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.
If the car makes clicking noises when you’re trying to start it and the battery isn’t at fault, a faulty starter motor might be the culprit. Plenty of other parts can fail: the fuel filter, fuel pump, timing belt, spark plug, ignition switch, or cables to name a few.
