Q: I have a new battery but my car won't start

asked by on

Put new battery in and still won't start

My car has 200000 miles.
My car has a manual transmission.

The solution will depend on the symptom you are observing as you try to start the car. I recommend a no-start diagnostic which will identify the root cause. There are a lot of possibilities but if the engine does turn over and cranks, but the car won’t start and run, the following are some areas that a mechanic would consider: fuel pump, spark plugs, timing belt, ignition coil, cam or crank sensor, and others. If in your situation "nothing" at all happens when you turn the key, that is the starter motor itself won’t turn, you could have problems with: battery connections, fuses, the starter motor and circuit, contacts in the ignition switch or other wiring faults.
