 75 while at idle. Pulled valve pan cover off the passenger side to check and see if the harness came loose and everything looked fine. So my question is do you think this could lead to a bad IDM?

Lately I have been having problems loosing power. Truck wants to miss mostly going up hill and runs sluggish I'll pull off the road and let it idle for a minute and it will run fine. And it is only occasionally some days it don't happen at all and other days it happens quit often. New fuel filter, oil is good, had it on the scanner and isn't throwing any codes. Around 230k miles newer injectors.

I have a 2002 7.3 160k miles and recently it has been hesitating while cruising along at 35mph roughly. In park right off idle the engine does shake but if i give it a little more pedal the shake clears out. Not sure if that has anything to do with my issue but im just throwing it out there. Anyways cruising down the road the truck will hesitate almost like its not getting enough fuel the engine bogs then picks up then bogs and picks up but it i give it more pedal the truck gains speed and the issue stops and i can resume cruising at say 45 and not feel this hesitation at all.
On the toll road i never feel the hesitation cruising at 2k rpms. A problem that might of lead me to this issue was in the winter below 30 degrees i would drive the truck get to a stop light engine still cold or maybe warming up off the cold mark but when i go to take off from a light its like my fuel pedal doesn't work but the rpms will climb a little then the truck takes off and jerks really hard since i had the engine rev'd up. which made me think throttle sensor immediately or maybe the trans is having issues. since its warm out I don't have that issue now so i believe that it the trans. do you think maybe my hesitation now is also the trans? I never get a CEL. I did recently change the coolant temp sensor and now i am having this hesitation issue.
But I was told the ECM does not care about coolant temp on an auto truck so i dont see how that could affect my performance. Instead the autos monitor oil temp and the manual trucks monitor coolant temp correct? I had an issue like this with the truck years ago when i purchased it i was leaving the gas station on very cold maybe 10 degree day and the truck fell flat on its face and threw a bunch of codes but i let off the throttle and got back in it and it took off like nothing happened. So im not convinced the coolant temp sensor was defective from factory. But this old problem of not accelerating seems to be coming back to haunt me.... and i think its in a new form with the hesitation once in a while. I think i forgot to mention the hesitation isn't all the time!
Ford 7.3L Power Stroke (1999-2003) :: Turn Over For 30 Seconds After Cranking / Engine Starts To Run Roughly Then Die
I have a 2002 F-450 crew cab 2wd automatic 7.3 diesel with 298k on the body and about 120k on a Jasper engine. About a month ago I started it in the morning to let it warm up. Went to make coffee. Came back and it had died. It was low on fuel and I didn't pay attention. Played hell getting it primed back up. Now if I don't let it warm up for twenty minutes it won't run worth a flip and has been dying out. Changed fuel filter. Unplugged ICP. No change. When I crank it it will turn over for about thirty seconds then oil pressure gauge moves, then engine starts to run very roughly. It will die. I repeat a few times. It will eventually start and start and stay running. Blows whitish grey smoke until it warms up. No loss in power till CEL comes on. Still not too much loss. Sometimes it takes a long time to get it running. Sometimes it will die after I get out of the driveway if I don't let it warm up. Truck was serviced maybe 3000 miles ago. No water in fuel. New fuel filter. New air filter. It is a company truck. I work for a small company building cell towers.

I have a 03 F-350, 7.3L. There is a slow oil leak that only leaks after I've run the truck. In other words, it doesn't just sit and leak overnight. I'll park it after running, and the next morning I'll notice a small pool of oil, approximately 2" in diameter. The leak appears to be coming from the oil pan area. I degreased the entire oil pan area to get a better visual of where the leak is coming from. I can see oil trailing down the front of the oil pan and the rear of the oil pan. Does this sound like the gasket? Or, what else could it be? I'm praying its not as bad as I think and need to replace the gasket.

I have a 2003 F250 7.3L. I put new injectors in my truck four months ago and all of a sudden, I have 2 cylinders not working correctly, making the truck to run really badly. I sent the 2 injectors from the bad cylinders back for warranty and they replaced both of the injectors but nothing was wrong. I put them in and the truck still runs badly. I have a new fuel filter, new ICP, new CPS and glow plug relay. I cannot drive the truck, it smokes white at idle. I can unplug each injector at a time and cyclinder 5 does not change how the truck runs
View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: Loss Of Power / Rough Running
I have a 2001 ford 7.3l powerstroke diesel. When I first noticed the problem I was towing a trailer going up a grade and got into the throttle almost to the floor and noticed a loss of power and the service engine soon light flashing extremely rapidly a few times and never came back on. I made it home, still lacking power but not running rough. I drove the truck to work the next day and the truck was running rougher and loosing power. It ran great through lower RPM's but seemed to trip as soon as you gave it over half throttle. eventually the truck wouldn't run right at all and lacked complete power. It idled rough as well. My mechanic threw the computer on it and it said injector pressure reading too high or too low.
I was told to replace the IPR on the HPOP and I did. (I also replaced the fuel filter and changed the oil). After replacing the IPR it ran great, had full power! then it began to slowly die like it did before until it sounded like it was running off 4 cylinders again. I pulled the ipr out, cleaned it and changed the oil again. It seemed to clear it up for an hour and ran great but then began ran rough again. I also replaced the CPS sensor. I feel like its not getting enough fuel or something, im just wondering if it could be the ICP or the lift pump. There is no check engine light at all. Its just got me stumped because cleaning the IPR clears everything up.... temporarily.
Ford 7.3L Power Stroke (1999-2003) :: Running But Losing All Power
Where I should start? My 7.3 is running but losing all power. Pumping the fuel pedle will get it started and it will run for a few then lose everything again. Should i just drop the tank and check the sending unit and intake and filters first then work my way up?
View 5 RepliesFord 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) :: Rough Running / No Power After Just Driving A Block Or Two
I have had this happen twice now. Starts fine, idles fine, then either sitting or just driving a block or two it starts running very rough, no smoke that I remember seeing, and now no power. Barely makes it up a hill. The first time I thought is was related to the heavy rain the night before. I had the tow truck coming and decided to try it again, this was after a few hours sitting. Ran perfectly. The second time, no wetness/rain, pulled away from the house and in a block or two, same thing ... rough, no smoke, no power. Pulled back into driveway, turned off for a minute, restarted and ran fine. Ran perfect today. What is the best injector cleaner to use in the fuel?
View 3 RepliesFord 7.3L Power Stroke (1999-2003) :: 2002 F250 Idling / Running Rough And No Power
2002 F250 7.3L suddenly idling and running very rough, and doesn't have any power. Truck has been running perfect, it's my daily driver, and just put a couple hundred miles on it yesterday with no problems. I had been having some transmission issues when I tow heavy so I bought a new transmission yesterday. This morning I pulled the truck into my garage to change the transmission. Again truck ran fine, no signs of any issues before the trans swap. I changed out the transmission, which included unhooking the trans wiring harness from all the various sensors, and unbolting the starter.
I didn't mess with anything in the engine bay except for unhooking the batteries. I had also repaired the overdrive button wires, as they had been pinched in the steering column and the button wasn't working. When I got everything hooked back up I cranked it up to get the trans fluid flowing through the transmission, it started right up and idled good. I had it running for a few minutes and it was beginning to make a little more noise than usual. When I started to back out of the garage it was getting pretty rough, almost like it was running out of diesel. I put it in neutral and gave it some throttle and noticed I was getting white smoke out of the exhaust and could smell diesel pretty strong.
I checked my injector resistance at the valve covers and got around 4 ohms +/- on all of the injectors. I rechecked all of the clips and harness that I had messed with. I took a look at the ICP sensor and it has oil in the connector which I know can cause a rough running condition in some cases. It looks like it has had oil on it for a while. I unhooked the batteries again for about 20 minutes to try and reset anything that may have messed up. I checked a bunch of connections under the hood to see if anything was unhooked or loose.
I also cleaned up the connector on the ICP sensor. I started the truck back up and it idled perfect so I pulled it back out of the garage and headed down the driveway. It almost immediately started running rough again and barely had the power to go up a small hill. I pulled back in and tried unplugging the ICP while it was running, which made a slight difference in the idle but still very rough. I plugged it back in and the idle progressively got worse until it was chugging really bad. I shut it off after that and haven't messed with it again.
What might have happened? Could it be a bad sensor or transmission position sensor in the new trans? Is it just coincidence that this happened with a transmission swap? I am going to get a new ICP, but if there is anything else I can try/check before I can pick up the ICP on Monday let me know.
Ford 7.3L Power Stroke (1999-2003) :: Running Rough When Accelerate / Bogs Down And Looses Power
I was wondering if fuel injectors throw a code when it goes out. I have a 02 7.3 been running rough when you accelerate bogs down and looses power not sure but sometimes gas light would come on knowing I have gas in it could that be a sign of the sending unite and that's why it runs rough..
View 3 RepliesFord 7.3L Power Stroke (1999-2003) :: Won't Stop Running?
No start. Changed starter solenoid. Changed starter. Now it runs although when I turn the key to the off position and remove it the engine continues. The only way to get it to shut down is remove the small wire from the positive on the battery and then turning the key to the off position or vise versa. The machine seems to be pulling power even when completely shut down. The batteries drain power with "nothing on" i d m shot? Someone stop me before I go to the dealer.
View 5 RepliesFord 7.3L Power Stroke (1999-2003) :: Oil Running Out From Under Engine Across Floor?
I bought a 2002 body with a late 99 engine with lower miles a couple years ago. I knew it had an oil leak when I bought it. My other truck had a turbo pedestal leak. This truck has a small pedestal leak but it's not that much of an issue as there is little oil in the valley and next to nothing running down the back of the engine.
The other leak is getting worse. It has been leaking somewhere up front and coats the main steering arm off the steering box, the lower rad hose and the rest of the steering linkage. Last night after driving around 100 Kms I have oil running out from under the engine across the floor.
I changed the LPOP after thinking the front leak was from there. Unfortunately i don't think it was.
I am hoping it's the oil cooler and not the HPOP. One other thing is before yesterday's trip, I installed my homemade ccv mod off my other truck. I don't think the leak is coming from that either.
Ford 7.3L Power Stroke (1999-2003) :: Running Lights Not Working
A little background information is that I was towing a large gooseneck trailer about a year ago when half way to the destination the lights quit. Not just the trailer but the truck tail lights, turn signals and everything except the headlights. Well after getting there and unplugging everything it stayed the same. Well on the way home without the trailer the lights began working again. All the truck lights acted as it never happened. No blown fuses or anything.
Well things are are going ok since then but I can never get running lights to any of my 3 trailers to work. Turns and brake lights are fine. What gives? All the fuses are fine and the truck running lights work just fine. One thing I have noticed is that on my horse trailer I have the little led lights on the sides operational... I would have assumed these to be the same as the tail running lights.
Ford 7.3L Power Stroke (1999-2003) :: Truck Just Quit While Running 70 MPH
Traveling right now. Limited access to FTE.
On the way to the airport this morning at 4:30 am, the engine simply did while running down the interstate. Absolutely no symptoms leading up to it. Turns over fast but will not start. White smoke from tall pipe while trying to start.
I unplugged the fuel bowl heater and checked the IPR tin nut and the ICP sensor connections... Nothing obvious.
Problem was CPS and the engine is now running fine again.
