Kj 2003 Sport Wrangler 2.8Lt CRD Cuts out at half way on temp gauge

[Bush_gal]

Yes, it is a 2003 KJ WRANGLER SPORT CRD 2.8Lt i live in australia, from my research i gather thats the export name. Also known as Libertys. Im thinking the problem is the alternator. My husband tested the battery this arvo, its losing current also worked out how to get the codes, they are: Coolant temp voltage to high,crankshaft timing misalignment,injector circuit current increase, inject current increase, cam shaft position sensor, air intake temp signal to high, boost pressure sensor plausability, ERG Solindoid excessive current. Will definately know by morning as battery fully charged tonight, if its flat by morning i know somethings draining the battery.

Ok.. now that make sense. Yours is NOT wrangler. It's the 03 KJ Cherokee.
No wonder it doesn't feel right reading the title and content.
KJ Cherokee (Aus) = Liberty (US)

I am not too sure what is causing it, but it does sound like air in fuel. One possibility is the seal for the filter. A stupid one would be forgot to take out old seal when replacing filter. :P I could be wrong. (most of the time)

It's better ask in the KJ forum or ask to move this post across.

Perhaps a mod could move/delete this thread and or put it in the KJ CHEROKEE part of the forum, then we can help out and leave the JK Wrangler owners alone...

When driving its running perfect, however as soon as it hits half way on the temp gauge the vechile shuts down and will not restart again until it has cooled down to about 1/4 on temp gauge, usually 10-20 mins later. we have checked, fuses,relays, sensors, battery,alternator,radiator,fuel. To no avail This has been going on for about 2 weeks, however the last 2 days when you go out to t the key, the battery is dead! Any idea on the gremlin we are chasing?

Ahhh now this feels better, a thread about a KJ in the KJ part of the forum, less BS now...

*A common issue on both the 2.5lt, early 2.8lt and the later 2.8lt diesel is the failure of the crankshaft position sensor, I'm now keeping them in stock as its become that common. The symptoms are as you describe, once it gets to a certain temp it cuts out and wont start again until cooler, about that 10 minutes or so.
*There are generally round two fault codes from memory, one is in ref to "camshaft" position sensor circuit, the other I cant remember, the early ones, again from memory cross ref the crankshaft sensor and camshaft sensor, when there is a mismatch it throws the camshaft sensor as the fault even though its the crankshaft sensor at fault.
*Other less common issues are a short in the camshaft sensor circuit, just after where the harness plugs into the cam sensor, the plastic engine cover wears through the harness, but the symptoms are more erratic as in sometimes cut out, sometimes not start, can go for days without issue, will generally fault code with a ref to cam sensor circuit, but wont be listed as "open".
*Fuel filter head leaking, but again symptoms are moving away from what you have said is occurring and again can be far more erratic.

*The other no start issue may point to a alternator clutch pulley failure, have a look at alternator pulley, generally if failed, failing it will have a fair amount of red rusty powder around it, so the clutch doesnt allow the alternator to spin at full rpm if at all and there for doesnt charge the battery.
*less common is a alternator failure.
*modern batteries tend to only last about 3 years at best, see how old it is.

Its a start...
