Why will a 1997 Jeep Wrangler turn over but not start with a new battery if it worked before the battery went dead?

Did you hook the battery up backwards before realizing the wrong polarity? Kiss the PCM goodbye.

Did you take the nice thin plastic cap off the negative pole that is placed on some batteries?. It's easy to miss if you are not looking for it and paying close attention. It's also possible that the new batter was DOA (Dead on Arrival), it can happen.

The engine needs good battery power, fuel and spark to start and run. You are missing one of those.

The same way you started it before replacing the battery.

you have to reset set the throttle woth scan tool or also known as adaptive relearn

Was it running before the old battery went south? Did you have a check engine light before you replace the battery?

disconnect battery, then turn everything you can think of on, then after 20 mins reconnect battery making sure a firm connection to minimise sparks. start car.

The fuel pump is starting to go bad. You might verify that battery again too. I know places like Auto Zone will do a free battery test for you. From my research you need at least 500 amps to 600 amps depending on your model to get a smooth start from a Jeep Wrangler. The last battery I had on my 1998 Wrangler Sport (4.0L I-6) would give a few "wrr, wrr, wrrs" from its 700 amp battery before it would finally crank. Auto Zone ran the quick test which took like 15 seconds and the battery showed to only be producing 302 amps. I replaced it with a new 700 amp battery and it cranks like a champ every time.

Yes, the battery may be defective is you cannot jump start the car. The battery may also be so low as to need to be charged some before you attempt to start the car. Put a charger on the battery and see if it will accept a charge.

to provide current to start vehicle and supply modules with voltage before start up

In most cases a new battery will be charged enough to start the vehicle

did you unhook the battery before replacing the alternator

It's gotta be the battery/electrical. Prob a corrosion in the battery line that shocked the electrical system get it towed to a dealer and tell them your story.

I once replaced the distributor and worked to clean the battery posts and all sorts of stuff before finally realizing it was a blown ignition fuse. Van would turn over but not start. replaced the 35 cent fuse and I was on my way..

Maybe your new battery is dead or needs a charge before using.

No, you do not have to disconnect the battery. Just do not start the engine with the charger connected unless the charger is built for starting purposes.

There are several different things that could be causing your car not to start. You may be out of gas, your starter might be bad, or your battery could be dead.


Correct, a car will not start with a disconnected battery

YesFirst if the starter is bad the car will not start, if it will not start it can not charge the battery.If the starter will not work it can mean there is an electrical problem that will also prevent the alternator from charging the batteryThe starter itself CAN NOT CAUSE CHARGING PROBLEMS!The extra load on the battery can ruin the battery and that can ruin the alternator. But before that NO.
