No, I'm not planning a rash of PT Cruiser thefts.
I bought an '02 Chrysler Town and Country roughly one year ago, mostly for the AWD viscous coupling. Since then it's been sitting behind a building I own. Occasionally I'd start it up, but eventually the battery ran dead and I gave up that charade of caring.
Now I have a gent interested in buying the rest of the van. So last week I went to start it up again using a jump box on the stone-dead battery. Probably a bad idea with something that has so many computers.
I suspected the anti-theft system because it did start and run (twice) for about 5 seconds. The system allows this, but if it doesn't communicate with the transponder key, it shuts down (fuel I think). Then it was dead, wouldn't crank. No codes beyond P1684, "battery disconnected within the past 50 starts"
Today I installed a known-good battery and had the same no-crank issue. After following various procedures on the interwebs, still no crank. (touch battery cables together, lock/unlock with door key, etc.) For the hell of it, I invented my own... set off the alarm by opening it from inside, then shutting it off with the key fob. Success! Fired right up and ran great for a few minutes. Then I tried to restart. Two 5 second runs and no more crank.
Now I can't even get back to that point. The buyer only wants it for parts, but obviously "running" helps. I suspect I toasted something in the anti-theft module with the dead battery/jump start.
Is there a wire I can ground, a fuse I can pull, a resistor I can put between a wire, etc. to bypass the system? Again, the Internet is full of "suggestions", but nothing conclusive.
Thankee
