Car stopped, won't start, the only electrical item functioning is the Radio,no lights,all electrical functions dead, starter does not even turn, battery check okay

Sounds like a flat battery. Just enough to power your lights but not enough to power the starter motor. Try recharging the battery.and check battery connections are good.

Even though all your other electrical bits are working it could be that your battery doesn't have enough juice to crank the engine. It doesn't take much power to run the radio, lights, etc, but cranking the engine requires the battery to have a very strong charge. If your battery is more than 5 years old, that's very likely the issue. I'd start there. Also, be sure to check the battery terminals and ground for corrosion and clean if necessary. If replacing the battery doesn't solve the problem it could be the starter solenoid or a loose electrical connection somewhere.

turn on headlights and try to start.. if the lights go dead check the battery(and charge) sounds like its dead already..

Is the battery at 12.6 volts,old or dead?

Cables loose?

Starter Solenoid bad or starter bad

check at the starter for a fuseable link wire as well as at your fuse panel for a possible blown fuse or a bad relay

SOUNDS TO ME LIKE FAULTY ALTERNATER AS WHEN ENGINE IS RUNNING ALTERNATER PRODUCES THE POWER NOT THE BATTERY

did you manage to fix this problem as i'm having the same problems. the car had a flat battery so tried jump starting it but no luck, replaced battery but can only get headlights/windscreen wipers/passenger window and hazards to work. car won't start and alot of the interior controls are dead, i've checked fuses (replaced 2)

What you state is true invest in a new electrical ignition switch that runs off the key cylinder to run power to the starters solenoid. When they go bad the car is totally dead sometimes such as yours. Some will go bad to the starter although other functions may work such as the radio, heater fan, and so on. If your headlights and brake lights work the switch is what you need for the ignition

Do the lights and radio still work while trying to start the car? If not, the battery is shot. If so, then either the starter relay, starter soleniod, or starter motor is defective.

you are right, some Honda's have a radio code, most of the time on the radio chassis itself, but like my sisters she had to gone online and give them her VIN and they sent her the code
