Ford 7.3L Power Stroke (1999-2003) :: 2000 F250 - Codes P1247 And P1248 / Noise Sounding Like It Lost Air Compression For A Few Minutes
Jul 29, 2016
My pickup has 316,000 miles on it. It's a 2000 ford f250 7.3 powerstroke. I have always bragged how my truck can pull anything because it has alot of power. Yesterday when pulling a 28' travel trailer up an incline I noticed I didn't have much power and it steadily got worse. Now I'm at a crawl when I hear a noise sounding like it lost air compression for a few minutes then the noise stopped. I stopped and looked to make sure everything under the hood was still attached and everything seemed fine.
I got back in and continued very slowly a few more miles home. Gauge were all good, never got hot. I put a scanner on it and it threw two codes. P1247 and P1248. I haven't noticed any unusual smoke. This is my second ford I've owned and know that when weather gets cold you may have to plug it in. But this truck it doesn't matter if it's 100 outside it will not start without plugging in for at least 1 hour. I've replaced all glow plugs hasn't worked. So I am assuming this break down now has something to do with it. I really am starting to not like fords!

E99 Romps on start up and randomly dying. Bought this truck about 3 weeks ago. Previous owner mentioned he had issues with it getting hot and shutting off and not starting. Has new IPR, ICP and pigtail, I just put in a new fuel filter. Has 206k miles on it and is the 4R100.
The past two days after sitting all night I have been cycling the key twice and it hasn't done its romp. Typically when it does I can tap the pedal once and it goes away. This I could deal with but its started to die randomly while driving, never while cruising down the road. Its either just after starting it and rolling slowly or slowing down for a stop or to turn. When it dies, I can put it in neutral and it fires back up no problem. SES light usually comes on for about 10-15 seconds after but goes away.
Replaced the grey CPS that was in it with a dark grey one from RiffRaff Diesel. Got a Edge CTS2 to figure out the problem, the codes Im getting are P1280 and P1247.
The ICP pigtail they replaced they spliced on with butt connectors. I plan on pulling it to check for oil and make sure it does look new and redo the connections with solder then shrink wrap them.
I was told to check the IPR% under full throttle which I did and it never went higher than 36.7
The truck did start running rough around 45-50 mph and I did get a video of the ICP jumping around while cruising down the road.
Then I went through a drive through and the truck kind of hiccuped like it wanted to stall and the ICP went right to 725 PSI and idled up and stayed there until I started to leave.
Truck is pretty much stock, K&N air intake and muffler cut out and straight piped.
Here is a link to the videos I got :

e99 ICP steady at 725 PSI after acting like it wanted to stall. - YouTube

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.

Alright I have a 01 F250 with the 7.3L in it. Recently had the turbo rebuilt and all the surrounding gaskets changed as well as boots. All this was done around 1,000 miles ago. Runs great and I don't see/feel any issues, no white smoke anytime, little black when I turn up the tuner and really ride the thing but normal driving none. Problem is I have a pending P1247 code that after a few days will throw a CEL... I'm not sure what the problem is and have been searching the forum and people are mostly saying they get it but the boost drops or there isn't any at all and the truck my stall or bog down. I don't have any of those problems. Turbo spools up to whatever I want and I've never had it stall or bog or even get close... So what should I check? Also new to the site and diesels.

I own the above described vehicle; I'm at about 196k and I'm the original owner. It's a quad cab, 2002 7.3L with power everything. I believe it's the XLT package (it's not in front of me... I'm at work. CONFIRMED... XLT package).
Currently, it's the workhorse and back-up for the family, not my primary driver - luckily. I've had failure if the automatic door lock on the rear pass. door, and a sticky lock on the rear driver's side lock - they've both been in this state for at least the last four years, no problems beyond the hassle of manual manipulation of the door lock from the inside - otherwise no electrical issues really to speak of.
Three weeks ago, we went to the snow. I rarely use the 4x4, but found that I had to use it that day to get out of some mud - it worked fine, no issues. In addition, I also used the cruise control... something I do rarely, but have not had any issue with it either.
In exiting the area some hours later at the end of our day, I noted two things... the "door ajar" dash light was illuminated and did not shut off through the drive home, and the dome light remained on until the battery saver shutdown shut it down... quite some time (where normally a key in the column turned past the insertion would shut it off).
When I drove home I used the cruise control, as mentioned, and it worked fine.
In exiting the vehicle while at home, as soon as the door was opened the horn started blaring panic alarm style - honk, honk, honk, honk... - and when the batteries are attached, there is nothing that stops the honking, except the battery saver timeout. BTW... no key in the ignition.
I don't use the FOBs... the batteries were dead anyhow (and I moved the FOBs out of range of the vehicle).
Attempted fixes:
- Lubing the lock/WD-40, then shutting/opening the doors (no luck/no change).
- Pulling door panels, removing locking mechanism, removing door ajar switches (I don't know what they're called), manually manipulating the piston AND checking each with a multimeter. (NOTE: One "seemed" not to work properly, so I purchased one from dealer and placed it back... still, no luck resolving the issues overall).
-Checked the wiring looms supplying all four doors - no broken wires noted.
- Replaced the two vehicle batteries.
I'm at a loss and I'm hitting up this forum before I move forward...
I've read that there are issues with the VSM for this year's model, but I'm hesitant to purchase the module without further feedback from a tech. I've read some general posts about alarm systems (doesn't apply to me) and horn issues (but those were horn constantly blaring... not the intermittent horn blasts of a "panic alarm sounding."
I've heard that the GEM and clockspring could be an issue, but I have to look more closely at the associated problems (like recheck to see if the cruise works... door windows go up/down like some threads have mentioned...). I have also read that the door ajar sensor switches attached to the automatic locks could be culprit, as they may "work" when pulled out, but not work when they're installed in the vehicle.
Ultimately, what the cause to the panic horn beeping, dome light and door ajar instrument indicator being on.

Bad day for the 2011 yesterday. Pulling my TT home from a great weekend tailgate. Stopped at rest area for a bio break. While accelerating on the on-ramp back to highway speeds, I hear/feel a pop under the hood. Immediately pulled over, and did a quick visual inspection, didn't see anything obvious, nor was anything dripping. Proceeded back onto highway.
Torque Pro indicated a P0471 & P1247, however no CEL lit on the dash. Noticed turbo boost was zero/near zero, and power output was way down. All 4 EGT sensors indicating 1000-1200 degree temps the entire time. Was able to make it home at reduced speeds. Noticed an odor burning engine oil too.
Was afraid truck wouldn't restart, so took it directly to the dealer after dropping trailer at home. Seems as though this should be covered under the 100K engine warranty, and I am at 95K now, so the timing was good if it was going to happen.

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.

Comming back from hunting today my truck suddenly lost power and stepping on the accelearator had no effect at all. We were on the highway thru the mountains but on a fairly level stretch for a few miles. Managed to pull the truck and toy hauler over and the engine was running fine but stepping on the accelerator had no effect. The check engine light came on every time I stepped on the throttle and went out when I released it. It started fine but no throttle response. Switched around a bunch of relays and checked the fuses and still nothing.
Not liking my parking spot i tried to see if it would move down the road at an idle but it would not. Then I thought to try it in 4 wheel low and as the shoulders were soft it wouldn't move forward so tried reverse and went back a foot, forward again and moved a foot and a half. did this several times and all of a sudden the throttle responded, took it out of 4 wheel and it ran fine all the way home. What would have caused this? I was ready to call a tow truck which would have been several hundred dollar bills for where we were and with the trailer

00 F250 338k auto
No error codes or warning lights (Forscan verified)
No smoke out of the exhaust
No oil or coolant leaks
Have banging noise from the motor. When cold truck sounds normal, quiet. When it warms up, the banging becomes audible. You can hear it at idle. You can hear it under acceleration. Frequency increases with RPM
When at speed, and letting off the throttle, noise goes away.....comes back when back on the throttle. Any time during driving when I let off, engine quiets down to normal. To me it sounds like exhaust leak, bur not sure how to check for those?

I've got a99 F2 50 super duty with a 2000 2001 motor. I got the truck in the beginning of last winter so this is my first summer with it.
When I first got the truck there are injector issues with the truck. Since I fix the issues there has been little problems out of the truck however it's still suffered misfires when Cold but once up to operating temperature it was fine. Yesterday I had to go with a friend before leaving for the trip I checked the oil it was full and appeared normal the trip was about 150 miles. I came home park the truck after everything was done. This morning I came out started the truck everything acted as it should... truck fired right up everything was great went and dropped off my trailer at the yard come back got fuel when I come back out from paying for the fuel the truck took about 30 seconds to fire up I checked my gauges and torque pro and everything seemed normal. So on my way I went.
I drove about 10 miles on the highway to the place I had to be when I got done doing my business I came back out to start my truck and it did the same thing this time however it took longer to start I managed to drive about a mile down the road when I noticed my old pressure gauge flickering and my Oil pressure light on I immediately shut it down and coasted into O'Reilly's parking lot I check the oil in the truck and it was empty according to the stick I added two whole gallon.... With it filled back up down the road I went. So currently the truck is still suffering from a long hard starts it takes 30 to 45 seconds before it all actually fire up once it fires up everything appears to be fine however the truck is slowly smoking a bluish black color... It's never done this before however I've never had this truck in the middle of summer when it's real hot out I don't think this is normal.
The truck doesn't appear to be down on any power actually it, acts as if it might've picked up of some power it is felt real peppy today compared to other days. Also I might note that about a week or two ago I started smelling diesel like either really rich diesel or raw diesel wasn't too bad but I just got whiffs of it for now and then. Now there is a burn oil smell present from the exhaust. Like I was saying earlier when I first got the truck I had to service the injector O-rings... I was told that the miss firing when cold was caused by the Poppitz sticking. The misfire hasn't been present since it got a little warm outside like I was saying it was only when the vehicle is cold.... Just thought I would mention the injector issue not sure if it's relative or not..... My thoughts are it's back to an injector issue or O-rings or possibly did I wipe the motor when it ran out of oil. I am not aware of where the oil went as there is been no leaks or drips.

My f250 is having a stalling issue. It will run fine for about 5-10 minutes and then die out, already replaced CPS, fuel filter, and fuel pump. What else could be the problem?

i bought a f250, i rebuilt the 7.3 after installing it the transmission isn't shifting correctly. Reverse perfect, 1st and shifts to 2nd great. wont go into 3rd. i replaced the 2 sensors on the transmission, i replaces the sensor on the 3rd member. the speedometer works but not correctly, i can unplug the sensor on the front of transmission and it shifts into 3rd. but when i plug it back it doesn't. no codes. could it be the ecm?

I have a 2000 4x4 Limited 7.3 Powerstroke. 290k miles and runs like a top. However, if I don't plug it in for a few hours before starting she sounds like an old John Deere Poppin' Johnny. I had the glow plugs replaced yet had to go back to the repair shop three times since because it threw a code each time. No codes now just rough shaking and vibrating start for about 5min (without plugging in block heater) or so then once warmed up she runs great.

On the way home from work today as I pulled in there was a pulsating under when I pressed the brake pedal and the ABS light appeared on the dash. It didn't pull to the right but it felt kinda odd. When I start the truck, the ABS light comes on with the other indicators, goes off and then comes back on a split second later.
Haven't had any issues lately, and haven't had it worked on lately so not real sure where to start. I checked the VSS sensor on the pumpkin and it was relatively new, which means the prior owner had replaced it. Master cyclinder is full of fluid. I pulled the codes and it returned P0603 P0671 P1670.
Just sprang up out of nowhere. The speedo was not acting squirrely, just the brake pedal pulsating intermittently. Is there a VSS computer I need to replace?

2000 f450, truck has been running great and then all of a sudden starts running really rough. I check the oil and its dry! it was 9 quarts low! i checked the oil 2 weeks prior as i often do. i change the oil every 4500 miles and now this. i had driver side injectors done about 5 months ago. I take it to my mechanic and he said he thinks it has low compression on 2 cylinders but didn't do a compression check( not sure how he knows). He told me to run it until it pukes , keep putting oil in it with lucas oil additive. Then i will have to have the engine rebuilt. The truck only has 175000 miles! i thought these things were supposed to run forever! Does this seem right to you guys? I bought the truck a year and a half ago and have always kept up with it. has dp tuner but everything else is stock. Smoke comes out of the oil fill tube slowly but doesn't send puffs like a locomotive. mechanic said the turbo is fine.

Ok, so I leave the fire station this morning headed home and my steering felt weird. About 1/2 mile from home I hit a bump and my drivers side front wheel started making a screeching noise. I stopped and looked out the window and it appeared fine. I limped home and as I pull in the driveway, I lost all my steering. I look under the truck and this is what I found.
Not sure what to do. This is my daily driver and neither of my 2 mechanic friends will answer their phones.

OK . So here's the deal. My 2000 7.3 ford f250 170k miles. Going from phx az to flagstaff az . For some reason I'm hitting about 40 miles per hour with the pedal all the way down going up a decent grade. Seems like something isn't giving the motor power. I'm pulling a 28 ft toy hauler pretty much empty . Under 5800 pounds . What this could be . Also was get pretty close to the red on water temp gauge.

I've got a 2000 F-250 with a 7.3. The other day I was driving down the road and it lost power and my foot almost went to the floor. I was at the bottom of a hill when it did this and I was running 60 mph. By the time I got to the top I was running 20 mph and had the truck to the floor. When I was driving it home it was tacking around 1800 rpm and my egts were only at 125 degrees. I know I'm not getting fuel. I thought it could be the fuel filter so I changed it. Still no luck. It'll start back up but it dies if I take my foot off the accelerator. It shook terrible when I was driving it home too. Is it injectors, uvch, hpop, or something else?

Cooler weather has arrived and my 2000 f250 won't start. Wait to start light is coming on, no power passing through the two relays on top of the engine. Are both of these for glowplugs? My 97 only had one. How do I diagnose relays on this truck? If you cross out the two relays truck fires right off so I know the glowplugs themselves are good.
