somtimes it will and somtimes it will not p1684 and e100.6,400.1,100.0----
wife coming home one day,said it just cut off at stop light..but started right back up...next day about a mile from house died and nothing will not turn over...so i come home from work look at it find a blown fuel pump fuse replace and dis-battery...fires right up....50 miles later dies while idling on me....cycle key few times fires up nothing for 100 miles so i give it back....dies at her work .....ughhhhh....long story short its here now when its not going to crank i can tell because oil light isnt on.. when its on it fires up....only had this thing 6 mths bought it because it only had 67,000 and thought it would do good ...any sugg ...thanks guys so much
in advance........laid off right now...need to do what i can...i have alot of tools....

 

could the anti theft be doing this or is that just the after result...today fired it up run great about 2 min---shut down---tach stuck at idle speed,turn off key and try again, red light will not go off just blink once after turning key on....no engine light or oil light they are at bottom of cluster......i have put new battery and fixed a better eng ground wire ,,,,didnt like the factory one...

 

the only real code was the 1684 there would be others if u used a scanner to see what they were b4 u replaced the battery if U check them after that battery was replaced your screwed and u will need to let a pro look at it then.

 

i did try to pull codes ,there was none ,,,,what do you mean by one real code .....400.1 = improper power shutdown
100.6 = 'SBEC/DEC/MCM communication failure'
100.0 = 'loop-back failure'

 

all of that info is generic there is no real data with those codes use a real scanner to get the codes

 

I too have the same problem, '03 T&C (115K) shuts off at idle or stop light but it would always start right up. My codes were & still are, P0442, P0455 & P0173. The first two I believe were related to some kind of air vacuum leak and the last one was regarding the fuel but can't remember, only that it was not something to cause this problem. I am waiting for it to get worst and for it to throw a meaningful code or someone here finds a solution. Sorry I was no help but maybe my codes mean something more than what I read at the time...?

 

I had the same problems and replaced the battery, the alternator and even the crankshaft sensor with no success. It turned out to be the main wiring harness needed repair/replacement. I chose to get it repaired at a significant cost. But issues went away.

 

Really? Wow! Was it damaged by wear & tear or did you have mice or something in your garage that caused the damage? I main wiring harness is a big job to replace but where would you even begin to repair it?

My issue is getting significantly worse. It use to shut off once every 20 mins or so but now is like every five minutes of idle time. I need to find a solution with out braking the bank.
