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.
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.
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....
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
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.
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
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...
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
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
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.
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.
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.
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.
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
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
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.
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
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
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
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.
well... I would certainly watch the videos, if I thought you would be the one to repair the rot, putting in something that was missing and leaving that truck in a cheap and functional restoration for extreme work.... For me, it's no fun being done using professionals.
@@TruckMaster It's more interesting to see you trying and error and as it's a work truck it only has to look minimally presentable... but of course only you know how much time you have available... :-)

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

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 😂👍

Don’t tempt me on the flatbed idea 😂👍
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 😂
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
Hello! Im glad you finally got an exhaust to put on this rig
Please keep building this truck!

Great info
I would find a different one then this one to put major work into 😂
😂😂😂😂😂😂 I've seen bone stock 6.5s break the cranks and completely wipe out the block in the process.

@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.
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.
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

That’s so discouraging
I saw on the dash the fuel gauge moving weird. There could be a ground issue or fuel pump is failing.
I think a powdered oil fill tube would tie everything in really nice
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
Rebuild the engine with marine parts it might help the knocking or blow by
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.
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.
You plan on getting the windshield wiper arms either color matched or matched to the suspension in blue?
Not a bad idea
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
Thats a fancy Highway department truck!
Love them years on Chevy
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
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
The pmd will do that on them you all way have to have a spare one in the truck
Love your channel, so sad my LBZ was stolen and wrecked this week :( only had it for a year 😢
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
Take the silencer ring out of the front of the turbo 👌
I’d love a new turbski for my LB7 😃
Mine ran the same exact way. Injection pump was shot
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.
Send the pump and injectors to Area Diesel Service
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
100 percent the pmd same thing happened to my 94 6.5. Hard chop touch the gas and it would go crazy.
Illusion was the winner 🏆 gonna look sweet
I'd find a good PMD first. Then consider a IP.
Do a rebuild series on the Chevy
Replace this injection pump would love to see that girl get some performance parts lots of 6.5s still on the road
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
elec vac pumps are cheap,its the control sensor that tends to be expensive
Does it have the egr deleted?
Build the truck 🙏🏼 I love 6.5 trucks have several 😎
Seems like you need a new PMD
sounds like a bad pmd to me if that don't fix it then just throw a DB2 on it if its the pump.
Can you tell me the best scan tool for the Lly duramax
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.
Winter beater!!!!!!!!!!
Oh yes
Would you have a turbo to fit and idi 6.9 international
Please paint that e bike the same as the Sunkist truck.😅
Get a super 60 turbo
Go see the ole lady and let the bowties sleep lol meanwhile ya need to find out how much your buddy wants to buy Hammer's 6.0 Ford back ASAP 😂
Took my turbo off when I did this
How much can you get me a new c3 pump my 6.6 duramax is tuned
Bad pmd 10000000% relocated or not
Thanks
Fixer up
Great 👍
ahh yes the ole turboner
That's a 6.6 your going to have more than just a problems.
Oh yeah
that sounds like bad injectors
You lost me at 7” bro
Big haters out there 😂
6.5 loves injection pumps my 97 model eat 5 of them went to a power stroke till the duramax came out
If you blow it drop a 12v in it make it a sleeper pull truck
I like your thinking
well... I would certainly watch the videos, if I thought you would be the one to repair the rot, putting in something that was missing and leaving that truck in a cheap and functional restoration for extreme work.... For me, it's no fun being done using professionals.
