Ok..for any doubters out there! My truck has been down since december because i figured the vp44 was shot. I came accross this video and thought I would do all he said except the grounds. I just didn't think it could be that. Everything else checked out so all I could try was the grounds. And after cleaning all the grounds, the damn thing started right up and I saved a couple grand. Thanks for the great advice!
I do a complete ground inspection/cleaning once a year. Just pick the nicest day in the spring or summer (no need to break a sweat), power wash your rig top, bottom & side and go over every ground you can find. Remove the ground if in doubt and clean/sand the connector and body to get down to bare metal. A little dielectric grease on the connection and you're good to go. Trying to locate an intermittent ground along the side of the road at night will drive you insane (been there).
This was after I replaced the returns behind the head and from the injector. Making sure the copper washers were good and the T connection was sealed properly. Make sure that line isn’t air locked
Any normal test light will check grounds, just put the clamp for the light on the positive battery terminal. Then touching any good ground with the light probe will light the light.
@@ChadMyers73correct, but the light puts a load on it. Light stays lit solid and consistent. A meter will show the voltage, but without any load. Pros & cons both really
Harbor freight sells a probe that checks positive ( red light ) and negative/ground ( green light ) . It works decent for checking wires and doesn't cost much
Very helpful info. I have a 2000 dodge cummins . 5.9 24 valve. 2 wheel. Its clucked out on me. Its will crank but no fluid going. Whlent to oriellys to use there scanner. And it said fuel injection pump valve. Open circuit
Ok I have a 1998 2nd generation dodge 24vavle diesel have to start it with starter fluid I just put new injectors it's got a lift pump and injector pump once started it start when idles at 1 rpm it sputters then dies
Great video I'm trying to diagnose my vp44. Truck won't start after it's hot until it cools and going down the road it struggles to get up to speed and that symptom comes an goes. I'd hate to buy a new pump if that's not even my issue. Everyone that knows this motor is saying it's the pump.
My truck was throwing a crank shaft sensor code. I change the sensor now it would start. I checked all my grounds. It has fuel pressure I’m at a complete lose. Do you have any idea on what it could be? The check engine light went off after changing the sensor but now it won’t start
My truck runs and drives but it goes in limp Modelike if I press a gas pedal aint doing nothing and then I got a code for the injector/VP 44 and timing. Don't know where to start. Besides buying a new VP 44 and don't really want to do that.
@@rosshoffman7377 No, mine has been getting the P0216 error code for about 5 years now. The truck still runs great. You can clear the code but it comes right back. I guess I'll just run it till the VP44 dies.
I've got a 01 3500 with 24v that keeps showing the p0216 code and mine runs great but I'm having issues with my throttle response. I've replaced the apps/tps 3 times and reset it a few times and now it keeps popping up with p0222 and a p0121 code . Both are tps sensor codes . Any advice would be great . Times like this makes me wish I could've found a 12v instead
I have a 2002 5.9l 24v and it has a p0216 code. Injector pump doesnt have 50 miles on it. It has stock lift pump in the tank that was replaced recently. Starts up with 15 psi of fuel pressure. Any ideas to fix it before the new vp44 goes bad again?
One thing I forgot to mention was the codes I had on my truck. This is the codes I had When turning the ignition and also with a scanner. PCM 0122 TPS sensor 1693 Companion code ECM 1693 Companion 0382 Glow Fault 0380 Glow Fault 0215 Fuel Injection Pump Circuit 1689 No Communication Between ECM and Injection Pump
11:34am 1/10/25. I have an issue with my 00 manual. It started I hit reverse went about 10 feet then the truck just shut off. Then no start at all. But weird part is I have zero codes. Any idea what this might be
This video is really going to help me out this weekend. When I was driving home today my truck completely died and cut off and now won't crank back up so I towed it back home. My lift pump is good so I'm guessing it's my vp44 because the truck cranks over fine just won't fire off.
My truck did the same. It was below 0 here in Colorado. Wont start. I replaced the Fass filters. Still won’t start. Hopefully it’s just air in the lines. Great video. 2001 2500 6speed 5.9L
@@eddiebartlett5972 I changed my filters and cracked my injector lines until fuel started coming out and then tighten them back up and the truck cranked back up and has been fine ever since!
My brother my brother, i hope you see this and respond, I'm working on one of these in a forklift and it originally had a mechanical lift pump, i ran an aftermarket electric pump from the tank... Is there any trouble that could cause?
my truck is acting like it ain’t getting full fuel. it starts, runs, and drives.. just doesn’t want to go when you start driving. i cracked the fuel pump and it squirts out fuel like it should. great pressure there. but i don’t wanna replace the injection pump without knowing thats it for sure. any ideas for me?
I have a 00 24 valve I keep loosing communication between ecm and injection pump is my ecm bad or my injection pump going out I'm getting 1689 1693 code
I’ve been having an issue with acceleration when my truck is cold. I hooked my scanner up and drove the truck and it says I’ve got about 11.4-11.8 volts at my vp44 depending on rpm. I’ve already replaced the pump but I guess I’ve got a wiring problem or ecm issue?
Maybe off topic a bit..... But i just bought a 2002 24v , and I've replaced the oil and later on noticed that i was overfull, and smell diesel.... Thought i had Leakey injectors, so pulled them out, took them to get them test and turned out to be ok, replaced the copper washers on them and installed them back, replaced oil and sti have that same problem...... Any help would be appreciated on tips to where to go from here
@@ChadMyers73 thank you for taking the time to help.... I thought of a cracked head or piston, but i have no blow by at all, the engine does not misfire or nothing, once it starts it runs flawlessly, could the vp pump be a possible cause???
Checked all grounds, sent ECU off to get checked twice, gauge cluster tests good. Anything else you can think of before I replace engine harness and relay board under hood? Thank you for replying.
I have a 1998.5 RAM 2500 5.9 24 valve Turbo Diesel that is throwing a code P0216 "Injection Pump Timing Failure" I received a quote from the mechanic for $6,350 to replace the VP44 pump and all fuel injectors. He says the fuel pressure is 10 pounds and should be 8 pounds and the excess pressure is resulting in the diesel fuel foaming up and not staying in a liquid form. Does this sound right? Many thanks for the information!
10 pounds sounds low to me . The 8 psi he mentioned is what the old ford 7.3 idi diesels require . I've got 14 psi on mine and I haven't done any upgrades to it however it does have a in tank lift pump but I'm not sure if it's a aftermarket brand like air dog or fass etc . I'm not too familiar with these cummins but based off my research you have to have atleast 5 psi at the very minimum or it'll damage the vp44 . I'm no expert so somebody correct me if I'm wrong always open to any help/advice knowledge I can get
Yes the safest way to do it would be with a breakout box. Otherwise you just take a ground and a power wire and hook it to the corresponding leads on the plug.
Buddy! I am having issues with my 2000 24v 5 speed. She starts every time and she idles great for the first 5 mins then she runs rough and rpms bounce between 800 to 1000. If i give a tad of throttle she jumps to 1050rpm and will not come down until i put it in gear. When driving it she seems ok until I start coming to a stop then she idles too high making it harder to slow down. Also when I rev it in idle to about 2k rpm it sounds like its hesitating/stumbling. Here is a video of that.. th-cam.com/video/_S2SmiQxg3M/w-d-xo.html Sound like a fuel issue to you? Any help is appreciated! Thanks so much! i wanted to check the fuel pressure but not sure how since my filter canister has been removed.
I do think it’s a fuel issue but it could be a multitude of things I would check for air leaks in your fuel system could be a bad injector could be a PCM issue with the VP 44. Check and see if there’s any codes stored and start checking for air leaks in your fuel system.
@@ChadMyers73 come to find out the new "Bosch" injectors I installed about a month ago are not real bosch lol. Had them pop tested and shop said they were between 220 and 250. So he said they were junk lol. Lesson learned not to buy injectors on Ebay haha.
if your not technical then all you hear is blah blah ^ _ ^ apologies.only next month change from winter to summer tires also mot a technical inspection and I demand fresh motor oil
You don't connect to any circuit when troubleshooting. Connecting it to any part of the engine will be a circuit. Direct to the battery to eliminate any false diagnosis... Bro. Are you working on people's shit?

Went through his whole check list. I finally pulled the return line above the fuel tank and it finally started to kick off.
This was after I replaced the returns behind the head and from the injector. Making sure the copper washers were good and the T connection was sealed properly. Make sure that line isn’t air locked

Check all your grounds and clean them. That’s what mine ended being.
Where and what kind of fuel pressure gauge have you got I can't find one mine is all over the gauge not accurate please help thank you

What if I have voltage on pin#5 all the time when key is on? What pin#8 does actually, what voltage should be present there?

Put your test light to positive an check your grounds

What is pen 5?
You should only have power to pin 5 for about 3 or seconds after you turn the truck off.
