check battery new doesnt mean free from defects --try reprogramming --try other key fob--test ignition system--

check for governor control lever, module, spring broken etc, any thing that is connected to the carby butterfly that is loose or not working as it should

it wont crank, no A/t car starts unless cranked first. (a key point)

fix head lights first. this is a feature in all cars.

that is SIMPLE and HOT all the time

they must work at all times and is the top way to diagnose

electric problems



you have a dead battery,.

only why remains.

i bet it cranks jumper cable started, call AAA or buy some cables.

or swap in a charged battery , or heck charge yours, buy a charger.

check fuses.

check battery lugs for green death?

check battery voltage. at 12.6vdc, if not charge the battery

if the battery continues to disgharge.

that is called phantom drains, or bad battery .

or the alternators is bad.(system)

once started the battery volts must be 13.3.to 15v, if not the charge system is bad ,(fuses, belts slipping and lots more possibles)

I'm not a car mechanic, but, it sounds like you might want to check the fuse to the ignition switch, and, if that fails, it might be a problem with the Start Safety Switch on the transmission. Good luck.

you may need to have your immobilizer reset at the honda dealership.

Does the new battery turn the motor over? Sounds like bad/dirty cable connections...

what are the codes coming up

did the security system kick in is the light flashing with the key on it?try another key may need to be reprogrammed

you will need to try a new battery, unfortunatly sometimes jumping of a larger battery can spike the regulator, so when the new battery is fitted put a mulimeter across the battery, should read just over 12v engine stopped and rise to 13.5-14v with the engine running.
