What else besides a sticky plunger, would cause the fp reading to be all over the map. According to my gauge, I'm at 78/79psi at idle, but can see it dip to 70ish or spike to 90 while using our driving. My cv's are removed, fp reading is pre-filter and wiring seems good....
View 4 RepliesOk so the saga is continuing, not sure if its because enigma hates this mod or if I shorted something out when I was cutting the wires and mistakenly touched the ends together (protected terminal ends) some how or the monitor piece is just old and the fact that it has been my previous truck and this truck for a total combined 8+ years causing this conundrum....anyways the gauge seems to work (yay?) but it looks to read only "8"DC V?? but I know the power port (in dash) works as expected....so I am a bit lost here....one of the digits does look to be faded out as if the device perhaps is going bad and needs replacement....
View 11 Replies2000 7.3 EOT read 272* with engine cold new Ford sensor only getting 3.95 volts at sensor plug and at the 42 pin connector from PCM should be 5 volts, dropping 1 Volt some where I disconnected all the sensors that share this voltage IAT, EBV, ICP, IPR, MAP no change. I left the EOT unplugged and the truck runs good I'll run it like this.
View 14 RepliesJust bought this 1999 7.3 drove it a couple days now and got to walmart today. shut it off to go inside and came back out. turned on key waited for wait to start to go off. cranked the motor over but it didnt fire. i tried it again and nothing. oil is full, oil pressure is good while cranking. no rpm reading on gauge while cranking. no check engine light. batteries are literally brand new two weeks ago. Cam sensor?
View 4 RepliesI've had an ongoing issue with my fuel gauge reading incorrectly, and now I'm trying to fix it! Basically, it will change all over the place while I'm driving (not erratically, but definitely moves occasionally). I recently fixed my overhead display, but the "miles to empty" display doesn't seem to be very consistent. It will read 450 miles to empty, and then the next time I look at it, it will have dropped 100 miles or something (after minimal driving).
So I'm wondering where I need to begin looking to fix this problem. I've replaced the dash cluster using Circuit Board Medics, so I'm fairly confident that's not the issue. I've read that it can be the fuel pump or the fuel tank sender, but how to check if these are actually the problem or how much time it will take. Luckily, I've never run out of fuel and been stranded, but I need to fix this or it's only a matter of time!
I have an 02 f350 7.3 power stroke...Yesterday I noticed the outside temp was reading wrong,it was jumping from 67 to 86 to 92 back to 67..Temp was prob around 90 with high humidity and my a/c was on..So I got to where I was going and when I restarted my truck to go home the fuel gauge dropped to empty(I just fueled the day before) and fuel light came on and outside temp still wrong on the overhead digital display...Are these two things related???
Stopped the truck restarted it and fuel reads correctly again....Went out today and fuel light back on and on empty...Outside temp wrong again,a/c is on .....I disconnected the batteries when I got home to "reset the system"if there is such thing, fuel gauge working but outside temp wrong..?? Where is the outside temp sensor ?could condensation be running onto the sensor and throwing off my temp gauge? Just strange that both these things happened at the same time......I don't think its a fuse or they wouldn't work at all. I should mention all the other gauges work correctly...
Yesterday I noticed when I parked my truck the Speedo was reading 10 mph. I drove around a bit and used my GPS to get my real speed which was 10 under what the Speedo read. I parked the truck for the night and in the morning nothing had changed, I drove for a bit and all the sudden the Speedo worked like normal.
Later that say the Speedo got stuck at 50 mph and now when I stop it reads anywhere between 50 to 60 mph and goes up from there. When I'm doing 30 mph it'll read 80 to 90 mph. Cruising on the highway it reads well over 100 mph.
I've done some reading and it seems like it either the cluster or a speed sensor. My cluster has had a lot of problems lately of not working at all, no gauges work, radio turns off and the Windows don't work but a good slap on the dash will fix that most of the time.
I recently bought this Ford F250 6 with 117k... I've had it 3 weeks and it is now at 120k... My Odometer is reading Fast. From Tucson to Phoenix it read 302 mi, on my trip monitor it read 102 mi.. I've made this trip many times before and 102 miles is about right. It's a big issue because I get paid by the mile.
View 13 RepliesI tried searching here for a pid to get oil pressure. Can't find it. Is it possible to get oil pressure readings on these motors? I assumed it would be because we have a dummy oil pressure gauge on the dash. I thought it would be in the pop up list of gauges on Torque but I didn't see it.
View 6 RepliesI'm just curries as to the highest millage on a 6.7. I have a 2011 and only 36,000. My 7.3 had near 300,000 when I sold her and the engine was still running strong. Wondering if the 6.7 has that same longevity.
View 14 RepliesLast November I forgot to plug my truck in and it got down to 0, my girlfriend tried unsuccessfully to jump start it. When I got home I jumped it and got it running. I took it down to a heated shop to troubleshoot the glow plug circuit. I discovered it was not getting 12v to the glow plug relay. Also I started it and tried to back it up in the shop, when put in reverse it killed the engine, not lugged it down it was like you shut the switch off.
Also I discovered if you turn the lights on it kills the engine immediately. It will not crank with the lights on either. So far I have replaced the computer,ignition switch,batteries, and cam positioning sensor. Now comes the weird part!! I decided to get it running and pull the bulbs out of the back up lights I pulled the drivers bulb first then the passengers side bulb. When I pulled the passengers side bulb it killed the engine.
It is not my daily driver so it still sits in my shop. I have a hunch it's a ground issue but I've checked and cleaned up all the grounds I can find and it still has the problem.
I've had a scangauge on my truck for years and today while on vacation I noticed the voltage was fluctuating between 12.5-13.5 while driving. It has always ran at 13.5-13.7 .... I checked it with a fluke and it is a solid and steady 13.8v at idle. Why would that gauge be fluctuating like that? Truck seems to be running fine.
View 6 RepliesThe oil and water readings on my SG have been gradually climbing for the last few year to where they are about 15* above the ambient temperature after sitting over night. My question is could the values for the other readings be getting high. For instance going down the road at 65mph my ICP was 1250 and my IPR was 62.
View 3 RepliesJust changed the fuel filter in my '04 6.0, no issues worked just like normal, filter primed truck started, great. Well now my fuel pressure gauge is reading dead 0, I know that can't be right because the truck is running, but noticed my fuel mileage seems about 2 mpg lower all of a sudden. Had R&R Injectors installed about 40k ago, figure it's just a bad gauge but wanted to check and see before messing with the frickin wiring. Also, have had a lot of pressure buildup in the coolant tank, has had head gaskets and studs, anything else it could be besides head gaskets? Have had a lot of wiring issues with this truck from the previous owner....
View 14 RepliesI have a 2003 Excursion 6.0. I didn't post this in the 6.0 section because it may not be just a 6.0 issue. (See what I get) On cold starts, anything under 150 degree water temp reading on the SGII. I get a CHECK GAGE light on accompanied by the check engine light. No codes read on the SGII pending or stored. Just some of the time I get a water in fuel light too. This tends to go out fairly soon after driving. (Even after I just drain the fuel pump it still happens.) other issues that accompany the lights are as follows.
The trans temp does not give a reading to the dash. The oil temp does not give a reading the dash. Both show proper temp on the SGII. When in reverse the back up alarm beeps as if something is behind me. And the auto door locks will not activate after 10 mph. The tach also will not show a reading in the dash. SGII shows the numbers. Now the kicker, this ALL gets resolved the instant the water temp hits 150 degrees. The only lingering issue is the that the tach will surge or drop every now and then. The tow/haul light does not come on when this is going on. I've checked the battery terminals all are clean. Both batteries are brand new.
I am still failing to appropriately diagnose the problem(s) with my '03 Ford E-350 7.3L Powerstroke. This van has only 69,000 miles on it. A week or two back (just a few days back in work time) it suddenly went from running perfectly smooth, clean and wonderful to this:
- Zero power. Putting the van in gear and flooring the engine causes lots more smoke not nearly any rev of the engine and just a crawl forward.
- Lots of smoke out the back exhaust, whitish. I cannot discern wether it smells like diesel or oil (because I'm ignorant here), but the smell is very strong.
- After warming up and idling ~ 15 min I check under the coolant cap and see no signs of bubbling or disruption (from opening the cap in the coolant tank).
- After warming up there are no warning lights visible on the dash, and I don't have a computer to read codes (if there are any to read).
- I replaced the turbo up-pipes which had a visible leak previously. This did not hurt the symptoms, though no more visual leaks under the dog house.
- I thought maybe I put gasoline instead of diesel in the truck, not so.
- To do the above test I had to use the fuel pump to get gas out the tank to test. I hijacked the fuel pump output and turned the car on a few times to get gas out to a tank. The pump seemed to work just fine.
This was all very sudden which is perplexing, and, in use, the van was previously an ambulette and in my few miles with it (maybe 200-300 only) use was extremely light for such an engine/van, just driving around doing errands. I am not sure if this is relevant (no one has suggested so, yet) but before all this happened I uninstalled the rear HVAC that came with the van when I bought it. The AC lines were sealed under the hood. The coolant line was returned at the doghouse (you can see this at the beginning of the video).
At the moment the van has no power to go anywhere. I have not yet checked the CPS or IPC sensors, and understand this might be the next route in standard troubleshooting?
2003 Ford E 350 7.3L Trouble - YouTube....
I have a 2002 7.3L Screw 4x4. Will a 03/04 6.0L instrument cluster work in this truck? The 2 clusters appear identical. I put the 6.0 cluster in and the trans temp, and coolant temp gauge will not work. All the gauges sweep when it is powered on, but the coolant and trans temp lay flat, and the check gauge light is on. All other gauges and functions work. When I put my other cluster in, all gauges work fine. Is there a difference in the VSM, PCM, or the SCP communication?
View 6 RepliesI 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.
View 3 RepliesI 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 RepliesI 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.
I just finished a cab swap and I'm having a little trouble. Here's a link to what I've done : [URL] ....
KOEO the WTS light, battery light, SES light all stay on and no power to fuel pump. No communication with PCM (using AE). All fuses are good, but no power to PCM fuse (#22). When I apply 12v to #22, the truck will start and idle - but poorly because I still don't think fuel pump comes on. The idiot lights all stay the same.
I did get to pull codes while it was running and got stuff like IAT circuit high (its not plugged in), fuel pump relay short to batttery, and a few other short to battery things (park assist stuff IIRC). I thought that might have something to do with the redneck idea to boost the fuse with an external power source?
Just thinking while typing, I don't have 3rd brake light hooked up yet (just thought of that, I'll hook it up first) and bed/bumper are not installed, so no tail lights or park assist stuff is hooked up. I'm also not using overhead computer, so it's not plugged in.
My next step is to go back through all of the connectors and make sure something isn't 1/2 way plugged in or possibly plugged into the wrong place(s).
Looking thru the wiring diagrams is not a strong subject for me, but I was trying to figure out how power gets to the fuse and how PCM relay works (does it complete circuit to ground to energize the coil?).
