Car Mechanic Simulator 2021: Engine Won’t Start

Troubleshooting a Non-Starting Engine

When your car’s engine won’t start, it can be a frustrating experience. There are a number of potential causes for this problem, and troubleshooting can be a challenge. However, by following some simple steps, you can often identify the issue and get your car back on the road.

Step 1: Check the Battery

The battery is responsible for providing the power needed to start the engine. If the battery is dead or weak, it will not be able to provide enough power to the starter motor to turn over the engine.

To check the battery, you can use a multimeter to measure the voltage. A fully charged battery should have a voltage of around 12.6 volts. If the voltage is below 12 volts, the battery may be weak or dead and will need to be replaced.

You can also check the battery by trying to start the car. If the engine cranks slowly or not at all, the battery may be dead.

Step 2: Check the Starter Motor

The starter motor is responsible for turning over the engine. If the starter motor is not working properly, it will not be able to engage the flywheel and start the engine.

To check the starter motor, you can try to tap it with a hammer or wrench. If the starter motor is working properly, it should start turning over the engine.

You can also check the starter motor by listening for a clicking sound when you turn the key to the start position. If you hear a clicking sound, it means that the starter motor is engaging the flywheel but is not able to turn over the engine. This could be due to a problem with the starter motor itself, the electrical system, or the engine.

Step 3: Check the Fuel System

The fuel system is responsible for delivering fuel to the engine. If there is a problem with the fuel system, the engine will not be able to get the fuel it needs to start.

To check the fuel system, you can start by checking the fuel level. If the fuel tank is empty, you will need to fill it up.

You can also check the fuel pump by listening for a humming sound when you turn the key to the on position. If you do not hear a humming sound, the fuel pump may not be working properly and will need to be replaced.

You can also check the fuel filter by removing it and inspecting it for dirt or debris. If the fuel filter is dirty or clogged, it will need to be replaced.

Step 4: Check the Ignition System

The ignition system is responsible for providing the spark needed to ignite the fuel in the engine. If there is a problem with the ignition system, the engine will not be able to start.

To check the ignition system, you can start by checking the spark plugs. The spark plugs should be clean and free of any deposits. If the spark plugs are dirty or damaged, they will need to be replaced.

You can also check the ignition coil by testing it with a multimeter. The ignition coil should have a resistance of around 10,000 ohms. If the ignition coil is not working properly, it will need to be replaced.

You can also check the distributor cap and rotor by inspecting them for dirt or damage. If the distributor cap or rotor is damaged, it will need to be replaced.

Step 5: Check the Timing Belt or Chain

The timing belt or chain is responsible for synchronizing the timing of the engine’s valves and pistons. If the timing belt or chain is stretched or damaged, it can cause the engine to run poorly or not at all.

To check the timing belt or chain, you will need to remove the timing belt or chain cover. Once the timing belt or chain is exposed, you can inspect it for any signs of wear or damage. If the timing belt or chain is stretched or damaged, it will need to be replaced.

Conclusion

If your car’s engine won’t start, there are a number of potential causes. By following the steps outlined in this article, you can often identify the issue and get your car back on the road.

If you are not able to identify the problem yourself, you may need to take your car to a mechanic for further diagnosis.
