Dodge Diesel Question...

[Willl]

Get your batteries TESTED, a bad battery will test bad, no need to replace good parts.
God knows we don't need anymore "parts changers".

My 02 still cranking strong with the stock batts.

If one is bad REPLACE BOTH. The second is probably not far behind.

Replace the batteries...My diesel Suburban started doing the same thing and that was the problem. Sometimes the secondary battery will get corrosion on the terminals that can rot the wires under the insulators..Ran into that too. That's a fun one to track down.

Learned that one the hard way. We pulled, tested and reinstalled the 2nd battery (mounts inside the framerail even with the B pillar) in my parents '99 E350 15 pass Diesel van. Had to replace it a month or so later (when it was COLD and nasty out.

Never again.

As for the "pump looking thingy", could it be the windshield washer fluid tank and pump? Are you sure its a radiator tank?

Here'some pic's of it ... its right in front of the plastic tank and has the yellow/orange plug. When you turn on the key you can here that baby running and when the engine is running you can feel it running. I guess it just keeps running ...

Not sure, never owned a Cummins. Could it be a fuel pump? Has it always run like that? I am sure the guy at the parts store where you go get you 2 new batteries at can tell you.

I don't think its fuel related... Its odd I do not recall it running, but then again I have never had the hard cranking cold start so I could be looking and listening for problems ... I will let you know what the auto parts guy says.

You know, it may be brake related. My Fords have a electric motor to power the brakes. GM uses the power steering pump to give power brakes. Not sure about Dodge. The thing is diesels just do not make the vacuum to give you power assist brakes so you need another source of power.

Thats a relay.. Although you shouldn't hear it "running" Typically, a relay will "click" when energized and some will have an audible "click" when they are de-energized.
