Ford 7.3L Power Stroke (1999-2003) :: 252k Not Giving High Ohm Readings - Replace?
Sep 16, 2016
Replace them? Have a new set on the shelf, however, the 252k ones that are installed now give no high ohm readings.

View 7 RepliesMy Volt gauge on the dash has started reading around 10V with the key on waiting on the GP's. Batteries read +/- 12.6V with a DVM in a static state, no key.
But, quickly as best as I could see the reading on the DS battery drop to around 10V with the key on, GP's cycling. Cranking drops down around 8Vish.
After starting the reading on the DS battery is back up to 10V. This lasts anywhere from 30 seconds to a few min. Then it jumps up to the expected 14.6V reading.
I cleaned up the battery terminals and clamps while doing my turbo,and all the connections are tight.
I have replaced hpop, lpop gears and cover, stand pipes, dummy plugs, rebuilt high pressure rails, and i still have issues. The icp readings on torque pro are mostly below 100 hot. I am clueless... I ordered the icp air fitting but it wont be here until tuesday.
View 9 RepliesSo, I'm replacing the Steering Box today and read an article that said you should replace the pump at the same time. what do you all think?? I have clear access to it now and they are not all that expensive?? Or are the ford one's bullet proof and leave it alone???
I don't have any leaks and it feels ok I guess..just pushing close to 200K on it.
So I tried to replace my thermostat and housing and the housing bolt snapped off. Ok so I tried to extract that bolt off and the extractor bolt snapped off inside. I am guessing it might just be easiest to replace the water pump now? I am pretty much at the end of my mechanical rope which is short anyhow.
View 6 RepliesI have a 2004 Solara. Ever since I could remember, the outside thermometer has been giving me false readings. When I pulled out of my garage today, the outside thermometer read 50 degrees. I drove to work without stopping for 60 miles and the gauge still read 50 degrees. When I got to work, the gauge quickly dropped to 41 degrees.
This problem has happened many time before. When the car is in motion, the temperature will not change. When the car comes to a stop, then it will adjust. Where is the sensor for the thermometer? Maybe the air is not reaching it due to the high speed.
My high pressure power steering hose just blew at the "B" nut at the pump. Meaning, the fitting is still in the pump but the line is out. Do I need to replace the whole line or is there a retainer I can swap out?
View 14 RepliesI just replaced my 3rd HP power steering line last night( 3rd in 300K, always blows the same point....fitting comes apart where it attaches to the pump.
I'll start, mine have gone about 100K plus or minus 10K, almost thinking about making it a 100K maintenance item.
Pulled our 5th Wheel up to a campsite we like in the Eastern Sierra, have pulled this trailer there several times before. This trip it felt way down on power and the EGT's were getting up there, I saw 1320 and it would have gone higher if I hadn't backed out of it. It had good boost 24psi averaged 17 to 20 on the steep long pulls. We came home today without the trailer and it ran just fine except once when I really nailed it the emission system light came on and stayed on solid till I turned the key off and on. What is the Emission System light telling me? It ran just fine when the light was on and all indications on the Scangage were good as well a on the Boost, Egt and fuel pressure gauge.
View 14 RepliesI just had a remote start installed with a turbo timer that works off of the parking brake being engaged. No matter how hard I press it the light does not go on, however when the installer probed the sensor to ground it, it worked fine.What part this is that needs to be replaced. The stealership quoted me at 200 something for a whole parking brake assembly.
View 14 RepliesStory starts when I was cruising down the freeway and the truck cut out, seemed like a CPS or Injector related issue - seemed like a whole cylinder bank cut out. Stopped truck on shoulder, she shuttered and died. Turned truck off and restarted, ran like a top for about 4 miles then did the same again. I restarted it again and drive it straight home, ran like it I usually did.
As soon as I arrived home I did a little research and learned to start with CPS. I replaced my grey CPS with a new, Ford grey CPS. Truck fired up, ran the same that it did before - not the best idle but at 302k I was content. Drove it for a few days and it did it again, hobbled the truck home, although it did do it a few times and the last time it did it was really hard to start.
I replaced the IDM through NAPA. She's a work truck so I wasn't going to splurge for a Swamp Unit, the NAPA one came with an 18-Month Warrenty. She started right up afterward, the smoothest idle I had ever felt and she ran great, except for an SES. I ran the code and it was an IDM code, ran a buzz test and it pulled injector #5 high/low error, but it buzzed (a bit quieter than the others).
Here's the weirdest part, when the motor is cold the SES is constant, but as it warms up it only shows under power and sometimes flashes off at certain RPMs (1700-1900 and 2100-2300) and turns off when engine braking (TC locked) returns at idle. NO engine lights with the old IDM. I've checked the wiring to the injector from the 42-pin to the outer connector. (.6-.7 ohms, what my meter reads without any loads) Injector (from outer connector) reads 3.2 ohms. UVCH is less then 2 months old (GP issues) injectors have less than 5k on them.
Why? New injector solenoid? Bad IDM? Is it possible my last one never fired #5 and it got stuck? Or did my old IDM fry #5? Also I'm going to keep driving it and maybe it'll clear up, there was one drive I took where it cleared up completely. I've done some extensive research on this an i'm stumped. With the new IDM the truck has run better then it ever has.
My new to me 99 f350 has a great a/c but it only blows on high. Am I looking at a blower motor, resistor, or the fan switch? I'm grateful that it does blow on high being in SE TX and SW LA. If it didn't I couldn't ride in the old girl. A black truck with no a/c is not happening this time of year....
View 12 RepliesI notice my trans temp gets really hot fast. For instance just moving my trailer from front of my house to side yard makes temp go to 250. Without any load and driving a couple miles it does the same thing. It's been doing it since I installed the trans temp gauge just trying to figure out what's up.
View 14 RepliesI have a 99 f350 and I can't get my truck to kick up the idle when it's cold out. There have been mornings in the negatives and still nothing. I replaced my egr tube and cleaned the exhaust pressure sensor. My exhaust back pressure valve opens and shuts while driving at slow speeds but not while at idle, but I don't know if that's related. I replaced the oil temp sensor with a ford motorcraft one. And I plugged my intake air temperature sensor into a buddy's truck with the same motor and his truck still idled up no problem.
View 14 RepliesI had a p1211 code when I first got Torque Pro hooked up. I figured it was just because I'd done a couple WOT runs and the HPOP just can't quite keep up with the injectors. I was told this might happen when I ordered the injectors from Gear head. I also noticed that my ICP peaked at around 3600 during one of these runs. I don't have it logged, but I'm certain it was up that high.
The code hasn't returned, but I haven't been running it too hard either. I don't quite know what to make of the ICPs actually being that high. From looking at a bunch of Rich's graphs his doesn't really get past 2800 or 2900. Is this an incorrect reading? Do I need to worry about anything?
What kind of engine oil temps are too high? I know pulling the other day it got as high as 220 but I honestly only have the gauge cause I got it for free. Whats happening at the different temps? I know for trans fluid but not for engine oil..
View 10 RepliesTowing 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.

The "Check Hybrid System" message came up on my dashboard. I took it to the dealer, and they said the temperature sensor on the transaxle was giving erratic readings. Unfortunately, they said that the only way to fix it is to replace the entire transaxle. They said I could keep driving it and that it would probably go into disabled mode before it caused any more damage. What I should do? It's a rebuilt 2012 Prius with 25k miles.
View 19 RepliesI don't know if its a coincidence but it rained hard all weekend and went to work this morning to find out the blower motor only on 4(high). I checked the plug going into blower motor and it looks dry and clean. is there a common occurrence with this? What to look for?
View 14 RepliesParts came from Riffraft Diesel Performance. A set of "o" rings for the injectors. High flow CVD fittings for the fuel lines. Turbo rebuild kit. (its got 210,000+ miles) Anti Surge compressor wheel.(ok its not part of the oil problem)
Photos to come. I will take during the rebuild.
