No more air in fuel leaks on 6.5L Turbo Diesel
Просмотров 7 тыс.8 лет назад
Used O'Reilly's part # 7-081522 clear fuel line at the return line on the injection pump to test and see if there are any more air leaks. Have spent many months repairing fuel issues on my 1999 Chevy Suburban.

First trip out after upgrades to test it out. New fuel filter. New lift pump. New fuel sending unit. New relocated Dtech pmd. Sealed fuel lines.
PMD Relocation 6.5L Diesel

PMD Relocation on a 1999 Chevy 6.5L Diesel Suburban. Dorman 904-104 PMD Kit. I left the old PMD to rot where it's at. Impossible to remove without taking the intake manifold off. If I said anything incorrect, be patient with me. I am not an expert. Just know enough to make it work. ;)
Make Diesel Great Again. Make America Great Again.
I would have liked to see a video that actually SHOWS the PMD relocation from start to finish. Not just talking about it after the fact. I just went through the process, and it is a bitch. Even after removing the upper rad hose and a wire obstructing the PMD connector, the connector is barely even visible and it took me about 1 hour of constructing a wire coat hanger with properly shaped hook and figuring out where the connector clip is and how to unclip it, and then actually hooking it and unsticking it, and then hooking it again and fishing it out. Unsticking is the hardest part and that is why a coat hanger is necessary and not just some baling wire which I tried first because the wire must be really stiff/strong. Even still I had to pry the wire as close to the connector as I could get with a large screwdriver before it finally popped loose. This whole PMD thing is amongst the stupidest ever designs on a diesel engine. I spit on the GM engineers that came up with this. "Hey guys, let's really mess with em and put a thing that fails regularly and shuts down the engine immediately in a totally inaccessible location, hahahahaha".
I watched at least a dozen videos on pmd relocation and yours was the only one that actually explained where and how to get at the original harness. Thanks Man!!! Excellent video
Thanks dude. Glad it helped you. (I don't have access to this channel anymore, but I'm the guy who made the video)
👏
Why do you sound like you just ran 3 miles then shot this video
Southerners talk slow. Just making sure everyone understood what I was doing there.
I just want to thank you for explaining and giving someone of a visualization of how to take off the wiring harness. I watch at least 15 different videos of people changing out this PMD and making a video and none of them explain how to do. This is the one I should have watched but got to go through all of them I guess to find the right one so just wanted to say thank you good job.
Thanks for letting me know, my man. (I don't have access to this channel anymore, but I'm the guy who made the video)
Wow
Makes me miss my 2000 crew cab 6.5
Useless Video!!!!
lol, I never thought it would get over 20k views. I only posted it as a novelty to show that my tank refurb went well.
Useless comment!!!
I bought a dorman pmd and it lasted 4 days. Has a lifetime warranty. Got a new one, added a relocation kit, i then relocated it to the front bumper. Lasted about 3 weeks then left me stranded 1hr away from home. Any idea to why they are failling so fast?
Yes, dormans are trash. Use a D-tech.
very cool! It is interesting to know the real fuel consumption of such a car. and how much is this, if not secret
17 mpg
I had the same truck: 99 Suburban diesel. The last year of the diesel for the Suburban. I miss that truck a lot. It was my first SUV, and it was totally a “go big or go home” deal. I wish they still offered a diesel for that truck- it’s the perfect engine for a large heavy SUV. Incredible torque, longevity, and fuel economy. The engine design was damned near ancient by 1999, but it still worked well. All I needed to do was remote mount the PMD and replace the oil cooler lines, and it was a reliable beast. I bought it with 143k, and sold it with 210k, still running great. Only breakdown I ever had was a belt tensioner pulley broke, which was a Chinese aftermarket one anyway put on by the previous owner.
It warms my hear to read this after being quoted $50 for a Chinese "GM" pulley, only to find a Dayco US made one at the next place for $37.
What do you think can causes these to blow black smoke out of the tailpipe and not be able to go past 15mph?
This is diesel and it's very quiet!
Trang Doan they get loud when they start to run like dog mess. Leak in the exhaust noise, just one example but Goode truck if you stay ahead of them and give iTLC
Do you still have the truck?
Yea, will always have it. Original owner.
Ever thought about selling?
Nah, I'm the original owner. (My other youtube account). I like it too much to get rid of it.
He needs fuel go to the gas station and get some diesel it's not good to run them that close to empty.
This was immediately after having dropped the tank and replacing the sending unit and lift pump. Read the video description. The tank was immaculate and had no crud in it. Having only a couple of gallons in the tank was intentional for the test drive in case there had been some reason to have to drop the tank again.
Crud isn't the issue. That's what the strainer is for. It's your first line of defense for foreign objects. He's probably referring to the cooling aspect i.e. in tank pumps are cooled by being submerged in fuel helping longevity. Running them on low level constantly will shorten their life although i get it for a test run.
@@jcallum8408 - Except that 6.5L diesels don't have a fuel pump in the tank. There is a lift pump mounted on the frame in between the tank in back and engine in front. This lift pump then pressurizes fuel for the injector pump under the hood. Also, the GMC/Chevy 6.5L diesels from the 1990's are self-priming due to that lift pump and could also easily be "air purged" at the fuel filter (also in the engine bay) if any air gets into the fuel line. Cheers!
@@mattp5991 if the truck goes on a slope, would starve fuel causing the injectors to fail?
Just another stupid car myth
Thanks I just scored a 98 crew cab Cheyenne
Hi everyone, how do I disconect the cable from the old PMD? What kind of technic I should use?
You have to use a flathead screwdriver to pry the clip up
How's the reliability on the late model suburban diesels?
After you take care of the fuel system issues and relocate your pmd to the bumper, they're just fine. Good mileage for a 7k lb vehicle. I get around 17mpg.
Grate but this 1 is gas, I have a Diesel Ford f250 and it's grate on fuel
@@neoblackwolf69 redline at 4k. No, it's a diesel.
We renewed everything on the truck, including the timing set, water pump, suspension, steering, steering pump, alternator, complete AC system, complete cooling system, belts, hoses, brakes and master cylinder, all the sensors under the hood, new clock spring, injection pump, turbo charger, replaced the leather on the 2 front seats, complete new Pioneer speakers and amp, Sony stereo with everything, new door looks, handles, all lights are LED including dash, grill, headlight/turn signal front and rear fixtures, new mirrors, and probably forgot a few extras...only the main chassis, rear axle, motor (new at 100k), and transmission are original. I plan to keep this baby until at least 2040...and she runs and looks like new. BTW, with excellent Hankook tires the entire change over cost me (including a Chinese Tech 2 GM Computer) $8600. Bought everything new at Rock Auto or EBay. Best investment I ever had! Only paid $4500 for it in 2011 @195,000 Mi. I believe I own a vehicle worth at least $80,000 IF you could ever find it!
@@neoblackwolf69 Nah, it's a 6.5 turbo diesel. It runs quiet. I'm the original owner since 99 and have taken good care of it.
can you please tell me why did you have to change the pmd. I have 1999 ck3500 6.5 diesel the throttle is not responding it just surge's back forth by itself from 800 rmp to 2500 rmp the truck generates alot of smoke.. im just trying to figure out what my trucks issue. thanks
Julian Salazar I replaced my original standadyne pmd because my engine would just shut off while driving. Common problem with stanadynes. My first replacement was a chinese dorman. Cheap junk and it caused my engine to surge up and down uncontrollably. Finally I replaced it with a d-tech and it has been fine for over a year now.
Julian Salazar My original stanadyne would cause the burb to stall out. Other brands can cause the surging you have.
99 sub with factory 6.5TD? Nice. What were some of the issues you found? Post a video of the whole burban
Yep, it was a custom order. Back in Dec 2015, the original pmd failed. What I didn't know then, but have discovered is that pmd's generally fail to heat problems, but not just from heat soak in the engine bay. It's fuel irregularities that cause the pmd to go bonkers compensating and correcting fuel flow. I bought a dorman pmd and it failed after just a hundred miles. I had a ton of fishbiting which indicated air in the fuel. So I tested the lift pump and it had failed. Replaced it. Dropped the fuel tank and found a rusty fuel sender. Replaced that. I then also sealed and painted my fuel lines. They were not rusty and didn't need replacing so I want to keep them that way. This fuel return line test was the final check to make sure I got it all fixed.

NOTICE - The Dorman 904-104 PMD I installed failed after just 100 miles of use. It went to wide open throttle, very dangerous. There are three types of PMD, Stanadyne, Flight Systems, and Dorman. Dormans are chinese ripoffs of Flight Systems. Stay away from that garbage.
Can't even see my pmd I have a 93 Chevy 6.5 I can't find my pmd how can I find it
@@wilsonvalentin17381993 6.5 Turbo Diesels have mechanical pumps. So there is no pmd issue to deal with. That started in 1994.
The original PMD Harness is short and that is about as much as your going to get it up and out of that location. When replacing the PMD, always ensure you also install a resistor on the new PMD before you connect it to the harness....
96, you are correct. Like many who have changed a PMD for the first time, I initially forgot to put a resistor on. An engine will run but fuel is restricted. The fishbiting effect above 50mph gives it away along with sluggish response and lack of power. Easy to fix by remembering the resistor.
@Dakota Duree Resistors come in values from 1-9 you can pick them up at most auto parts stores. Look on the Leroy diesel website and he has how to videos to show you how to install the resistor onto the PMD Pins
