Battery died and was recharged but jeep will not start

Run this by me one more time your Post doesn't make sence. Is Battery light on? Is alternator working properly 13 to 14 Volts You Must have a fully charged Battery to test. Get tested at your Local Auto Parts Store after charging

Immobiliser fault, disconnect battery from poss terminal for 15 seconds, reconnect battery close hood and doors lock car with fob wait 20 seconds open car and start car.

If it did not start and die when you used starting fluid then check to see if the plugs are getting spark. Check to see if injectors are pulsing. Could be bad crank sensor. Need scanner to check further

To run the battery down over night, points to a pretty good drain. At least a light left on, it should be easy to determine if that is the cause. Don't forget the light under the hood, in the glove box, and in the trunk.

Another problem may be a good battery, getting poor recharging. The battery may start the car fine in fully charged condition, but if the alternator is not putting out the proper voltage and amps, it will not only not recharge, driving the car will continue to discharge the battery. This often is not noticed, until you turn off the car, and cannot restart due to a low battery condition.

Do not overlook the battery cables. Often they look fine, but if there is a small amount of corrosion between the positive battery cables connection at the battery, that will create a poor connection for starting, as well as a poor connection for the alternator to resupply the battery with electrical power. Remove and clean to bright metal ALL battery cables and clean ALL of the ends. Be sure to also clean the battery terminals to bright metal condition, and be sure to clean, or replace, the battery terminal bolts.You may also want to take it to autozone they will put it on a diagnostic scanner for free and that may also help you narrow down your problem.

Test for fuel and spark while cranking and work from there.

Your battery is toast. It may read 12.6volts but does not store the power it needs start the car. Get a new battery.

Seems to be having problems with the alternator. Alternator itself can be bad, but also the voltage regulator, which sits inside the PCM (powertrain control module).
Don´t continue using with battery voltage around the 10V, because it will ruin your battery as well. Completely charge the battery with an external battery charger and let the alternator be checked out first.

First thing to do is check for errors in the engine system. After that maybe i can help you more.

hi...

this is due to battery problem.
the horn can work even in low voltage but for starting you require more voltage.may be when recharged your battery it has not been fully charged so try recharging it fully or replace it with new battery and check it wil start.

please rate me weather the information which i provided was usefukll to you by clicking on the thumbs present on the end of your page.thank you

You must recharge the battery fully then check the charging system. Spec is 13.5-14.5 volts at 10 amps.
