2nd Generation Dodge 24 Valve Powertrain

Currently running LT265/75/16E Mich M/S. Dodge recommended LT245/75/16E. Poor fuel mileage towing 8000lb Tag Along Travel Trailer. How much in safety am I giving up if I go to LT235/85/16E A/T in hopes of improving fuel MPHs? 2001 Ram 2500HD Diesel 4sp A/T. Have done the Banks Power Pack deal and A/B Cold Air Filter with no increase in MPHs.

Ok gang I got vp 44 installed and now shifting is grate, no rpm drop, now shifts nice and smooth. But, there is still a problem with shurging when slowing down or push clutch in it surges about 4 times then smooths out. I put new timbomb apps and the lowest we could get numbers down to are .671 is this to high, in other words is apps sending a message to ecm searching for idle mode? Tim said .671 would be ok, I am wondering if there may be a problem here. Oh yea, eng. died several times with old vp and never thru a code. I got to ask what's up with that?

New to Forum. Saw the Scan Display II in the article about MPGs. Where is the best place to get one price wise?Mohok

I have an 01 dually,that I bought from my mother after my dad passed away last year from brain cancer. The truck had sat for about 8 months,and after I had driven it for about 4 months,the lift pump failed on the way home from work,and the truck died and I had to tow it home. I replaced the lift pump,but I still couldnt get it to crank and run, it was getting fuel to all but the #1 cylinder. I checked for trouble code but it didnt display any,because the engine light wasnt on. I bought a lift pump and replaced it. I still cant get it to crank,but I did get some codes this time,they are P-1693,P-1689 @P-0122. Is there something I did wrong or something else wrong with the …

I have a 99 5.9 with a low pressure fuel pump not working. I changed out the pump today (160 bucks)with a new one but still no work. I ran out of time today to check voltage on the pump but I think it is a shoe in that it is not getting voltage during crank. I tried the bump engine but don't start, to hopefully get the low press pump to initiate but it will not. I did get the pump to work once a couple months ago and I think it happened when I drained the fuel filter through the bleed valve on the filter. Then went back to crank and the pump initiated. When I swapped out the pump today the filter was drained but it still did not initiate. All of that leading me to believe…

I am about to put in my 4th computer, the first was used and installed a few years ago, the 2nd was new from cummins, Aug 08. 3rd new from cummins Feb 09, and now it's time to install another. Cummins won't warrantee them because they don't show any codes??? I am running a hypertech reprogrammer, usually set to stage 3. When it runs it runs great but i cannot find anyone who can tell me why it keeps trashing the computer. Has anyone else had this problem or am i the only one?

Hello, I am about to install a Air dog 100. I have purchased a big line kit from vulcan performance with the tapped elbow. So I can run a a needle valve and connect a grease gun line to it then to the electric fuel sender. I know alot of people by pass the filter heater cannister. How do you think it will perform. I know there will be another filter in the mix. I read a post on another site on a install like that. In the post the user cut the filter and used the o ring from the top of the filter. Any opinoins will be appreciated.Thanks,John

Ok, I am very curious on this. I have seen Cummins videos online and I began to notice that when I turn my key to "run"(engine off), my oil pressure goes up to full operating pressure and not one other truck in those videos have. I'm aware of pre-oilers but I have not seen anthing unusual about the oil lines nor any pump sounds before or after start-up or shut-down. Any ideas?

I am a retired maintenance mechanic so I am pretty knowledgeable but my question is everybody around here wants $300 to install a vp44 is it that hard or can most people do it.The one thing that concerns me is the keyway falling into the case.Also can the pump gear get off the cam gear while you are doing this.And also is it hard to line up the pump with the keyway.I watched a guy do this on utube and it was a really good video and he shows what to do and not do.

Hello. I changed the pinion bearing on my 1999 dodge 2500 cummins. and i put back the shims that has been there. and if i tighten the pinion nut it will not turn. My question is if all the shims was put back in place and i over tightened the pinion nut should the pinion still turn? or i have to have it torqued right? I dont have a 500 torque wrench. or should i buy a shim (between the yoke and outer bearing?. I need to fix my diff in2 days the garage will be used after that. thanks in advance for any help. espanton@telusplanet.net

Ever since I've had the truck, it's only had to barely crank once to start the engine. Now it has to crank 10, 15 sometimes 20 times before it will start. It runs fine after starting. I have a two year old Blue Chip VP44, a new lift pump and good fuel pressure and have hand over handed the entire fuel system looking for leaks. This includes: injectors, supply lines, return lines, banjo-bolt o-ring seals, fuel line steel tubes to hose connections and have detected no leaks. I have no codes showing. A fellow Cummins owner thought it might be as simple as a faulty fuel cap not venting and drawing a negative pressure on the tank, causing the fuel to syphone back to the …

everyone knows the CTD is quick, but in my pursuit of quickness i have noticed that when i get to ~2600rpm there isn't a lot left.... i would thank that my fuel rate is dropping, but i have an airdog 150.my truck is completly stock except for the dog and a "boost elbow". i have a 1999 2wd 2500 5speed.is it just me or is this normal for the cummins?thx for the helpbryan

Got an 01 dually,replaced the lift pump, still no crank,tried the code display it displayed the p pcu then p done then p ecu then p done but no code inbetween either. Got a $300.00 code scanner on the recomendation of another tech, showed no code stored because check engine light not on. I am stumped as to the problem with my truck

I have a 98.5 auto, stock 24v with no start condition last week. Wasn't getting fuel but started after about 20 min. I changed fuel, air and oil filters and primed it. Started fine but no start next time. 50/50 start/no start over the next week. If the lift pump would prime by bumping the starter, the truck would start every time. Did a lot of stuff suggested on here and other places with no luck. Finally pulled no 9 fuse and ASE ? relay and cleaned bayonets Truck has been starting and running perfect the last 4 days. Any ideas?

To all; I have been having trouble with my 2000 2nd Gen, The truck was shifting strangely, I was getting what I thought was "dead pedal". I perused the board for answers to others questions/posts. I could not get more than the 1693 code from the odometer readout...no matter how many times I did it...sorry Michael, I just couldn't get it!So far I have done the following, and the problem comes and goes.1, I removed and cleaned ALL the grounds in the system, and the battery leads, and the fuse/relay box leads2, I have replaced the Carter pump with a Fass replacement pump, just because and I have 153000 on the truck3, I have replaced the APPS with one from Timbo. 4, Today I w…

MY 2001 temp runs between 195 and 205 degrees. I changed thermostat, took radiator out flushed it and cleaned it and degreased it. Thought it might be running warm cause of blowbye blowing on radiator. Radiator schrouds were in good shape so im open to any suggestions. Thanks

Replacing the vp44 should I replace the cam sensor too as it is easy to get to with the vp44 removed.

MR. Mopar what can you tell me about jet fuel?? Can we run it in are trucks? THANKS BEN

Well here we go. I have a AFE intake filter stage 1, a friends idea is the stock filter is better then the AFE, in that it is not sealed good enough to keep the hot air from the engine from being sucked in,and that these type of filters itself will get pin holes and allow dirt in, thus losing horse power, were as the stock air filter draws from the cooler air in the fender and do not get the pin holes, any thoughts.............thanks

Is it time for a new pump and where is the best place to get one.98.5 24 valve 3/4 dodge with five speed.1693 code with 1691 that could only be caused by pump failure right.
