Top 5 Reasons Behind No Spark from Distributor

People are highly dependent on their vehicles these days. Whether traveling to vacation, work, or school, vehicles make our lives easier and comfortable.  Many times, cars’ engines fail to start. When a car engine cranks but doesn’t start, then it is highly likely that there is no spark from distributor. When troubleshooting the problem, knowing the exact reason is essential.

No Spark From Distributor: Why Does it Happen?

Many car owners face trouble getting their vehicles’ engines to start. Firstly, it is imperative to confirm that the car engine has no spark. Make sure, to begin with, a fully charged battery before proceeding with testing.

You will be required to disable the fuel system and put a spark plug tester. Eventually, seek the help of a person to crank the engine and look for spark. You can stay updated about the car maintenance tips to improve your car engine functioning.

Once it is crystal clear that the engine has no spark, then the second step is finding the reason. Outlined here are some prominent reasons to help you find the issues.

Crankshaft Position

First thing first, see if there is any broken or loose wire connecting sensors to the power control module. The Crankshaft position sensor can help you find the issue with the crankshaft. This sensor tracks the rotational speed of the crankshaft. If the sensor stops working, it fails to send a signal to ECU.

An Issue with Ignition Module  

When you are unable to start a car, you need to check ignition modules. Transistor helps these solid-state switching devices for controlling current flow and switching on and off with the primary winding of an ignition coil. So, it wouldn’t be wrong to say that they act as mechanical points.

Some external input is required to help ignition modules do the task. Loose, broken, or corroded wires in the ignition module can be a reason behind no spark from distributor. Cleaning oxidized terminals and replacing broken wires is a good decision.

A Problem with Ignition Coil

The ignition coil turns the weak battery power into a powerful spark. Sometimes, a car runs for some time, and then the engine stops working. A faulty ignition coil could be a sign of such a problem in the vehicle. Due to the increase in the temperature of the ignition coil or module, this problem arises. The good news is that it starts working once it is cooled down. An issue with the ignition coil results in the vehicle failing to start.

Cracked Distributor Cap

Checking distributor cap is paramount when a vehicle stalls suddenly and fails to start again, Check whether the inside or outside has some dirt. It ought to be rust or corrosion-free. Besides, consider checking the working of the rotor and cracks on the distributor cap.

Faulty Ignition Switch

Mounted in the engine’s combustion chamber, the ignition switch is the weakest part of a vehicle’s ignition system. There are three positions in the ignition switch, which you will notice after inserting the key. When switching to the “ON” position, dashboard lights bright up. If they fail to light up, it could be a sign of a bad ignition switch.

Final Note

Many people face the problem of getting their car engine start. No spark from distributor can be due to the above reasons. Taking your car to experts is highly recommended because they can diagnose the problem and solve the issue as soon as possible.
