I am looking for suggestions regarding an electrical problem. The 2005 was running fine. I stopped for 20 minutes and attempted to restart, and everything is dead: starter, lights, locks, radio, everything. I couldn't get the faintest light or anything. Poked around under the hood, and went into the main circuit box by the battery and pushed every fuse in although none looked out of place. Still everything is dead.

After arranging for a pickup from my dead vehicle, I made an attempt to restart and voila, it started normally and everything worked. This is a one time deal, but now I am nervous.

Before my restart, I thought about the battery, but a battery failure would have had to been totally gone and suddenly which is not how they go. I am discounting a bad battery because it suddenly worked again normally.

The setup. This all happened a day after picking up at a dealer. I had the timing belt and water pump replaced; and all the glow plugs replaced. One plug was rusted tight, snapped, so the head had to be removed $$$ and taken to a machine shop for extraction. Came out of dealership after 2 weeks and all seemed well for a few days until I took a 600 mile trip and about the midpoint realized I had a diesel leak. Back to the dealer and a injector fuel hose (or tube?) was leaking which was repaired. Runs fine for a day until my power outage.

Since it is appears to be intermittent, I am trying figure it out without the hassle of another trip to the dealer.

A Battery's gradually dying - is old school

now - if the voltage won't turn on the computer - it won't start and that's not gradual it's a toggle switch (or more correctly it's the transistor turnon voltage).

you need to have the battery stress tested.

that's not the only thing that can cause it - but it's a common issue.

As stated...most likely the battery....there are numerous posts like this one and the battery was often the problem
However, as the Dealer probably removed the battery while working on the Jeep....check that the battery terminals are clean and firmly tightened and check the grounding wires grounding the battery and the engine to the chassis are clean and tight.

ColoradoCRD - I'll put a decent 6 pack on your battery having an internal intermittant short between cells. Years ago, not CRD, I experienced those exact symptoms. Key on absolutely nothing has power; 20 minutes later cranks and runs fine; all on a relatively new battery. I'd replace the battery. Not sure even a load test will ID the problem but you might ask a good battery or auto electric shop. A slowly failing battery might produce intermittant no start if it intermittantly has insufficient power to convince the ECU to grant permission to start the engine but if that's the case other things like radio, dash lights, dome light, etc will still work.

Performed load test on 8 month old battery and it checked out OK. Installed the original Red Top and it still works, by the way, but it had the same symptoms.

I bought a good multitester and was able to determine that battery voltage declined when the 05 Jeep was sitting, so I was able to deduce that I had a small drain on the battery when the engine was stopped.

I took to a dealer with my conclusion, and the Dealer confirmed a drain, and determined the source was a faulty Body Control Module which is located under the dash by the fuse panel. Cost of replacement module (Part No8035029) available on a rebuilt, core exchange basis: $361 plus labor
