Car Won't Start after disconnecting battery

Asked by May 27, 2017 at 02:15 AM about the 2005 Jeep Grand Cherokee Limited 4WD

Question type: Maintenance & Repair

So I was coming down a hill and my heck engine
light came on so when I got home I disconnected
my battery to see if it still stayed on after
disconnection, I reconnected battery and my dash
lights came on and flickered for 30 secs but then
went blank I then thought my battery might need
charging so I hooked it up to my battery charger
and said faulty battery so I'm assuming it's my
battery ?

I then reconnected after 15 mins and my was
unlocking and locking and then stopped .

Car was doing fine before this only had a service a
week ago so I'm very confused and upset

Would it be my battery would jump starting it help it

I can't afford a new battery till next week and need
my car ):

Mines doing the same is your fuel pump working? Im not sure if its the problem but i kno it is a problem with mine

I don't know I litteraly was driving it fine all day got home unloaded groceries decided to do battery and now it's not starting and the battery charger is saying faulty battery like the dash lights come on and my inside car lights work but radio and key button lock aren't working . I've just had a service and safety check done last week and had a new AC compressor fitted so I'm freaking out

A battery that has went bad can have enough voltage to keep low load systems operational but not enough to crank the starter or other higher amperage draws, as this is an 05 I'm concerned about software corruption of the rig BCM, loss of accessories is the first indiacation of such a problem, before you remove the battery again, you need to hook up the preset saver tool into an operational power port, then replace the battery properly, make sure the cable ends are totally clean, no black corrosion, and then see if all is well, if it is still missing accessorie function then a trip to the dealer for a reflash in required. This started in 2005, my 05 Yukon has this system.

Yes I do agree with the battery problem, just be careful you don't want to spend another hundred bucks at the dealership.
