2nd Generation Dodge 24 Valve Powertrain

So 2 days ago, I disconnected my grid heaters after testing ac noise. Which was .034 after using them all winter. Now the wait to start comes on like normal, I turn truck over it's barely stars and then dies.so I turn it over again, get it to idle, and its puffying out white and blue smoke like a train from exhaust. Temperature was 36 at 7am when I started it. I disconnected grid heaters at battery like it was suggested so as to not throw codes. I feel like I should just reconnect the grids back up, i haven't replaced a alternator yet since i have had the truck for 6years. When i use them truck fires up first crank with just a haze of blue …

Hello all! I have developed a hard start/ long crank after the truck sits for awhile, even if just over night. I thought the bat's where bad so I had them checked and they were good. They guy at the local shop that does just starters and alternators has a 2nd gen. Cummins and thought it cranked a little slow so I put in a rebuilt starter.( I took it apart when I got home just to see and they did put in oversized contacts like the ones from Larry B's ). WOW! It cranks almost twice as fast now. Thought I solved my problem but the next morning it still cranked for 3-5 seconds til it started. Used to be it would roll over 1 time and light off and it is still that way when it…

Hi All, have not been on the site for a while. To many other things in life going on. Had to go reset my password to get back on. So I have a quick question for you all. In the last week my truck 1998.5 24V has been acting up. After it sits overnight, go out in the morning to cold start it, it will fire right up, run for 10-15 seconds and then die, like it ran out of fuel. Then it is a real bear to restart. It acts like it's out of fuel, or losing prime. It only does this the 1st cold start of the day, the rest of the time you shut it off and restart it throughout the day, it fires right off and runs great!! My driveway is level or flat, no steep inclines ar…

Over the last few months my trucks has randomly had a long crank to start issue. Only has happen maybe 4 times. It usually takes less then a second and shes running. But when this long crank happens it usually takes between 3 and 4 seconds to start. This always happens after the tuck has been sitting for at least over night. Also the last few days I have noticed a light gray colored smoke coming from my stacks when I step on it. My truck is completely stock as far as turbo injectors or chips go and I have never before made smoke (which is how I want it ti stay haha) But the last few days it seems to smoke more. Are these two issues related? What should I be lookin…

Buddy of mine has 1999 dodge truck, 5 speed 4x4. He replaced the vp44 & installed new injectors, the vp44 had failed, had that 16xx code, can't recall the exact code. The truck is hard starting, if it starts at all, if it does it idle's smooth but blows thick amounts of white smoke (i'm assuming lots of unburned diesel fuel) and the pedal is dead. White smoke does not go away.Several things I thought of vp44 installed wrong (timing key), injectors and/or connectors torqued wrong, over flow valve ???? I'm grasping at straws here, any suggestions appreciated.Thanks in advance.

2001 6 speed. So here's the story. Lately when the truck sits over night it cranks 10 seconds if not more to start. Rest of the day is no issue. I've got 20psi to the vp44. I've parked nose down. I've checked every bolt and fuel line. I've checked and load tested the batteries. Batteries are a touch on the weak side but not bad. I cannot for the life of me figure it out. Fuel tubes and injectors were pulled and re o ringed ect. A year ago. Any ideas? I'm honestly down to replacing the vp44 check valve and the fuel heater on the canister o rings. I understand its losing prime somehow but I'm having a hell of a time finding where. Once it fires up its bump the key and it po…

I’ve searched quite a bit for info on this subject. But it always seems to pertain to trucks with after market lift pumps. My truck still has the stock lift pump. Are these hard starts still a VP issue? Truck runs just fine. For now I’ve installed a toggle switch off the ground wire of the stock pump. As long as the pump isn’t running starts right up I’ve yet to install a fuel pressure gauge which I know is a must. Was also looking for suggestions on a good one and wear to hook it up

Hey folks, I've got a hard start issue that started when I pulled off the interstate in 115 degree heat. Almost always has a hard start if the engine is warmed up and sits a couple minutes now. Sometimes it will hard start if sitting overnight. The first time was 1k miles after a fuel filter change on a road trip from Vegas to southern Idaho, but I did the standard bump the pump and it ran great after that. I can't see any fuel leaking anywhere. I've always seen a little drip off the tank if I really top it off, but that's been the case since I bought it. I just ordered a DDRP from FASS, but haven't installed it. I'm driving a loop from Vegas>Oreg…

Started having an issue a couple days ago. Had to crank the engine over way longer than normal. Drove to work and shut the truck off and it started right back up. Tried about 15 minutes later and the hard start issue returned. The angle the truck is parked doesn't seem to have any effect on the issue. Have tried completely removing the edge comp and it was no help. Checked for any codes, none stored. Checked over the fuel system and didn't have any leaks. Has bluish white smoke when it does finally start. Seems to start easier and faster if I give it a little throttle while cranking. Runs great after getting it started. --- Update to the previous post... Thought…

my hard start is kindof spiratic. Im worried I have a cracked diaphragm in my vp44 is there any way to tell? But, it also wont start hard down hill. I cant find an air leak in my return fuel line. Anyone have any ideas or suggestions.

just happened all of a sudden started out taking 2-3 more cranks then usual and now today hot or cold will hardly start.. Ive had air dog raptor on it since 174k miles now its got 220k. Wouldnt think the injection pump would go bad if the pressure has been good for 46k miles any advice would be helpful trying to advoid spending ton on vp

hard to start now we have cooler temps. have checked out IAT , and volage is running at 5 volts. any ideas to why intake heater is not powering.

About a week ago the truck started being a little difficult to start. I would try to start and have to give it a second set of cranks to get it to fire. Previously to this it would start almost instantly. No I don't have my fuel pressure gauge installed yet but do have a low pressure light on a Hobbs switch mounted on the VP. When I have difficulty starting I'm seeing the light come on a little and flicker. Never experienced that before. If I reved the motor up to 1200+ rpm pressure would stabilize. Now I don't see any visible signs of a fuel / air leak. I changed the fuel filter to see if that would help. It didn't look bad and made no difference. I know I need to get my…

My truck is having a hard time starting. When idling the pump pressure 14. When going 70 it is 11. When trying to start it is 0. I now get the p0216 code and 1693 companion code. It is possible low pressure set off the codes so let's hope that is the case. The codes came a few days after the hard starting started. I have a new oem lift pump. 730k miles.

Hello again all so thought i'd toss this out there to get an idea of what the problem may be on our Work truck. So about 6 month's ago When my boss got his replacement truck. a 1998.5 Dodge 3500 Auto,4x4, 24 Val Truck. I went through it (When i could he bought it sight unseen for way more then worth with rust out the butt and not worth the price tag IMHO) But, I replaced every Fluid, Filter, Power steering pump, half the front end (Owners wife said it "like to wander" spent a few thousand replaced every part in the front end no help at all.) But after i Replaced the Fuel Filter, Refilled the canister as all way's with fresh diesel. .....The factory Fuel pump went dead... …

I just replaced my VP and although it starts much better, there is still the 5-8 seconds of cranking to get her going.... I have read that the fuel pump should not be running while cranking, but I'm pretty darned sure mine is...I don't want to hurt this VP. Should my FASS150 turn off while cranking and then pump once it fires up????I'm jealous of Mike's video where his truck fires in just 3-rotations....

Ok found out my truck is actually having a hard time starting with fuel pressure showing on the gauge. Never had this issue before and dont know how long its been going on.I have remote start and almost always use it. Until my truck gets to slightly under 1/4 tank. I have a bad cut DS so at times under 1/4 tank it will start then stall or not start till I prime the fuel system with the key bump trick. Well last 1/4 tank I remote started it watching the gauge. Started up as normal but seemed to take a bit longer to get FP up. Ok I says. No more remote starts till fill up. Next day I prime the fuel system first, it cranks a couple seconds then starts. Let it idle a bit …

My 1999 ram 2500 has a hard start, no start condition I have to unplug the pcm and ground wires to battery with the key on to get it to start and sometimes it goes to wto at start u. Any help would be appreciated

OK I posted this on CF. Thanks Mike for the tip on the Overflow valve. I just finished reading your testing on it and then rechecked to see you mention that lol. Quote is what I posted over there: I did some testing according to the bluechip diesel VP44 diag page and came up with it being a fuel delivery problem. Like I said I only installed a DSV replaced the supply line to the filter, cleaned the prefilter and replaced the walbro with another one, and redid the regulator. The fuel lines used to weep fuel and would drip ocasionally. It no longer leaks but now the hard starting. Used to fire up right away. Not sure if its in the tank, or the new line or? I h…
