Question about 2001 Dodge Ram 2500 Truck

2001 dodge 2500 diesel 24 valve intermitant hesitation

While driving at a cruse speed the engine RPM drops in half,still runs even,but lacks power.let up on the throttle, then mash down again and it usually picks back up again.The engine light is not on and does work. This problem is not an every day occurrence.some days it doesn't do it at all,some days its bad.lift pump has been changed,with no difference.I am curious about the throttle positioner or the module on the inj. pump.

    Sounds like I have a similar problem, only RPMs on guage are not dropping all the time. I have noticed on the bad days when you take foot off throttle, hesitation stops which makes me think it may be a sensor in the throttle itself, fuel pump has been replaced as well as injector pump. Filter doesn't seem to be the issue either. Hope someone knows what the problem is, mechanics in my area don't seem to have any answers.

    I have replaced the lift pump and nothing has changed. I was thinking it might be the throttle position sensor ?? Any more ideas??

    I have a 2001 dodge ram that has the same prob. MIne has 178,000 miles on it and had done the hesitation for quite some time now. Hook the code machine to it for no answer! The enguine goes flat with no power but turn the key off and right back on and you got power! Once the truck warms up it seems to be fine. Also I have noticed that with more than a half a tank of fuel the problem does not occur as much. I want help and I know you guys do as well !--Marc Savoy , Texas

Have you ever had the mechanical lift pump go out on these vehicles? If the fuel pressure drops under 5psi on the VP44 injection pump for any length of time, the diaphrams get weakened and especailly when the warmer seasons come back, you will notice fuel delivery problems. A new/rebuilt pressure pump is required! Sorry for the bad news, if indeed this is the case. One solution/prevention is to replace the lift pump with the upgraded Mopar (goes into the tank now) or an aftermarket pump like the FASS pump or the like. Anyone that has the VP44 injection pump should upgrade ASAP! This is a common problem on the OEM mechanical lift pump on this particular run of Rams. Need to do it before you run up a costly repair bill later on down the road. The stock/OEM lift pumps WILL go out, sometimes as little as 12k miles, sometimes 50k miles.....I had 3 go out, Stock at 43k, Mopar replacement lasted 31k and the 3rd (aftermarket OEM) lasted 14k. I had a fuel pressure guage installed a very long time ago to alert me of failures. The 4th go around I installed the FASS and now it maintains 21 to 27psi even with chip mods switched to extreme! I am still on original VP44 pump (knock on wood!)
Good Luck!

Have you checked the PCV system?? If its stuck in the closed position then you will lack power and turbo boost. A vehicle needs 3 things to make it run proper; FUEL,FIRE and AIR. Try that and see if it helps.

I have a 2001 Dodge Ram 2500 Diesel Truck. First the radio quit working. Then the Cruise-control stopped working. on top of all that it sounds like the transmission is slipping. The motor keeps jumping...


The radio and cruse are probably the steering wheel connector . Cannot remember the name but it conects the control buttons to the harness that is if you have cruse and radio controles on the wheel also the transmition has issues in those years but I have found that it is often caused by sensors TPS sensor , will cause irratic shifting also check your fuses for any bad ones this can cause your reader not to work . I love the Cummons engine but hate Dodge trannys I own a Duramax because of the Alison tranny if they made a Cummons Alison combo truck that would be sweet good luck

Transmission- 2001 Dodge ram 2500 diesel 4X4


I have a 2002 Dodge Ram that doesn't like to shift into 2nd when flooring it from a Stop. Imagine if you were to floor the gas in neutral, the engine REDLINEs and the engine governor kicks in to keep the RPM from blowing the engine......while stuck in first Gear. If i let off the gas, it goes into 2nd fine. I have replaced the Speed Sensor on the transmission ($18) and it seemed to fix it for one day. After 200 miles, its doing it again. ANybody have legitimate answers in here? Its only got 60K miles..wtf?
