Does the yellow injector solenoid cap change color with mileage and age?
I have a guy that has a set of injectors out of a truck that got scrapped. He's estimating mileage at 40k based on the fact that they caps are still yellow claiming that caps start to discolor around 60k and they get darker with miles/age.
im in the process of replacing the injector cups and i knew this would happen since the whole process went way to easy up until this part. I am using Clays remover kit and it will not remove the cup. I do it according to the book and it just keeps popping out of the cup when i try to remove
View 14 RepliesNow ive got a tick tick tick tick sound from the engine. The tick increases and decreases with rpm and is present at idle. If it were a gasser i would say a lifter, honestly it kinda reminds me of a sewing machine lol.
Whatever it is as long as its not serious and my engine is solid im ok w it, I bought this truck knowing I was going to have to put work into it, I just didn't know work was going to go fall one after the other week by week from the day I got it....the previous owner must really have neglected this thing....
Hard to hear it over the sound of the engine, but its there, and is slowly getting worse

Although not certain, I *thought* I saw coolant run into the front drivers side injector hole when the injector was out and I leaned on the radiator hose. I had knowledge t pull them and changing the orings who were initially concerned then not concerned after looking closer.
Either I made a mistake in what I thought I saw on my first experience with injectors, or there really is a problem that I didn't know enough about to address at the time. So I opened this thread to get more info and stop hijacking 67speeda's thread, found here: [URL] ....
As per recommendations, I will check my coolant bottle for any fuel, oil, residue, etc. I am also going to reach out to my buddies and see if they saw a problem with coolant, too, or they realized it wasn't coolant and I didn't take note of it ...
It was a REALLY LONG day and my ability to concentrate had begun to slip quickly (health issues), so it's possible I missed something there. So IF I saw coolant going into that cylinder with the injector removed, how bad would that be? I thought it came from pretty high up and ran down where the injector sits..
So after hitting a pothole, it would seem like half the engine lost power, after some searching around, i found that i would most likely be the harness inside the valve cover that has lost connection.
Its the right side, so i would need to take of the turbo pipe, and probably something else to get to it.
Since i'm doing this job, what to check out along the way? I want my 7.3 to be as reliable as possible.
I will probably ask some questions along the way, it can be a challenge sometimes to own a car that not many mechanics are familiar with, but as i have read online, this should be a very straight forward fix.
Can the harness be upgraded so it doesn't happen again? Its an 02
Story 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.
Would it be a good idea to change the injector hold down bolts when I do the injector o-rings? They have never been out at 333,000 miles.
Plan on doing glow plugs, injector wiring, valve cover gasket's, intercooler pipes and the dreaded oil cooler.
I have an 01 F-250 Powerstroke. It has been shaking terribly at around 1500 rpms and shutters while holding the brake and increasing engine speed. I took it to the dealer and they told me that my #1 injector is bad. I decided to check around a little bit. I found a diesel service dealer that has brand new injectors. (Not rebuilts). Anyway I would like to attempt to install this injector myself.
1. Which injector is #1? (I've done a lot of mechanic work but not a whole lot on engines.)
2. What do you do with the fuel and oil that get into the cylinder? Do you have to get it sucked out?
3. Anything else that is crucial? What do you have to torque the injector bolt to?
I just bought a 99 F350 with 240k miles on it and got it for a deal because it needed injectors. Ive done the same job to my 97 OBS powerstroke. The injectors were already pulled so I had them sent for rebuild, the problem is I cant tell which injector goes where. is there a trick to figuring out where each injector goes when I put it back together?
View 4 RepliesRebuilding my 7.3 and I'm in need of the removal and install tool for the injector sleeves/cups for the 7.3 Powerstroke Diesel.
I'll pay all shipping charges and a small fee if required. I hate purchasing a tool I'll never need again, rather better not need.
I have a 2002 F350 7.3L w/superchips programmer, k+n cold air intake. Does NOT smoke a lot from tailpipe
Not running rough since I changed my oil to rotella 5w-40w synthetic.
Appears to have good amount of blow by coming from the oil fill when engine is warm.
Can Bad Injector O Ring(s) cause blow by and oil consumption?
I have an '01 F-350 7.3 Turbo diesel. When the engine is cold it chatters quite a bit and after it warms up it still chatters a lot but not as bad. It starts right up every time, even on cold days. Doesn't have a miss and idles smoothly (except for the noise). Seems to run fine with plenty of power, just really noisy. It has an edge programmer on it with 5 settings- Stock, Mileage, Tow, Race, and Extreme. When it is set to stock, mileage or tow, it is pretty noisy but about the same on all 3 settings. When it is set to race or extreme, it sounds like the engine is about to fly apart but has really good power. I never run it in race or extreme because it sounds like it may be hurting the engine.
View 14 Replies1999 e350 has 130k and original injectors, had a minor power loss while driving that i determined was injector o ring needing replacement since the fuel bowl also had black colored fuel. installed and have been cranking for about 4 days now and am recharging batteries again. whenever i changed any injectors in the past I've refilled both sides of the oil rails although on this one I didn't. So wondering what to expect concerning the process of filling oil rails via hpop. Does have a hpx line...

I just replaced my injector cups a month or so ago and also injectors with some lower mile injectors. but now 3 weeks later still not getting any pressure at icp. I have dead headed pump got 3k plus but when i block off ether head i get no pressure. i have pulled injectors and checked for orings and they are fine...
View 2 RepliesI bought this truck a few months ago. After trying everything under the sun to try and rectify a poor running problem, it was realized that injectors needed replacing. Ended up putting in 160cc/30% unlimited diesel performance injectors. The truck has a rough idle and surging problem. After trying to install the chip from gearhead, the truck didn't run any different, ultimately (according to the shop doing the install) smoking the ECU. New stock ECU, same problem. Goes good under throttle, just idle is bad. I get weird looks at the gas station. People think it has a big cam.
7.3 Rough Idle - YouTube...
I'm trying to find a part number for the wiring harness that sits on top of the motor and plugs into the valve cover gaskets. The previous owner replaced the pigtails but the wires were cut so far back that there is virtually nothing left coming out of the harness. What the actual harness looks like other than it has the 9 pin plug on it or whether both sides require an individual harness. What is the part number or picture of said harness. Just in case.... it's a 2001 7.3.
View 14 RepliesI have been reading here about alternate methods to torquing the hold down bolts for the injectors. This winter I replaced my old stock split shots with new alliant single shots. I installed the injectors into a cold engine and torqued the hold down bolts to 10 ft lbs. I did not ever go back and re-tighten.
Is it suggested to go in and re-tighten the injector hold down bolts to 10 ft-lbs after the engine has been heated up and cooled down? What are some symptoms of a loose injector? I am imagining premature wear on the injector cups, low compression and maybe some mixing of oil into the combustion chamber.
Did just throw the injectors in and go back later to retorque only to find they were all fine or were some loose?
Well, I've been getting a flashing OD light, so doing some research, led me to replace the shift solenoid. I did just that and have yet again the same P0741 code... The truck seems to shift normal but will randomly throw the code and then will not go into Overdrive as well as shift very hard into all gear. Where to look next?
View 1 RepliesI replaced the rings on all 8 injectors put in 8 new glow plugs and a relay. My truck is still putting out grey/ white smoke at start up. It goes away after about a minutes. Truck runs a little rough a first then smooths out. I know some smoke after doing a job like this is to be expected but I was thinking I t would go away by now. I've been running through my head what I might of done wrong but I can't think of anything.
Does it just need all new injectors and not just rings ?
2001 f250 7.3
I have a 2000 Ford F550 7.3. I bought a Superchips programmer to read the codes on my truck and up pops this P1316, so I did some research and found out that the most common problem is the injector wiring harness. I bought new valve cover gaskets and the injector wiring as well because the truck is old and I figured new wires wouldn't hurt.
So after installing the new wiring harness and gaskets I'm still getting this Code! The truck idles rough and serge's sometimes, also there is a lack of power and some shaking between 40 and 50 miles per hour, however form 50 to 60 MPH seem's to be just fine. I don't trust the "Mechanic Shops" around here and will only take the truck in as a last resort.
