  2. Hey guys, I had a problem come up on my 99 on Friday. I came out to start the truck after it sitting for maybe 4 days to go dirtbike riding and the truck started at first, I moved it to the spot I load my bike and then the truck wouldn't start when I went to leave. I watched some videos and did some reading and got the truck to start by unplugging and re plugging the connector right out of the fuse box with a single brown wire. No loose battery connections and just looking around I couldnt find any loose grounds anywhere. I took the truck and it was fine the rest of the day, started fine probably 5 times. Today I went out and it happened again. No crank, clicks every time…

    I've been reading all the ecu/pcm/vp/sensor/alternator failures over the last few months on here and getting more and more paranoid by the day as over here in the uk no recovery is available for my 5th wheel and I doubt any recovery/breakdown co would touch the truck either. So my question is would a 01 ecm work with a flash on my 98.5 ? I have sent acs a message on this also. Also going to try and locate a spare pcm and maybe a new alternator and whatever else I can think of I've done the WT mod. And also Mikes alt protection

  4. Hey folks searched on here but didn't find the answer I was looking for, most likely user error. About to install an auxiliary trans cooler with fan under the bed, mostly for slow 4x4 driving. I live in Nevada and it gets hot. I've got a Mishimoto replacement cooler up front. I drew three hunt tags here in Nevada and with 333K on the clock I want to help it out a bit. I wanted to double check that the return line on the transmission is the rear line as it attaches to the transmission, correct? #3 in this image. Thanks in advance, Adam

    02 3500 nv5600 2wd quad cab. 233k. I've been as diligent as possible regarding preventative maintenance, but you know how it is, entropy is a ***** and things go wrong. Now getting ready to put down some serious miles - long distance cross country driving soon, multiple times this spring and summer from NJ to Florida towing a haulmark 20ft car trailer (approx 7,000 gvwr). Here is a list of the repairs i've done, as well as some pro-active maint in anticipation of major highway miles. Is there anything else I should do? Thinking I've got the major failure items covered.. Is there anything else that's know to fail on these 2nd gen…

    So I bought a 2nd gen, had high miles on it and could tell had been sitting. Upon buying I started having troubles, after driving it home 6 hours away I started trying to get it back to 100%. Narrowed down the first job to being bad injection pump, so I bought a new one and replaced it. Seemed to have fixed the issue and was running good, the truck doesn’t get driven daily it’s my farm truck, I started driving it a lot in the last month and when driving the truck is fueling really weird. #1. It does have hard start after sitting over night. After that starts fine all day. #2. When driving and maintaining speed say 1700 rpm you hear the turbo and fee…

    So to start here’s what I’ve done to try to fix it. Checked all grounds and connections, new batteries, new timbo apps. I don’t have any fuel pressure gauges so I don’t know if it’s a fuel thing. I am looking to get some today if I can. So the problem is once I get to about 43 it starts surging. It will stop as soon as I go back to 40 or under. The problem seemed to appear after I replaced my whole A/C system. And only when the Ac is on. But will keep happening even after the AC is turned back off. But if I never turn it on in the mornings, it doesn’t seem to do it. Although I never get too far about 15min before turning it on because of the heat here. It seems like when …

    Hello, at the risk of being redundant on the forum, I drive a 98.5 24v with a 5 speed manual. About a year ago I started having a slight stutter at idle. It’s not hard, just enough to to feel and hear and it’s very erratic and only when the engine is at operating temp. At the time I was seeing some metal shavings in my fuel filter housing every time I would change it so I attributed it to the lift pump. Within the last month I changed my lift pump to a FASS 165, afterward my truck developed a hard start issue. Due to the fact my VP was original to the truck and I figured my old lift pump had warm enough to have low fuel pressure, I replaced it with a…

    Hello all. I have a 99 dodge, the truck has a 2002 engine that has been installed, after the ‘53’ block died. The truck has a tone wheel mounted to the front of the balancer for the ckp sensor. The truck has the HO vp pump and the computer for the 2002 engine. the issue I’m having is a p1690 and p0338 codes. The only issues the truck seems to have is a miss or stumble at idle that seems to come and go, and high egts. I have recently replaced the balancer as it was coming apart, reset the air gap on the tone ring to the sensor and Cleared codes and they come right back. looking for recommendations on where to go next. tr…

    Hi guys, I understand this topic has been beat to death but I have had the following issues with my 98 2500 24v. Over the last two years I have had random codes pop up with no performance problems (low voltage related to apps sensor) had them cleared 2x about a year apart. Did hours of research and the common thread seemed to be a failing apps sensor (no dead pedal up to this point) So i bought a new bell crank assy to have on hand in case. About a week ago it happened dead pedal, when I pulled to the side of the road it went away. So when I got home I replaced the bell crank/apps assy asap. Been driving it for a week without issues yesterday when I was deceler…

  13. Truck decided not to restart once Saturday, started Sunday and died once, one restart since then. No rhyme or reason. but. . . I have 8 volts on the grounds at the Aux. battery for the PCM and ECM. Disconnect them with the key on and everything comes on like normal but no start. (no voltage on VP pin 7) Reconnect and it will start. (voltage on VP pin 7) Will restart everytime after you disconnect and reconnect grounds at Aux. battery. Any thoughts?

  14. So my pinion deal decided to throw gear oil all over my truck last weekend so I’m replacing it. 2 questions, first any tips on getting this seal to come out? I’ve been working at it with a hammer and screwdrivers and it doesn’t want to go. Also, not sure of the name but the input Shaft of the differential has a LOT of play. It’s moving around a ton when I’m going at the seal with the screwdriver. Really hoping this is normal, needing a rear end would not make me happy. I took a video of the play but I’m not sure how I could get it to post here. It’s moving quite a bit, though. Any advice is helpful, thanks!

    Okay, fellas I need some help understanding what I'm seeing here. Over the past several drives, when I first start the truck up the BRAKE and ABS lights might stay on for a short bit (less than a minute) and then go out. Once or twice, I also caught the speedo popping up as I started to drive. Like it was at 0, then suddenly popped up to whatever speed I was going, 20-ish MPH... I wasn't really watching it, so I'd sorta see it happen just outside of my view. Then today, idling for about a minute in a parking lot, about to leave, the NO BUS message appears in my odometer, the MIL, ABS, FUEL and the AIRBAG lights are illuminated, and I lose my gau…

  16. Hello all, I have a 2001 24valve Dodge ram 2500 automatic. Wonder if my vp44 is bad. Today when driving, on acceleration I got a really bad stutter/cough in the engine. I double checked the voltage on the timbo apps and it is in spec and no dead spots. On the raptor pure flow the fuel pressure is 15psi at idle and around 12psi when accelerating. I have changed the alternator, it's in spec, I even disconnected fuse and harness to isolate if it could be that and it didn't go away. On low pressure side of vp44 primed to make sure no air on that side. No error codes and at my wits end what to do next. attaching a video if that helps. any thoughts…

    I have got a weird problem maybe one of you can chime in with a answer on my predicament. I have a 2001 3500 5.9 with a starting issue. I already replaced the IP and got it started with the help of Doug from Blue Chip following his directions. However, it will only run with the C3 wiring connector unplugged from the PCM?? It has np power and the odometer reads NO BUSS due to the C3 plug unplugged. I am trying to trace the wires from the PCM in the C3 wiring and have not found anything yet. How would I know if a wire is bad on one of these wires? Also could it be something else? Any suggestions would be appreciated!! Thanks! Steve

  20. Well I have finally came up with a solution for the dreaded torque management that has plagued us 2nd gen owners for decades, and best of all its free. It all happened by accident actually. I opened up my trans due to some funny shifting issues and found every screen inside it was full of metal shavings. Which obviously meant that they got past the filter but more on this later. I cleaned all the solenoids and sensors of the metal and the little screens that protected them along with installing a new filter and fluid. Everything was good for about 2 weeks then all of a sudden after i left a drive thu i lost all forward gears. I messed around with it for a little while (li…
