Hi All, I have just joined this forum and found it very informative and very helpful.
Hopefully someone can point me in the right direction with this one.
We have a 2004 Dodge Ram 3500 with the 24v Cummins engine fitted and it has allsorts of gremlins with the electronics. The truck has been stood for 12 months (elsewhere) or so and was believed to be running (although not very well) beforehand. The batteries had gone flat in this time.
We have charged the batteries off the vehicle and refitted them. (both seem to be holding charge fine)
Things that DO NOT work:-
1. keyless entry
2. Fuel gauge and volt meter
3. Diagnostic (on-off 3 times does nothing)
4. Warning lights come on, go out and come back on one at a time with a chime for each one.
5 Fuel pump is not constant, it pulses. (have tried testing the feed and the feed is pulsing) The injectors can be heard pulsing also.
6 Key in door lock will only unlock the drivers door, but the button on the door panel locks and unlocks all the doors.
The engine will spin over but will not start. (Not tested for fuel at fuel rail yet)
The vehicle Vin has been checked at a Dodge dealer in the US and it has been confirmed that it does NOT have the "Sentry" key system fitted.
All the fuses and many of the connections and grounds have been checked.

Any ideas anyone?
Any suggestions would be gratefully received. ( before I start stripping it down)
Have heard that I might have to unplug the instrument cluster and plug it back in while the batteries are connected? any truth in this??
Thanks. John.

MMMMM I know someone else with an 05 with the exact same problems except his is running.

I sent him to my dealer which is only a week ago.

There was a recall for shorts or a bad cluster or something like that. He had it done at a different dealer, his nightmares have been since. He went to my dealer, who has a noted service department, and they apparently fixed it. But I will try to confirm that.

I suspect the wire harness or a plug has failed.

What state are you in? My dealer is in Jersey. You bought this new???

Hi, Thanks for the info.

I am actually in the UK ! and we don't really have any dealers here.
I do have a repair shop, but wanted all the valuable input from you guys before getting heavily into it.
Please let me know what happened to the other truck.
Regards, John.

My pleasure.

He's a contractor working on my house and drewls every time he sees my truck.

I'll try to get some details from the dealer too. The parts manager and service writer have become close personal friends. That helps when you have mods on your truck. :lol3:

I Left My Truck Setting For 2 Years. I Had Hotshotted With It And Tore The Trans Out One Time Too Many Then Went To A Freightshaker. When I Restarted My Truck The Batteries Were Dead But Charged Fine. The Only Problem I Had Was With The Connectors On The Tail Lights. Corroded Real Bad.
I Would Clean The Terminals Going Into The Fuse Box First And Then Start Chasing Down Ground Wires. Anything Diamler Built Has Bad Grounds. Pull Out And Reseat All The Fuses And Relays. Computers Rarely Go Bad. It Is Usually Grounds And Connectors.

Ram electrical

Thanks for the info Dieseldale.
I have had the fusebox out and checked and cleaned the connectors underneath. They looked quite clean.
I have checked several of the engine compartment earths, but will have to start checking ALL the earth points. Luckily I do have a wiring diagram that shows most of the earthing points.
It will probably take some time, but I will post any progress I have.
Thanks again.
John.
Would appretiate any other ideas too.

Electrical gremlins

Checked all the fuses several times now. Checked all the earth connections in the engine bay, on the engine, on the transmission and as many earths as I can find behind the dash and around the cluster.
Still doing all the previous faults. I have contacted (via email) an ECM repair specialist in Florida to ask if these faults can be caused by the ECM and if they do a "checking" service if I sent it to them. Not had a reply yet.
Next I am checking my wiring diagram and will be testing live feeds to the instrument cluster and to the engine ECM.
Will keep you all posted. :$: :CRY:
