One of the most frustrating things that can happen to a car owner is when their car engine won’t start. There are many reasons why a car may not start, but one of the most common is a starting system fault. This can be caused by a number of different things, including a dead battery, a faulty starter motor, or a bad alternator. In this article, we will discuss how to fix a starting system fault and get your car back on the road.
Step 1: Check the Battery
Source: bing.comHow to Fix Starting System Fault The first thing you should do when you experience a starting system fault is to check the battery. A dead or weak battery can cause your car engine not to start. To check the battery, turn on your headlights. If they are dim or don’t turn on at all, your battery may be dead. You can also use a multimeter to test the voltage of the battery. If the voltage is below 12 volts, you may need to replace the battery.
Step 2: Check the Starter Motor

If the starter motor is faulty, the engine won’t turn over. To check the starter motor, turn the key to the “on” position and listen for a clicking or grinding noise. If you hear a clicking noise, the starter solenoid may be faulty. If you hear a grinding noise, the starter motor may be worn out and need to be replaced.
Step 3: Check the Alternator

If the alternator is faulty, the battery may not be receiving enough charge, which can cause it to die. To check the alternator, start the car and use a multimeter to test the voltage at the battery. If the voltage is below 13 volts, the alternator may be faulty and need to be replaced.
Step 4: Check the Ignition Switch

The ignition switch is responsible for sending power to the starter motor when the key is turned. If the ignition switch is faulty, the starter motor may not receive the signal to turn over. To check the ignition switch, use a multimeter to test the voltage at the starter motor while turning the key. If there is no voltage, the ignition switch may be faulty and need to be replaced.
Step 5: Check the Wiring

To check the wiring, inspect all of the connections and look for any signs of damage or corrosion. If you find a damaged or corroded wire, replace it.
Step 6: Check the Fuel System

A clogged fuel filter or a faulty fuel pump can cause your car engine not to start. To check the fuel system, inspect the fuel filter and look for any signs of clogging. You can also test the fuel pressure using a fuel pressure gauge. If the fuel pressure is low, the fuel pump may be faulty and need to be replaced.
Conclusion
A starting system fault can be caused by a number of different things, including a dead battery, a faulty starter motor, a bad alternator, a faulty ignition switch, loose or corroded wiring, or a clogged fuel filter. By following the above steps, you can diagnose and fix the problem and get your car back on the road.
