My car will not start and there is no power to the car even after replacing the battery. What else could it be?

check for battery voltage at the large terminal on the starter. THere should be power at all times.

Have a helper turn the key to the crank position while you check for power on the smaller wire at the starter. There should be power anytime the key is in the crank position.

If there is power at both terminals than the starter is bad. If there is no power at the large wire check your battery connection. If there is no power at the the small wire you will need to trace it back to its origin.

Replace the Battery first

Clean cable connections. Did you use a memory saver when you replaced the battery?

Do the headlights dim when the key is turned to the start position?

Won't CRANK,right?

There is a reset procedure after disconnecting the battery

check the alternator and check for a short or ground a wire may be touching the frame you may want to check the engine computer module

Can you describe a bit more about what you tried? Have you checked the strength of the battery? Even if the battery powers most of the accessories it may not have enough power to crank the engine. Will it start if you try to jump it?

check the battery cable for a good connection then make sure its in park move the gear shifter around and place back in park. check the head lights for full power. last thing is jump it with cables to make sure the battery is strong.

The reason your battery only reads 10 volts is because a battery is made up of 6 individual cells. One of the cells is bad. So even by jump starting your vehicle with another car you will still only get 10volts from your batter plus a small 12 volt boost from the other car but only as much amperage as the battery cables will carry. You may also find that the starter is dragging a bit. By replacing your battery you will get a lot more starting power.

The blinking "S" means your Transmission Control Module is faulty. Replace.

could be a bad ground cable .replace battery cables if they havent been change in a while.if it still dont crank .remove starter have it tested.at advance auto parts and auto zone. if starter good.replace starter solenoid or relay.
