Troubleshooting a 12V Battery That Won’t Start: What to Do When Your Vehicle Won’t Start
If your vehicle won’t start, it can be a frustrating experience. Fortunately, there are a few steps you can take to troubleshoot the issue and get your vehicle running again. First, check the battery. Make sure the terminals are clean and free of corrosion. If they are corroded, clean them with a wire brush and baking soda. If the terminals are clean, check the voltage of the battery with a multimeter. If the voltage is below 12V, the battery may need to be replaced. Next, check the starter. Make sure the starter is receiving power from the battery. If it is not, check the starter relay and the starter solenoid. If these components are working properly, the starter may need to be replaced.
If the starter is receiving power, check the spark plugs. Make sure the spark plugs are clean and free of debris. If they are dirty, replace them. If the spark plugs are clean, check the spark plug wires. Make sure the wires are connected properly and that there are no breaks in the insulation.
Finally, check the fuel system. Make sure the fuel filter is clean and that the fuel pump is working properly. If the fuel filter is clogged or the fuel pump is not working, the fuel system may need to be serviced.
