I'm stuck how do I test the idm all the fuses are good and the relay is good I believe I switched with another one... 341,000 miles I love this truck .....
View 2 Replies00' 7.3 is acting a little strange lately. i was towing a 15 foot trailer the other day for about 250 miles that wasn't all that heavy and my foot felt like it was very close to the floor. I had it to the floor and the truck would only go 60. now even without that trailer its better but still i feel as if i have to really put my foot down into it to speed up. if i go all the way to the floor in o/d it'll downshift and start speeding up but very very slowly then i run out of pedal and am at the floor, a lot slower than before. Before i wouldn't get to the floor and id already be moving pretty good. but now i gotta keep it pretty much 3/4 way down and keep it there to get up to speed and stay there. truck has 253k no tuner or programmer just 6637 intake and an exhaust, ww2. leveled on 35's. the tranny isn't slipping or at least doesn't seem to be. She doesn't shift perfect but its not anything crazy bad for stock with 253k on it. maybe something wrong with the actual pedal? or hopefully not but maybe the trans or motor , or maybe a sensor or something?
View 14 RepliesI purchased a 2000 excursion with the 7.3 a couple of weeks ago. The guy said originally in the add that it need #2 and #8 injectors replaced. When I went and looked at it he had already replaced them and said the it still has no power and needed the remaining 6 replaced. I purchased it as it was a good deal thinking I should be able to get it fixed for worst case a set of injectors. BTW the engine has little to no blowby and starts easy and idles great.
The problem it it will not build any boost (has external boost gauge). Actually the gauge only shows vacuum. With the truck in park or neutral you can slowly rev the motor to 2500rpm and all seems fine but as soon as you break past 2500rpm it sound like it is missing and starts blowing white smoke. The smoke smells like when a diesel heater runs out of diesel. If you try and drive it it has NO power and will not move out of its own way and will eventually start like it is missing and blowing white smoke.
The previous owner replaced the following:
#2 injector
#8 injector
UVC gaskets
MAP Sensor
Wastegate solenoid sensor
The first thing I did was start looking at the no boost issue and pulled the turbo. I deleted the EBPV while i was there. Also the turbine wheel was in very bad shape so i replaced the turbine wheel, shaft, seals, bushings and installed a new compressor wheel 5+5 wheel off ebay. Reinstalled turbo and the symptoms are the same. I also replaced the clamps on the spider with Tbolt clamps instead of the worm gear styles and it psi tested all piping and intercooler to 30psi with no leaks. Also the up pipes have already been replaced with the bellowed style so there are no leaks and it has a 4" straight exhaust.
I have since ordered oring kits for the injectors and also ordered the fittings for the fuel bowl so i can check fuel pressure. it has a new air filter, oil filter, oil and fuel filter installed.
The ICP sensor has oil in the plug but if i unplug it the symptoms are still there.
I have also used a scanner and the ICP pressure is approx 500psi at idle and the duty cycle is about 11% at idle. Also the HPOP looks to be new as it is very clean compared to the surrounding parts and i have checked the HPOP reservoir and it is full to withing 1/2" from the threads.
2000 Excursion
7.3
205000 miles
I am assuming that the injectors are original other than #2 and #8.
I have a F350 that has intermittent power loss.
View 14 RepliesIam looking at a 2000 7.3 Powerstroke that has some problems first it is hard to start cranks like it has a dead cyl. Second after starting it has no power not even enough to move. At first it would only run if held wide open but once it warmed up it would idle and rev and move but barely still had a miss. The weird thing is it did not smoke blue-black or white also no strong smell of diesel and no smell of oil at all. The truck has 230ish miles and there are no maintenance records.air filter was new.
View 7 RepliesOK . 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.
View 14 RepliesI have a 2000 7.3 I've been struggling to figure out why I do not have a lot of power below 2k rpm... The truck screws once it gets above 2k.
Assuming it was a turbo issue - I had the turbo rebuilt and put the wicked wheel in. Made a huge difference overall but truck still bogs under 2k.
No leaks in up pipes, they have been replaced recently. What the problem could be?
I have a 1999 7.3 with 260k miles. It is all stock with the exception of straight pipe. I got the truck about 8 months ago and have put about 5k miles on it. Have never had any issues with it. I was driving from Dallas to Houston and about 45 minutes into the trip my truck lost power. I was going about 65-70 mph and the service engine line came on and I lost power. It was running rough and was blowing white smoke. I let it sit for a couple minutes and started it back up and ran fine until 30 minutes later. It did this 2 more times on the way to Houston. Oil is good, coolant is good. Not over heating. Threw a code the first time but didn't throw it the other times. I brought it to a mechanic and he thinks it's the Wastegate.
View 14 Replies2000 F250, 7.3, 170K, running rough, knocking loudly, missing, shaking, no power to get up driveway, intermittent, no codes spit out at all. No smoke visible, no leaks visible, New fuel filter, air filter, update cam sensor, new fuel rail lift pump, new uvc harness, new glow plug relay.
View 14 RepliesI 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.
I need a wiring diagram for my 2000 F-350 power mirrors also to go along with the power window schematics that I posted before.
View 8 RepliesSo my 6.7 left me hanging the other day, went to start nothing. Towed it into town started. Went to start it couple days later nothing. Jump the plug by right battery starter turns. When key is turned to run no glow plug light, no fuel pump prime. Tested ignition switch good. Tried 2 new Batteries nothing. got power on fuse 52, continuity from fuse 52 to pcm connector. Fuse 49 and 50 also have power. Took all 3 connectors at pcm out and blowed air through and sprayed W.D nothing. Even tried with connector on transmission. Scan tool will not communicate with pcm.
Codes after cleared:
instrument cluster:
uo100 lost communication to pcm
u300a-64 ignition switch...
transmission:
u0294 lost communication with pcm
Body control module:
u0100-87 lost communication with pcm
B10f1-14 key in switch short to ground or open
Having issues with the instrument cluster and lost communication trouble codes. My truck has been having issues and it loses comm with all the modules. All the warming lights the truck has come up on the LED screen in the dash and if I turn it off it will not start. Most recently my traction control light stays on and my tranny is locked into 5th gear. I have park, reverse & 5th gear. Most recent DTC's are lost come with TCM & ABS control module. It seems to be getting more consistent but was very intermittent. Spent a week at ford with no progress. Truck wont start for a full day and then will start the next morning? When its bugging out it wont even prime the fuel system of turn over. Cab was off last fall to install SPE diesel STG 2 short block, Industrial compound turbo kit & water/meth kit. truck has been amazing and insane power until recent electrical/computer issues. When truck is bugging out tuner will not communicate with the truck and cannot read codes or remove programmer.
View 14 RepliesI'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?
View 14 RepliesThe 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.
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.
View 7 RepliesWhile headed back to town my 2000 f350 7.3 with 444,650 miles (I'm original owner) and have performed maintenance and repairs since mile 3. Truck started to loose power and eventually stalled, was able to restart several times to limp home 7 miles in one hell of a snow storm. Very confused, replaced cam position sensor ( keep one in jockey box ) replaced fuel filter truck starts then stalls out. Don't know if a bad HPOP would allow start up at all. Fuel pump???
View 6 RepliesI own a 2011 f350 diesel. So 2 weekends ago when it iced over in DFW I ended up doing a bunch of driving in 4wd. I pulled out a couple people, even pull out a semi.
After this the truck went on the fritz and gave me a CEL regarding the tcm losing communication with the rest of the electrical system. The truck was stuck in 6th gear and all things related to the tcm gear indicator didn't work. (remote start, backup camera, traction control, stability control and trans temp gauge). I did have drivability issues with the trans when it would sometimes bang gears when i would get on it suddenly and it could get generally confused at times, so generally I drove it pretty gently. The truck had to be towed to the dealer because after a while it would only get neutral of 1st gear and obviously it shouldnt be driven like that. They replaced the tcm under warranty.
The kicker is that all of that trans bs is now gone, there's no more confusion and gear banging.. drivability improved 10 fold. Obviously they updated the software but i was wondering if that was all that was needed to get this trans in gear? (pun intended) maybe they did something else?
I have a 2000 f350 manual transmission with electronic shift transfer case and my 4x4 won't kick on I've put it up on a lift and tried again but the front driveshaft won't spin and the light on my dash for the 4x4 won't work I'm also throwing 4 transfer case codes....
