Liberty mpb4500 battery replacement? - Cars & Trucks

Needs the code removed from the computer. Go have it tested at Autozone, or some place that it is free, some will remove the code.

From your description it seems as if the relay is bad or else the battery is shorting out inside and needs to be replaced. I would change the relay to start.

check your starter,better yet has your alarm system been activated and possibly shut down your car a passive alarm will do that

Pull and clean all terminals on starter.

Either the battery needs replaced, or the alternator is not charging.

Chances are battery is in need of replacement. If you can get the battery out and take it to auto parts store, have it load tested.

SOUND LIKE DEAD BATTERY.CHECK BATTERY CABLE FOR TIGHTNESS AND FREE FROM CORROSSION AT BATTERY POST AND BATTERY CABLES.MAKE SURE BATTERY VOLTAGE IS 12.5 VOLTS.IF NOT BATTERY NEED CHARGING AND TESTED.IF BATTERY GOOD.SOUND LIKE ALTERNATOR BAD.BEFORE REPLACING OR DISCONNECTING BATTERY CABLES OR BATTERY AND ALTERNATOR.TURN OFF RADIO SO YOU WONT LOSE PLAYING CODE.

you should be ok the only problem you might have is if the stereo has a code on it then when you fit the new battery it may ask for this code

My wife had a similar problem with a 2003 Jeep Liberty. Her problem was that it stalled and she could not get it restarted unless it sat off for 30-45 minutes. It seemed like it was a problem with the alternator and battery but it had just gotten a brand new battery in it and we discovered the starter would roll over after the Jeep sat. We had it towed to the dealership and they replaced the Crank Sensor and the Timing Sensor and the Jeep now runs fine again. Side note: They charged us about $200 to fix these parts.

YOUR BATTERY HAS LOW VOLTAGE, NOT ENOUGH TO KEEP IDLE CONTROL VALVE OPERATIONAL. REPLACE BATTERY AND YOU'LL SE THE PROBLEM GONE.
