Hey brother is there anyway I could bring you my 02 LB7 I run as a hotshot truck, I’m having a few intermittent problems that I can’t get figured out. I can pay and you would be more than welcome to use it for content. Let me know something please and thank you sir.
I would take a look at your pmd before you throw an injection pump at it. Even relocated, the pmd's will fail. It just takes a little longer than the ones mounted on the pump. Usually, the part that fails internally on the pumps themselves is the optical sensor, which controls the timing
@TruckMaster also, if it has a PMD relocation kit, it could be the relocation harness. The cheaper PMD harnesses have horrible connections and pins in the connectors. I've also seen issues with the engine harness cause weird issues too. Most cheap PMDs use the original electronics which weren't the best. The Flight Systems PMD has a lifetime warranty and uses better electronics. Also Quadstar Tuning LLC is a good place to shop for the 6.2/6.5 diesels. They have all sorts of stuff both for maintenance and for upgrades/updates.
The wastegate issue could be a bad vacuum pump, vacuum lines have leaks, or the wastegate solenoid on the passenger side valve cover is bad. The 94+ 6.5 had issues with the vacuum system for the wastegate.
Get it up to temp. Load a new fuel filter with atf. Start it back up, rev it way up and shut it down. Let it sit. Hopefully this will clean up the injectors and pump.
Dude please keep making 6.5 videos!!! So underrated and there is barely any content on them!! We love it keep it up please! I’m build my 94 currently also look at Quadstar Tuning for 6.5 aftermarket parts and Leroy diesel
Doesn't matter what and first Gen or 7.3 owner says, the Detroit has the best idle sound ever put in a pickup, can't beat the mechanical sound of those motors.
Truckmaster, it's great to have you back ! Always enjoy watching your show. The old crusty rusty plow truck is a project for sure. But comparatively, you don't have that much into it. Once up and running, you can break even easily. Chop a bunch of that rust off... maybe a flatbed... some 40s... a 4 link front and rear.. coilovers... mud truck... off road rig... truck pull... ummmm. Well, I am sure you will figure something out.... good warm snow plow, lol... which will be handy soon....
look for a plugin jumper harness between the inj pump and the loom,it supposed to stop 60Hz interference,but the inductor that supply power to the pump breaks,also the earths on the inlet manifold dont work,solder them all to 2 thick wires and attech one to the block and one to battery negitive
Check for air in fuel. This could cause the surging and white smoke. Check your harmonic balancer, It sounded like it was clunking. They are known to go bad, will take out crank if not fixed. Also check PMD, always have a spare. It too can cause surging idle, among other issues.
i used to do alot of these in perth western australia,you need a tech2 gm scannner at a minimum,alot of people forget to put a resistor in the new PMD,they need to me mounted on an aluminium heatsink about 300mm long,stanadyne put out multiple recall notices on these pumps,they need an intercooler and upping the boost
I would check the resister that goes to the top of the injection pump. Those resisters cause all kinds of weird problrns.. next the module will do what its doing.. make sure its a stanadyne module.. their is a updated gray one.. also replace the resister that goes in the plug of the module. You removed the vacuum pump. It will throw a over blast service code and will defuel.. the fixx. Put a 2 or 3 bar map sensor on it.. that will make it think it has less boost. Last if the injection pump is going bad the guy you want to use is badger diesel in wisconsin.. he is the best. Yes I was trained by gm to work on the 6 2 and 6.5s.. if you feel like doing a little more to the truck you can convert it back to a db2 pump from a 6.2.. have badger rebuild it and turn it up.. makes a huge difference.. if you want to chip the oe electronic db4 pump either leroy diesel or heath diesel can make you one.
another issue is with the inj pumps is the factory test bench tests the optical sensor last when the pump is warm,the most common failure of this part is when the pump is cold,which puts the engine into limp home mode,oh and also NONE of the factory lift pumps produce the 14psi inj pump inlet pressure,a holley blue is perfect
Hey Man, I have a box of parts from my 96 6.5 turbo diesel suburban. I started replacing parts when I had a crazy knock. Turned out to be a balancer pulley with destroyed rubber in front of the harmonic balancer. Anyway, I have the injectors, a turbo, an injection pump, gaskets, PMD and probly more. All used of course except for a new balancer pulley that goes in front of the balancer. You are welcome to them as I sold the truck. Im in Omaha NE if you pass through this way sometime.
Also love the 6.5 content myself. Have a hx40wii turbo on the 6.5 in my 82 k5 and with headstuds have hit 20 psi of boost a couple of times with 17-18 psi being hit most days.
100% the injection pump if you haven't tried a new pmd. These are good trucks and i honestly would love to see you do a mild build with it. With a set of promaxx heads, stud kit, hx35(obtained) and a tune these things are pretty stout for around 280ish hp and mid 550lbs ish of torque. And get really good gas mileage doing so too. They definitely dont make dmax power but definitely are not terrible
😂😂😂😂😂😂 I've seen bone stock 6.5s break the cranks and completely wipe out the block in the process. You ain't getting no 550ibs out of them for very long it's like a 1000+ hp iron block LS with stock internals will they do it short answer is yes. Long answer is yes but it's a matter of when not if they'll blow up.
it is your injector pump. i have a 94 k1500 and it did the same thing and it was the injector pump. when you change out the pump you need to have a program to set the timing.
Check th fuel injection lift pump that’s mounted on the frame. That’s common besides the PMD that fails. It’s on the driver’s side framerail just below the driver door. It looks like an old fuel filter with 2 wires coming out of it.
I love my China Choo Choo! Bolted a $150 dollar Gt45 to my LS camaro over 6 years ago. Since then i've broke and replaced just about everything on that car but the Turd-ski. lol
Those 6.5 are ok driving around town but do not load them. Everyone i owned either threw rods or the crank broke. Had 5 it took a bit for me to learn. Stud the mains it helps alittle. If you turn up the boost. Get ready for carnage
I think it’s worth it to be honest I think they are decent ole engines for what they were intended to do they weren’t much a pulling engine or anything more of a fuel economy engine which they got great mpg 🤷♂️I always kinda liked em lol
My daily driver is a 1995 2500 suburban with a 2000 6.5 ... scat crank, holset hx40 turbo, head studs, main bearing studs and girdle with a 5 position tune...It tows a 10000lb. travel trailer and I push up 20psi of boost... It's not a duramax but it pulls hard... I will never part with it...
Neither of my03. Or my 04, 3rd gen rams leak a drop of anything on the driveway, but I have worked to seal everything with top end gaskets and etc to make sure they don't leak anything😅😊❤ it took a bit but it'd nice to not have them dripping anything at all😅❤
Hx 35s will go to 48 50 psi if ya really want to. Light years outside of there efficiency range at that point but they’ll go up there. And they whistle so bloody loud it almost goes silent up that high 😂
I still think the vacuum actuator controller thing that the waste gate line runs into is your issue. It’s not reading boost properly and just over fueling like crazy or holding the waste gate fully open. They have a weird way of controlling the waste gate on those things. Or a pmd or optical eye in the pump issue. Not a turbo
one thing i found with pmd they make two different plugs , i put the wrong pmd plug on mine and it kept popping out ! the very worst thing detroit diesel did was let chevy add junk electronics to these ! i had a really nice one with 120k i gave away after putting 3 different pumps in and not a one working right
We are doing that like that could it be the glow plugs that are just bad I would say it’s curious of a combination of both. I’m just curious because I’m buying one and I just keep trying to learn.
I would definitely start with a new pmd I have owned a couple 6.5s with the pmds relocated and I’ve had a couple pmds still fail definitely start there
Pmd can cause alot of issue and possible a stuck injector But i got a air in fuel inssue on mine and going to change the turbo sometime because that casues the headgaste problem on them and the lift pump also is junk when they came out and vaccum pump to And other emissions that on it And the way they did the oil pump wiring to if the senor goes bad it wont send power to lift pump Some people wire it to the key and stuff that what the person before me did but i put another 7 psi one because stock tubro
Question, with the L5P I’m looking into the RDS 64mm turbo 10 blade. How is it with towing? I two 5 days week 40hours sometimes more and what to know your thoughts on if it would be a good upgrade or not for towing
Get the truck hot shut it off remove fuel filter fill it with atf run it for 30 to 60 seconds till it gets to the injection pump and shut it down let it sit a day or so.
Can someone help me diagnose loosing fuel pressure on a LBZ duramax, it’s odd because it will start up run fine and I’ll drive an hour and shut it off for 10 min then it lost pressure and I have to prime it again.
Not to mention aftermarket rebuilt injection pumps aren't guaranteed to be great. If factory is good stick with that. Pmd do all types of funky stuff. The grey stanadyne one would be your best option

Honestly enjoying this old truck fix up, brings back a lot of memories of my old 6.5 suburban plow truck.

Good to know thanks
I have had the harness to the relocated pmd go bad which caused it to run ruff and stall and then not start

Rebuild the motor to see or for a good video which I'm not saying your videos are bad but I just want to see a engine rebuild
That 6.5 is great content which you can’t place a value on that. I’d love to see you restore it be pretty cool.
Thanks for the encouragement I hate doing videos on this thing 😂
Me too, not too many videos on these, somethung unique
Get it up to temp. Load a new fuel filter with atf. Start it back up, rev it way up and shut it down. Let it sit. Hopefully this will clean up the injectors and pump.

Don’t tempt me on the flatbed idea 😂👍

Please keep building this truck!

Thanks for the update, I honestly the enjoy putting turbos on old junk vids even more than the nice truck content lol
That’s good to know maybe I should start doing that more often 😂👍

Hello! Im glad you finally got an exhaust to put on this rig
I love this truck really hope you keep fixing it up.

Could be the pump but just because the PMD is relocated doesn’t mean it’s still good I still would try another
Thanks

Wow that's awesome, thank you! I probably will just buy a new one thanks for the offer though
I think you should swap out the PMD with a known good one if she wants to take off on you. Had that issue with mine.
Also love the 6.5 content myself. Have a hx40wii turbo on the 6.5 in my 82 k5 and with headstuds have hit 20 psi of boost a couple of times with 17-18 psi being hit most days.

Great info
I would find a different one then this one to put major work into 😂

@Big-lron that's lack of maintenance to the harmonic balancer and main pulley, you can get forged cranks for these motors
@@waaa141995 still it's a week design that the motor grenades because of a harmonic balancer.
that badge goes in the honey comb part of grill on the orange truck. proper already figured that out!
it is your injector pump. i have a 94 k1500 and it did the same thing and it was the injector pump. when you change out the pump you need to have a program to set the timing.
They sent you that plate cause it was the off cut from the big plate. It was a bonus so it didn’t go to waste.
Check th fuel injection lift pump that’s mounted on the frame. That’s common besides the PMD that fails. It’s on the driver’s side framerail just below the driver door. It looks like an old fuel filter with 2 wires coming out of it.
Thanks I just replaced that and it didn’t fix the problem
I would completely restore that chevy diesel in a heartbeat, always wanted to own one
I haven't watched your channel in a while but i definitely want to see you restore the green truck n the blue n orange almost looks like gator colors.
Thats a fancy Highway department truck!
I love my China Choo Choo! Bolted a $150 dollar Gt45 to my LS camaro over 6 years ago. Since then i've broke and replaced just about everything on that car but the Turd-ski. lol
Those 6.5 are ok driving around town but do not load them. Everyone i owned either threw rods or the crank broke. Had 5 it took a bit for me to learn. Stud the mains it helps alittle. If you turn up the boost. Get ready for carnage
You must have never replaced the harmonic balancer with a fluidamper.
@lio.motofab no i didnt. But i replaced the stock ones several times because they spun on the bonded rubber sleeve.
@ same thing happens with the main pulley
Good video keep the video coming on the 6.5 👍👍
I will watch all the 6.5 videos, so you will have money to make videos on it! Thx for another great video.
Should do a build series on it. Frame off resto, another wild colour, make some power with it. Why not right? It’s only money
I think it’s worth it to be honest I think they are decent ole engines for what they were intended to do they weren’t much a pulling engine or anything more of a fuel economy engine which they got great mpg 🤷♂️I always kinda liked em lol
Look it up but you can use kanola oil in smoke machines instead of whatever chemical you use now😊
I think a powdered oil fill tube would tie everything in really nice
My daily driver is a 1995 2500 suburban with a 2000 6.5 ... scat crank, holset hx40 turbo, head studs, main bearing studs and girdle with a 5 position tune...It tows a 10000lb. travel trailer and I push up 20psi of boost... It's not a duramax but it pulls hard... I will never part with it...
I saw on the dash the fuel gauge moving weird. There could be a ground issue or fuel pump is failing.
Neither of my03. Or my 04, 3rd gen rams leak a drop of anything on the driveway, but I have worked to seal everything with top end gaskets and etc to make sure they don't leak anything😅😊❤ it took a bit but it'd nice to not have them dripping anything at all😅❤
Hx 35s will go to 48 50 psi if ya really want to. Light years outside of there efficiency range at that point but they’ll go up there. And they whistle so bloody loud it almost goes silent up that high 😂
Nice 👍
Rebuild the engine with marine parts it might help the knocking or blow by
6.5's are notorious for having pmd failure even once relocated. Everyone I've talked to that has owned one always kept an extra.
You plan on getting the windshield wiper arms either color matched or matched to the suspension in blue?
Not a bad idea
I still think the vacuum actuator controller thing that the waste gate line runs into is your issue. It’s not reading boost properly and just over fueling like crazy or holding the waste gate fully open. They have a weird way of controlling the waste gate on those things. Or a pmd or optical eye in the pump issue. Not a turbo
I love the Fl. Gators colors 😅😅😅😅, I enjoy your videos from central Fl. By the way, Your truck would bring BIG $$$$ down here!
I’ve definitely considered a Florida buyer
I’d love a new turbski for my LB7 😃
one thing i found with pmd they make two different plugs , i put the wrong pmd plug on mine and it kept popping out ! the very worst thing detroit diesel did was let chevy add junk electronics to these ! i had a really nice one with 120k i gave away after putting 3 different pumps in and not a one working right
That’s so discouraging
Love your channel, so sad my LBZ was stolen and wrecked this week :( only had it for a year 😢
The pmd will do that on them you all way have to have a spare one in the truck
Love them years on Chevy
That orange looks good with the blue
Take the silencer ring out of the front of the turbo 👌
100 percent the pmd same thing happened to my 94 6.5. Hard chop touch the gas and it would go crazy.
keep it and fix i enjoy watching it, i used to have one
Leroy diesel would be a good resource for the 6.5 diesels
Hey dude, it would be sweet to see you rebuild the engine and make it a sleeper!
Those are really bad for injection pumps an glow plug going out. But other than that you can’t kill them trucks like the 7.3 power smoke
elec vac pumps are cheap,its the control sensor that tends to be expensive
Hey Truck master!! Question. Best parts shop for stock fuel injector replacements with the standard upgrades in them for LBS Duramax?
Now I know where too get the hsp stuff for my new LML
We love the 6.5 content
Send the pump and injectors to Area Diesel Service
Mine ran the same exact way. Injection pump was shot
Do a rebuild series on the Chevy
Build the truck 🙏🏼 I love 6.5 trucks have several 😎
Illusion was the winner 🏆 gonna look sweet
Yeah don't blow that truck up it's nice to see it being fixed up I have a duramax but still have a soft spot for those old diesel trucks
Replace this injection pump would love to see that girl get some performance parts lots of 6.5s still on the road
I'd find a good PMD first. Then consider a IP.
We are doing that like that could it be the glow plugs that are just bad I would say it’s curious of a combination of both. I’m just curious because I’m buying one and I just keep trying to learn.
I would definitely start with a new pmd I have owned a couple 6.5s with the pmds relocated and I’ve had a couple pmds still fail definitely start there
I would also check to make sure your lift pump is running underneath the truck.
I think you should buy a GMC 2500 with a 6.0L and then install a turbo for towing without DEF.
Pmd can cause alot of issue and possible a stuck injector
But i got a air in fuel inssue on mine and going to change the turbo sometime because that casues the headgaste problem on them and the lift pump also is junk when they came out and vaccum pump to
And other emissions that on it
And the way they did the oil pump wiring to if the senor goes bad it wont send power to lift pump
Some people wire it to the key and stuff that what the person before me did but i put another 7 psi one because stock tubro
Question, with the L5P I’m looking into the RDS 64mm turbo 10 blade. How is it with towing? I two 5 days week 40hours sometimes more and what to know your thoughts on if it would be a good upgrade or not for towing
What year 6.5 had a Bosch fuel pump or ecm recall ?
judging by how it shakes....watch the return line for air and i suspect your injectors want to be freshened up.
Seems like you need a new PMD
Get the truck hot shut it off remove fuel filter fill it with atf run it for 30 to 60 seconds till it gets to the injection pump and shut it down let it sit a day or so.
Can you tell me the best scan tool for the Lly duramax
I had one and the pmd was moved and it did the samething I replaced the pmd and that’s all it was
I’m definitely trying that
Would you have a turbo to fit and idi 6.9 international
Hey I saw the raffle but I can’t enter or view more of it
sounds like a bad pmd to me if that don't fix it then just throw a DB2 on it if its the pump.
Does it have the egr deleted?
Build the truck!
You think so? She’s pretty beat up
@TruckMaster yes! Maybe not the best financial sense for youtube views but man there is something special about these year trucks with the 6.5
@TruckMaster i would highly recommend finding another truck with a 6.5L detroit. I wouldn't put a ton of money into this one.
would like the link for the turbo
Make it immaculate before they increase in value
Can someone help me diagnose loosing fuel pressure on a LBZ duramax, it’s odd because it will start up run fine and I’ll drive an hour and shut it off for 10 min then it lost pressure and I have to prime it again.
Seriously just plug a new pmd in! They always crap out. Even relocated
Thanks I will try that
Not to mention aftermarket rebuilt injection pumps aren't guaranteed to be great. If factory is good stick with that. Pmd do all types of funky stuff. The grey stanadyne one would be your best option
Please paint that e bike the same as the Sunkist truck.😅
Man I would love to but this truck off of you
Keep doing some 6.5 content
put a semi truck turbo on it and see if it will spool
Get a super 60 turbo
Call the truck wire brush. Because it needs all of them.
Great 👍
How much can you get me a new c3 pump my 6.6 duramax is tuned
It sounds like one or more of the injectors isn’t firing
I have that turbo on my 24v cummins and it does just fine. Builds boost quick and is reliable surprisingly I've been using it for about 8 months now.
