Fuel System and Dead Battery

Asked by thrawn002 Nov 07, 2019 at 09:09 PM about the 2011 Chrysler Town & Country Limited FWD

Question type: Maintenance & Repair

So I did a routine front brake and rotor replacement on my Chrysler Town
and Country 2011. I have had battery issues for the past year, but not so
much until the cold weather starts to arrive. I decided to replace my
serpentine belt. Since I did that, it seemed that the vehicle ran much. much
better. When I arrived home from my friend's house, about a twenty minute
drive, it sounded like my fuel system, located to the rear and underneath the
vehicle was running loudly, after the key was removed. 30 minutes later it
seemed to be getting much quieter. This morning my entire vehicle was
dead. Any suggestions? I do not know where to place the blame or point my
finger, as far as the culprit to the lost power.

sounds like a parasitic draw test is warranted. To do this without the use of a multi meter and you suspect it is the fuel delivery aspect causing the short. disconnect the negitive battery cable and with the use of a 12v test light connect it inline by connecting the clip end to the post and the probe end to the cable removed. any draw of electric will cause the light to illuminate. You may have to also pull fuses that normally draw power when the vehicle is not in use or key is not in ignition such as dome light, cigarette lighter and radio. If the light is still lit pull the fuel relay and see if the light goes out. If it doesn't it may not be the fuel system causing the short draw. Pull one fuse at a time until the light goes out and that is the circuit causing the short or battery draw.

Stuck fuel relay is a known issue with some years of the town and country. My 2012 has it. There was a recall and a fix for older models but it did not cover mine. Nonetheless, I did a websearch and found a couple videos of how to work around the problem. Applied my work around in 5 mins. Not sure if allowed to post a link in here...but you can find it.
