#525 of 641 Re: 2009 Dodge Diesel [murphy4] by kcram HOST Mar 11, 2009 (4:28 pm)
Replying to: murphy4 (Mar 10, 2009 9:11 am) Depends on many factors... - rear axle setup (2500/3500 single rear wheel or 3500 dual rear wheel) - cab (regular, Quad, Mega) - drive system (4x2, 4x4) - transmission (manual or automatic) - axle ratio (3.42, 3.73, 4.10) - usual cargo load (empty/commuting, loaded/work, towing)   The best: 2500 4x2 regular cab, 3.42 axle, automatic. Traveling empty, that truck will easily do mid 20s highway.   kcram - Pickups/Wagons Host Replies to this message: thedesertraven (Nov 08, 2009 3:36 pm) kcram (Nov 09, 2009 12:18 pm)
#526 of 641 2006 dodge3500 ram by nascarcamper Mar 14, 2009 (5:33 pm)
I have a 2006 Dodge 3500 ram with the 5.9 cummins deisel in it, with 20,000 miles on it . I pull a 32ft travel trailer with it . It pulled great until it went into the shop last summer and the dodge dealer put a ecm upgrade in it from cummins. I now have NO power to pull the trailer and I used to get 15mpg pulling the trailer,now I get 10mpg. The dealer replaced one injector and rebuilt the transmission. It did not help. Does anyone esle have this problem or know what the problem might be . The dealer said they can not reverse the upgrade.

Replying to: dodgeram94 (Mar 03, 2006 12:06 pm) Hard starting, Cummins is the bet starting engine there is, I would suggest that the fuel is running back to the tank
#529 of 641 97 ram starting problem by sheppardbs Mar 26, 2009 (2:24 pm)
slow cranking...will start...happened after lending truck to a friend, he forgot to "wait to start" and after the third or fourth time the truck starter began dragging ..?? Replies to this message: kcram (Mar 27, 2009 6:13 pm) sheppardbs (Mar 31, 2009 3:54 pm) kcram (Mar 31, 2009 5:06 pm)
#530 of 641 96 Dodge cummins diesel hard to start & stalls by def90 Mar 27, 2009 (1:06 pm)
All, I have a 96 2500 with over 300,000KM on it, and excpet some rust (Ontario) it has been an excelalnt truck. It has just sat with minimal use (max 1 trip per week) for the last 10 weeks. When I got back to it I ran it on a 25km trip, no problems then disaster struck. It stalled on me, was hard to restart(cranked but wouldn't fire) and got progressively worse. I replaced & bled the fuel filter, no improvement! I next suspected the transfer (lift) pump & have jsut replaced that. It still starts if primed, runs if throttle is held at 1250RPM or above. If I let of the pedal it will eventually stall out. If I prime the fuel pump & start & let it run on idle (750-900 rpm) it will run for approx one minute. I see no obvious leaks or damaged fuel lines?????? ANY ADVICE GREATLY ACCEPTED!!!! Replies to this message: red777 (Mar 27, 2009 6:13 pm)

Replying to: sheppardbs (Mar 26, 2009 2:24 pm) If it's still cold where you are and you have the block heater, plug it in overnight and see if it starts any easier.   When my 96 Cummins was slow to start, it was usually a progressive thing over time and was always the batteries giving out. But I was religious about waiting for the grid heater, and even a couple of ice-cold starts by my dad had no lasting effect on the starter.   Best guess is batteries - the cold cranking may have worn them out. (Remember, the 12-valve Cummins is completely mechanical and once started, requires almost no electrical draw once the grid heater has stopped cycling.) Second would be a worn starter, and if so, you probably want to get that replaced as a matter of preventive maintenance.   kcram - Pickups/Wagons Host Replies to this message: sheppardbs (Mar 31, 2009 3:54 pm) kcram (Mar 31, 2009 5:06 pm)

Replying to: def90 (Mar 27, 2009 1:06 pm) 2 things: 1) the camshaft sensor is going bad, you have a limited amount of miles to move it before it will jump time and destruct, really bad thing to have happen. 2) where the fuel lines come out of the tank, 2 copper fittings that your factory fuel fittings plug into will rust and suck air, with it not running at idle only at raised rpm i would suspect you are sucking air somewhere in that area. if its not the top 2 fittings its in the lines right after it. leaks are hard to find because of how dodge ran them in the c - channel of the frame around the tank. fuel will leak into the frame and usually has to run the length of the frame to underneath the cab before it finds a hole to leak through.   i would check the lines and if you are 100% sure you are not leaking fuel, then i would have the camshaft timing sensor checked. it is located on the front of the motor with the timing gear, it is a pain in the ass but if its broke it has to be replaced or the engine will jump "time" and destroy itself. . . then it gets real expensive.   hope this helps   -Red
#533 of 641 04 Dodge 3500 w/cummins by ramcharger Mar 30, 2009 (9:25 am)
i just purchased this truck. It's a 4x4 automatice 4dr dually. i noticed a comment today that got me wondering. 04 vs 04.5 What's the difference? How do you know which you have? I don't know the rear gear, but with stock 235/80/17's I'm turning around 2000 at 70. The fuel milage is poor in my way of thinking. I see others have the same questions about milage. Anyone had first hand experience with Bullydog stuff. Considering it. Thanks Replies to this message: kcram (Mar 30, 2009 4:26 pm)
#534 of 641 oil color by ramcharger Mar 30, 2009 (9:40 am)
Does the oil change to black quickly in Diesel engines? I just bought this 04 Dodge and the previous owner said he just changed the oil. I drove it 800 miles home and the oil was black as coal. I changed it and the filter. The oil went black again almost immediately. Is this a concern? Can I clean out the engine? Thanks
