- เผยแพร่เมื่อ 21 เม.ย. 2021
- My 1996 Dodge Ram with the 12 valve Cummins started losing power on the highway and when I glanced over at the fuel pressure gauge it was at 0 PSI. Quick video documenting my findings. `

I like this because it’s the kind of common problem regular people deal with. No in depth computer analysis required
Yeah man got to love the old mechanically injected Cummins! Caveman repair
Needs zero electronics to run. EMP proof
@@NoNonsenseKnowHow that's why I have one
Same problem happened to me with my airdog. Truck would hardly start and hardly had 10 psi of pressure. Changed the filters, I had 27-28 all the time. Fuel filters are always first thing you should check
Hey man I like your videos , you don't do that whole long intro BS and subscribe groveling before getting to why we are here. Keep it real!
we have had that problem in the uk producers putting more bio diesel in petro diesel coupled with the anti waxing additives then the cold weather and boom a filter full of snot .
Thanks for that.im having the same problem,no high rpms ,no boost ,no power, and put new turbo tv cable ,and new tps. We'll see 🛠
i got a question about my truck i’m getting a tps below voltage the p0122 code and i changed the tps and everything and i cleaned the wires and stuff but still getting it
12 valve Cummins best motor ever
"It was all off-road on a farm" 😉 just in case the EPA is watching, right Chris? 😂
you could always add a filter head and another filter under the truck... size matters when it comes to fuel filters on these.
Mine did that it was the injection pump called dead peddle it’s a known problem
Regular diesel won't do that, unless you get a bad tank from a shady station. I change my filter every 12,000 miles as per cummins recommendation, and it always looks brand new.
Had a similar problem but I had to change the pump too
Sounds like you need a Tork tek ofv010 overflow valve and possibly a new lift pump and fuel filter
I did all those things to my truck cause it was intermittently ticking. And also started running inconsistently changed all of it and it runs like a completely different truck.
I always just floor to it after a fresh filter change
Is it supposed to hold pressure when the engine shuts off?
ive run about 500 liters of used oil from work through my 12v without issue so far, its all stock and i havent changed the filter since doing so, i put about 40 liters of diesel into the tank when i think its getting low and then top off with used oil, it was mostly hydraulic oil out of boom lifts as work has a rule that all fluids on all equipment need to be changed every year.. im not complaining when i get 150l of basically new hydraulic oil out of every change, its mixxed with the engine oil aswell and a little bit of gear oil from the final drives, but the vast majority is used hydraulic oil
You run mixed oils through the fuel system?
@@derajyellat102 yeppp, whatever was rained out of machines at the shop went into the tote, there was a second drum there that i poured in anything nasty, if oil had metal water or nastyness in it id put it in there but engine oil, hydraulic oil, little bit of gear oil all mixxed together, used diesel too 1.50 a liter for diesel in canada right now thats almost 6$ a gallon... doesnt take much of the stuff to pay for any parts it MAY wear out faster
goes through two filters before it enters the truck and then another on the truck, not to mention i let it settle in 1000l totes and have the pickup 6" high so it doesnt suck water or gunk off the bottom
@@AndrewBrowner dude that's wild, I knew that they could run on almost anything. I'm looking into installing a tank, filters, and valve controller to run vegetable oil
@@derajyellat102 its nothing new people been doing it for a long time, doesnt really make sence when fuel i 60cents a liter but at 1.50$ theres no arguement its certainly worth the time and money.. looking at about 500$ minimum cost to get setup with a fuel pump, tank, hose and nozel, filter housing and filters ect and you can spend as much as you want on a setup with multiple settling tanks and centrifuges and dozen step filtering higher flowing higher quality pumps, fuel heating filtering and pumping on the truck can all be improved
i just went the cheap route 1000l tote 50$, princess auto filter housing, napa 2micron fuel filter, a marine fuel filter/water seperator, tried a 70$ amazon pump it died got another and it died, so put the money up for a 200$ fillrite pump, one of their cheaper ones but should hopefully be built better then the chinese junk i was getting
no aftermarket lift pump?
Its usually that damn prefilter/heater. Mine wouldnt start because diesel was actually coming out of the electrical connection. Definitely delete it unless you want problems.
Bugs live in diesel. Theres dieselcide to treat your tank to kill the bugs. Change filter afterwards. They look exactly like whats in your filter media
Mine too... turns out that little bit of time with low fuel pressure killed my injection pump. Then the replacement Injection pump was bad. Fun times
Oh damn I just recently about 7 months has to rebuild mine , it was my first experience $$
Diesels are picky. CLEAN fuel only. Change filter often. Don't leave new filter laying on the bench.
I’m sure your a 12 valve guy but did u do the ticky tacky of the dowl pin
Yeah. Made sure to do that first thing when I got the truck. The pin was still in there
@@uslt5028 im in the same boat with similar mileage, idk if mine was done or not and i dont really wanna tare it down to find out knowing that at some point ill probably be in there anyway to change the timing, crank pulley or something along those lines.. i kind of feel like if it didnt fall out over the first 25 years and 600k km's why would it fall out at all
although my trucks stock and i could imagine adding fuel and boost could add more stress to the timing cover as the pump is working harder, the extra force could maybe work the dowel loose but i doubt it, seems it either had the issue or didnt
Wow, I bet you don't run heating oil through that truck again!
Has nothing to do with heating oil all i ever ran in my old dually was heating oil / offroad fuel never had that happen at all but have seen tht before diesel fuel filter will get like that if not changed in sufficient time or if they sit alot
Never mine I saw the end of your video
I have seen it with regular diesel also
Cool, good to know. I'll definitely be changing the fuel filter before 20K this time around
yeah 20k miles is probably around 4 cubes of fuel depending on how heavy the foot is, or how often it sees in town miles and towing.. think about 4 cubes of fuel going through a softball sized filter it doesnt take much grime to end up filling that filter, especially when you add any contamination that gets in during fueling, or possibly grows in the tank, i know ive certainly knocked a few pieces of dirt into my filler neck while fueling
PS it’s usually a weak fuel pump that causes the injector pump to go out.
Yeah I'm hoping I didn't do any damage by driving around with that clogged fuel filter. I drive the truck pretty easy so probably not.
That's mostly a 24 valve problem with the vp44. P pumps can take some abuse.
@@BrianFromZion2012 yeah if you get this issue with a vp44 pull over and fix it right there or get it towed, the drive home can be enough to wreck those IP's without proper pressure.. with the p7100s if theres enough fuel to run its happy send it cross country
Heating oil didn't cause that.
you have a alge problem, add some bioclean at your next refuel. :)
No it was informative get lazy and let stuff slide and you'll get stranded
Just sell me the truck .... Go buy your self a Prius
Bro my truck runs 1500 rpm doing 55-60 2k rpms I'm doing 70-75. Yours is lagging hard.
Lagging? Sounds like just different gearing to me
