Old 6.5-T strikes again !

[M123KT-450]

No sir i did a very fine job of building my wire harness as the truck has ran great all winter long. when this repair was done i had little to no money as i was in the off season so i had no income so yes i relocated the PMD/FSD from the intake to the bumper and all them issues went away.

I do not keep such tools at my house as i do not repair Vehicles here.

I also figure you so called 6.5 experts could have simply said what was bad and what need to be done to fix it.
But it seems to me you have no idea whats going on and are simply just plain guessing. . .well if i wanted to do trial and error i would just start replacing parts till ran. . .

I have a friend who is going to run to the shop after work and get my multimeter and test all of the things you say to test with then.
Then the fuel/Vac gauge will be gotten as well. . .I hope if i had another set of wheels here i could have done all of this myself. . .

What i find comical is none of these Issues surfaced until you guy talked me into putting 2 stroke oil in my fuel now 3 tanks later i have a ton of issues from a truck that had been running just fine. . .

I blew a valve in my head the day BEFORE i was going to install a Turbo master in my truck. Had I installed that TM first, I would have thought it was the TM that caused the head failure.

2-stroke oil just makes up the for the lubricity difference of ultra-low sulfer vs the diesel that was available when the truck was designed.

as long as you kept a very low mix such as 128:1 that wouldn't effect it. If you through a gallon in there, or waste oil to save money, then i can see that making a problem.



I know you aren't insinuating that the people here that are taking time out of their day to help you, aren't the ones you are now blaming for your 6.5-T running poorly??

 

[M123KT-450]

I ain't blaming anybody for anything i was just simply saying what i was doing before it started acting.
I was leaving it up to you 6.5 guys to say yea that could be it or no that is not it.
I'm just tossing out ideas as you were.

Just me getting told my wiring harness might have been a shotty throw
together where you implying:

i do bad work ?
or
simply stating a bad wire harness will cause issues ?

it could be taken either way so there for i see no difference in yours and my comments. . .

Reread post #1, sounds like you got a bad tank of fuel or it was the accumulation of crap over time that got sucked up when you ran the tank low. Can happen to a gasser or a diesel. I wouldn't blame the 2 stroke oil.

 

[M123KT-450]

that is what i was assuming but the bucking coughing studdering missing not sure how say it got continually worse. as tho what ever it the problem is, its progressive as the act up's got more violent lasted longer and left the trucl running worse each time till it won't really run at all.

List and describe any other factors which are not addressed in this checklist. We can’t see, hear, smell, or touch your truck, so the more descriptive information you can give, the more likely it is that somebody can assist you.

Mikey try this

 

[buddy]

Ahhh, the checklist reveals some more pertinent info. its good at that.

starts then dies. Can you describe that?

Do you need any info on checking the codes? Like said before parts guy was wrong. It will save the codes in most instances, unless the issue resolves itself in a matter of a second while running then PCM may not set a code, and all you need is a paperclip. Codes will set even in a no-start just from cranking.

A PMD running all winter and finally giving up when it gets warm out sounds about right. Maybe the transistor nuts were loose. Although, getting codes will help. Most of the things recommended have only been diagnostic steps, except for a new PMD no one has recommended throwing parts at it. And the PMD is very suspect if it ever caused the stalling before.

 

[M123KT-450]

Have you ever had a carbbed gasser flooded ?
you smash it to the floor and spin the hell out of it. . . then it fires glugs alot then slowly reves up well just like that minus the reving up part. . .

I'll try to get a video be right back. . .


Mikey

 

[buddy]

Pics from Jifaire in your original PMD problem thread. It was suggested that you could make sure these nuts were still tight. And it was also said that the PMD would likely fail in a few months. If the truck starts then dies, you might get some more life out of the PMD if the nuts are loose and you tighten them. Again, its just another free test though.

 

[M123KT-450]

those nuts were tight last time, I think it's just wishful thinking guys. some thing is bad and needs to be replaced PMD or IP maybe even both. . .
either way both parts are out my price range at this time so neither are getting replaced !
If its the IP then it will never be replaced as its $1,999.95 after core exchange. before exchange its $3,499.95. i'll just replace the motor get a parts truck or replace thw whole truck before i spend that much. . .

Mikey

 

[NVW]

I posted earlier Pensacola Diesel has IP's with PMD for $650 and w/o PMD for $450. Thats a far cry from $1999.95
No Core Charge

Leo

 

[buddy]

Unfortunately PMDs suck and everyone on this site has probably bought one or two new ones at a much higher price that they are now, $163 at same pensacola diesel.

I can understand that even $450 for an IP is a big chunk of money, but I would only swap the PMD first, especially since its cheaper separate.

 

[M123KT-450]

the codes flashing are 19,29,35. What do these mean?

DTC 19 - Crankshaft Position Reference Error

DTC 29 - Glow Plug Relay Fault

DTC 35 - Injection Pulse Width Error (Time Short)

Mikey

 

[buddy]

29 could just be that the GP fuse was removed or its blown.

The PMD sets the injection pulse width, but the DTC is often thrown by some bad fuel, some cloudy stuff like when youre at the bottom and stirring up stuff. So it could be a number of things.

If you unplugged the CPS and cranked once it would set 19. If you have never unplugged the CPS then that could be an issue, and you should try unplugging it and cranking. Mine will work without the CPS, but only if I crank for like 10-12 seconds.

Should clear codes, crank again and see what comes back.

 

[JiFaire]

Pretty cool how you had codes even though the parts guy said you didn't, huh?

And if your glow plugs aren't working, that's another issue. Hmm. Didn't you already have that problem and try to cheapie your way out of it? I remember something about used glow plugs...

 

[buddy]

35 is iffy, usually only a cloudy or bubbly fuel issue, but the PMD controls the injection pulse width. The PCM takes the actual pulse width as seen and reported by the PMD and compares it to what the PCM thought it should be based on a number of things, such as commanded fuel rate and IP timing. The Optical Sensor provides a timing reference so when it can't see through the fuel correctly could be an issue. Usually 2-cycle oil will help stabilize fuel or lubricate a fuel solenoid that could be sticking in the IP.

Seafoam makes diesel conditioner too. So that code is tricky to dicipher. Could be a PMD issue or could be an OS issue or just some bad fuel.

No i did not use them used GP's the truck was already equipped with a set of brand new Hot starts just only one side of the motor was plugged in. . .

[M123KT-450]

Bad fuel and i was low on fuel it popped the WIF light it started bucking and stumbling limpped it to the fuel station threw a half tank aka 7 gallons of fuel then i dumped in half a boittle of the Diesel kleen red bottle 911. . .which was a way over done amount truck bucked and poppped for a good long while then i changed out the fuel filter and lift pump as instrucked to by DTR guys. . .then i filled it up. . yet instead of the trouble fading away it only got worse. . .

You said earlier that it cranked, but wouldn't fire. Then in another thread, you mentioned that it sounded like a choked gasser that was trying to start...

If it is trying to fire, glow plugs could be the issue. And what the heck are 'Hot Starts'?

However, if you are getting fuel to the IP, and no fuel from the injector line, it's PMD or IP or dual failed sensors.

Diagnosing an electronic diesel requires precise information... if you guess at things, or leave things out, you get a bad diagnosis. Not checking for codes didn't help; relocating the problematic PMD with a DIY harness adds more imprecision - by the way, you DID leave it on the heat sink, right?

Maybe you should just sell it to somebody and buy a gasser, Mikey. A diesel, especially an electronic one, might be too complex for you... maybe an older all-mechanical one would work better.
