Several possibilities come to mind with that description: You COULD have a bad solenoid or starter, you COULD have a bad keyswitch, you COULD have a bad battery connection that needs cleaning. I'm certain there are numerous other possibilities that could account for what you describe, these are just the first things I would look at. If you have any other information on the subject post another question and I'll put this on a watchlist.
More than likely you have corrosion at the terminals. Clean the battery terminals and then recharge the battery and see what happens.
it is illegal and shame on you for doing this to someone apoligize to them today immidiatly
It could be a bad battery, or connection. A bad starter and or solenoid could be the problem, along with an ignition switch to name a few.
You could accidentally short out the power wire to the radio and blow a fuse. But you really do not have to disconnect the battery terminal. Just remove the fuse for the radio circuit and you will be fine.
you either overlooked a hot lead that needs to be reconnected at the battery, or you grounded a hot wire and blew a fuse or fusible link wire
Low battery voltage? poor battery connections?
once a battery is connected even if the key is not in the ignition, there is always power at certain points in your car. Connecting a battery backwards will not start your car, but it can and will fry the wires to your starter.
This happens a lot. We finally figured out to disconnect the battery and wait 20-30 seconds. I actually heat a "click" in the steering wheel/ignition area in the car and the key works fine.
Possibly the ignition switch is defective.
If you don't disconnect the battery when installing gauges, it is possible to create a short circuit and blow a fuse. Some gauges have power present even when the ignition switch is turned off.
First guess; the battery is dead. Second; a break in the ignition switch wiring. NOTHING happens? No noise, no clicks, NOTHING? Check to see if the ceiling light comes on when you open the door.
your battery is probably dead...., if when you turn the key and nothing happens at all...your battery is probably dead... Solution: Well, it turns out it was my ignition switch. That was my first guess. Im glad i went with it.
