What to do if my car won’t start

Car won’t start?

When your car won’t start, it can be frustrating and inconvenient. Here’s what you can do to troubleshoot and possibly resolve the issue:

Check the battery

Firstly, check if the car won’t start due to a dead battery. Sometimes, the problem is as simple as the battery being drained because lights or accessories were left on. Try jump-starting your car using jumper cables and another vehicle with a charged battery. If this works, let your car run for a while to recharge the battery.

If jump-starting doesn’t work, the issue could be with the battery terminals. Check for corrosion or loose connections. Cleaning the terminals with a wire brush and making sure they are securely connected may solve the problem.

Starter motor

Another common reason a car won’t start is a faulty starter motor. When you turn the key and hear a clicking sound but the engine doesn’t crank, it could indicate a starter motor issue. In this case, tapping the starter motor lightly with a tool like a wrench or hammer while someone tries to start the car might temporarily solve the problem, but it’s best to have a mechanic inspect and possibly replace the starter motor.


Fuel-related issues can also be the reason why your car won’t start. Check if you have enough fuel in the tank. Sometimes, car won’t start because it’s out of fuel or the fuel gauge is faulty. If you suspect a fuel issue, try adding fuel to the tank and see if the car starts.


Additionally, a faulty ignition switch or a blown fuse can be the reason why a car won’t start. Check the fuse box for any blown fuses and replace them if necessary. If the ignition switch is faulty, you may need to have it replaced by a mechanic.

Sometimes, the car won’t start due to problems with the fuel pump or fuel injectors. If you turn the key and the engine cranks but doesn’t start, or if you don’t hear the fuel pump priming when you turn the key to the “on” position, these components may need to be checked and replaced if faulty.

Electronic issues

In some cases, electronic issues with the car’s computer system, such as a malfunctioning sensor or immobiliser, can be the reason why your car won’t start. If you suspect an electronic issue, it’s best to have a mechanic with diagnostic tools check the car’s computer system for error codes.

Why is my car not starting but has power?

If your car has power but isn’t starting, it could be due to several common reasons. One possibility is a problem with the starter motor. When you turn the key, you might hear a clicking sound or nothing at all, which can indicate the starter motor isn’t engaging properly. This could be due to a worn-out starter motor, a faulty starter solenoid, or issues with the electrical connections.

Another potential cause is a weak or drained battery. Even though your car’s electrical systems might still have power, the battery may not have enough charge to crank the engine. This could happen if the battery is old and needs replacing, or if something like lights or accessories were left on and drained the battery overnight.

Additionally, issues with the ignition switch, fuel system, or electronic components could prevent your car from starting. Problems with the ignition switch might prevent the engine from receiving the signal to start. Issues with the fuel system, such as a clogged fuel filter or faulty fuel pump, could prevent fuel from reaching the engine. Electronic problems, like a malfunctioning engine control unit (ECU) or immobiliser, could also interfere with starting the car.

How to tell if it's starter or battery?

If your car won’t start, then determining whether the issue lies with the starter or the battery can be done with a few simple steps. When you turn the key and hear a clicking sound or nothing at all, it often suggests a problem with the starter motor. This component is responsible for cranking the engine to start your car.

On the other hand, if the engine cranks sluggishly or doesn’t crank at all but you have power for lights and accessories, it’s more likely a battery issue. A quick test is to try jump-starting your car. If it starts with a jump, the battery is likely the issue. If jump-starting doesn’t work and you still hear clicking or nothing when turning the key, then the starter motor may need attention.

If you’re unsure or need assistance, our mobile mechanic can diagnose the problem using proper tools to pinpoint whether it’s the battery or starter causing the starting problem.

Why is my car clicking but not starting?

When your car clicks but doesn’t start, it’s often a sign of an issue with the electrical system, typically involving the starter motor or the battery. Here’s a simple explanation:

The clicking sound you hear usually comes from the starter solenoid, which is an electrical switch that sends power to the starter motor. When you turn the key to start your car, the solenoid engages but may not have enough electrical power to fully activate the starter motor. This can happen if the battery is low on charge or if there’s a poor connection between the battery and the starter motor.

Possible reasons for this issue include a weak or old battery that doesn’t have enough power to crank the engine, or corroded or loose battery terminals that prevent sufficient electrical flow. Another potential cause could be a faulty starter motor or solenoid that needs to be replaced.

To troubleshoot, you can try jump-starting your car with jumper cables and another vehicle with a charged battery. If the car starts with a jump, it’s likely the battery that needs attention. If jump-starting doesn’t work and you continue to hear clicking without the engine cranking, then the issue may lie with the starter motor or solenoid.
