Why wont my engine crank or start?
If your engine won't crank or start, it could be due to a variety of issues. The most common causes include a dead battery, a problem with the starter motor, or an issue with the fuel system. Let's explore these potential problems in more detail.
Dead Battery
A dead or weak battery is one of the most common reasons an engine won't crank or start. The battery provides the electrical power needed to turn over the engine and start the ignition. If the battery is not holding a charge, the starter motor won't have enough power to crank the engine. You can try jump-starting the vehicle or replacing the battery to see if that resolves the issue.
Starter Motor Problems
The starter motor is responsible for turning the engine over when you turn the key or push the start button. If the starter is faulty, it won't be able to crank the engine, preventing the vehicle from starting. Signs of a bad starter include a clicking noise when you try to start the car or the engine not turning over at all. You may need to have the starter motor tested or replaced.
Fuel System Issues
Problems with the fuel system can also prevent the engine from starting. This could be due to a clogged fuel filter, a faulty fuel pump, or an issue with the fuel injectors. If the engine is not getting the necessary fuel, it won't be able to start. You may need to inspect the fuel system and make any necessary repairs.
Other Potential Causes
- Loose or corroded battery connections
- Faulty ignition switch or wiring
- Mechanical issues with the engine, such as a seized or damaged component
- Problems with the engine's computer or sensors
If you've checked the battery, starter, and fuel system and the engine still won't crank or start, it's best to have a professional mechanic diagnose the issue further. They can use diagnostic tools to identify the root cause and make the necessary repairs to get your vehicle running again.

How to know if an engine is seized?
The best way to tell whether an engine is seized is to try to turn it over with a breaker bar. First, remove the engine's drive belt. Then, place the breaker bar on the crankshaft pulley bolt and try to turn the pulley in the normal direction of engine rotation (usually clockwise).

Bad alternator
Connected to the battery is the alternator, which works to generate power for your vehicle's electrical components. When you have a brand-new battery but still can't start the car, the alternator might be the issue. Cold and damp climates may increase wear on an alternator, causing it to fail.
