An engine that cranks, but doesn’t start, may have battery issues. There’s a possibility that the battery doesn’t have enough power, either because it’s been drained or because it’s nearing the end of its lifespan. There could also be corrosion on the battery terminals.
If your vehicle won’t start, it’s usually caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter. It can be hard to determine if you’re dealing with a battery or an alternator problem.
If the engine holds compression well, and the fuel system is working correctly, but it still won’t start, that tells us that your car’s spark plugs may not be working. The spark plugs ignite the air/fuel mixture inside the engine’s cylinders. It’s the resulting explosion that actually powers your car.
Why does my Subaru click but won’t start?
It might be a faulty starter.
One of the symptoms of a bad starter is a single clicking noise when you turn the key or push the start button. Tapping the starter can sometimes get it going again, but no guarantees. Most likely, you’ll need to get your starter repaired or replaced.

How do you tell if it’s your battery or alternator?

What does a bad alternator sound like when starting?
It requires a good deal of energy to crank the car’s motor, and if a battery is not replenishing its power properly due to a faulty alternator, it will become drained and ineffective. You will hear a clicking noise while attempting to start the car, and the engine will have difficulty turning over.
If your alternator is dead, the car might start but will be running solely on the battery. Can you jumpstart a car with a bad alternator? It is possible in some cases to jumpstart a vehicle that has a faulty alternator, as long as the battery has enough of a charge to keep running.

What happens when an alternator starts to go bad?
A bad alternator will result in a discharged (dead) battery and cause a vehicle to not start or run. Alternators are designed to maintain a battery’s charge, not to recharge a dead battery. Your alternator’s job is to maintain a consistent charge on your battery. Draining your car’s battery is not advised.
