#631 of 642 04 2500 ram pull start only by gast Oct 14, 2009 (4:51 am)
I have a 04 2500 cummins manual trans . It turns over fine with adiqite speed to start but wont. If we pull start it it fires right off. After its warmed up the same problem still persist. Will only start if its pulled. When it starts it runs fine. No check engine lights. Have not checked for codes.

Even if only one of them is low on voltage, you will have enough juice to run the engine and all the electrical accessories, but not enough to start the engine (that's why it needs two high-output batteries - just to get the engine started). The old mechanical 12-valve Cummins that was used until early 1998 could run without any electricity once it was started.   If the batteries test ok and the problem persists, check the cables and starter.   kcram - Pickups/Wagons Host

Replying to: gast (Oct 14, 2009 4:51 am) My guess is a Cam or Crankshaft position sensor. By pull starting it you my be turning the engine over faster than the starter therefore allowing the sensor to read and communicate with the ECM. This is just my guess. Let me know what you find out...   Randy
#634 of 642 cummins smokin by warlord3 Nov 06, 2009 (5:36 am)
last week our 08 3500 started smokin, black, huge clouds, and progressively worsened with a tapping or clicking from engine. replaced an injector from cummins, but no change and looked like now fuel in oil. pulled replaced injector and one next to it for compare and they are different size at seals. Also looked at the modulator valve on top of charge air piping and it was completely garbaged with soot and not closing completely. suggestions?

Replying to: kcram (Mar 11, 2009 4:28 pm) How do you know a new, or newer D2500 4x2 with the right options, 6.7L will "easily do mid 20s highway"? I've been shopping for the last of the 5.9 models, 2004-07 with the 325hp motor in an attempt to get the best stock power and economy. But I'd gladly buy a new or newer one if I knew it could get the xlnt mileage of an older 5.9. Please advise, because most of the forum talk is against the newer 6.7, both on mileage and reliability issue. By the way, my friend has an early 2004 D3500 dually 4x2 w/ 4.10 rear, an Edge plug in module, and it gets the best I've ever seen, 23.4mpg at 65mph easy going freeway. Thanks.

#637 of 642 What year Dodge Cummins gets the best mileage? by thedesertraven Nov 08, 2009 (3:45 pm)
I'm not preferring an older one, say pre-2003 body style change, I've had many of those already, but I want to get a new or newer one that gets the best mileage. And I LOVE my friends early 2004, it's a 6 code(the eigth digit of the VIN is the engine code) with the 305hp, a D3500 quad cab dually long bed, 4.10 rear end, an Edge chip, and is just the smoothest, strongest running thing you could imagine, and great mileage, up to 25 on the freeway at easy, easy cruise. I've heard so much bad about the newer 6.7, and all the added smog stuff, and I DO know my newer Winnebago motorhome gets easily 15% less mileage with its post-2007 diesel engine technology. So I'm thinking 2003-07 might be my best best. Again, I'm easy driving, so MILEAGE is my number 1 concern. What is your experience?

Replying to: thedesertraven (Nov 08, 2009 3:45 pm) What you smoking? I have a 04 3500 4x4 with 3.73 gears and can't get 15 mpg with a til wind. It has power, runs good , all that but poor milage. Are you using the built in measure system or your own calculator? They EXAGERATE. But the new Dodges sound like real problems. I am leaning toward a Chevy 4x4 dually mostly for the independant front end. Replies to this message: kcram (Nov 09, 2009 12:27 pm)

Replying to: thedesertraven (Nov 08, 2009 3:36 pm) It's the axle. Your friend has a 4.10 - the worst axle for fuel economy. Dodge offers a 3.42 with both the manual and automatic... get a Cummins with the 3.42 and the 68RFE automatic (with the double overdrive) and you would have no trouble getting 25+ mpg.   kcram - Pickups/Wagons Host

Replying to: ramcharger (Nov 08, 2009 6:22 pm) I have a 2005 3500 Quad Cab 4x4 dually with the Cummins, 48RE, and 3.73s. At a steady 55 mph, I have no trouble reaching 21 mpg (real, not from the overhead readout)when the truck is empty.   You didn't mention which transmission you have, and that will make a difference, as the automatics have a more economical overdrive ratio than the manual (either NV5600 or G56). You also need to keep an eye on your air and fuel filters as well as your tire pressure, and make sure you use a good grade of diesel. While the engine will run on cetane of at least 40, if you can find higher (42 and up), the engine will be much happier. I definitely get better mileage with 42 over 40. Also be careful where you buy fuel... a small local station that might not sell much diesel runs the risk of fuel contamination underground; a station that sees a lot of heavy truck traffic and turns over fuel more often is the place to go.   kcram - Pickups/Wagons Host
