7 Reasons Your truck Can’t Start

Have you ever found yourself in a situation where the truck can’t start? You have had a long day and preparing for a tougher one the next day. You wake up slightly early to go for a trip, but you realize the engine coughs and sputter instead of starting. 

There are several reasons why your truck can’t start. You will be compelled to turn to a professional mechanic, before taking such a decision. There are several things you can check on your own. After reading this guide, you will understand the possible reasons why your truck will not start.

Why Your Truck Can’t Start

  1. Dead Battery

Several reasons can lead to the death of your battery and this can lead to a situation where the truck can’t start. It may be due to loose wires or even evaporation that leads to insufficient conductivity, or you forgot to turn off your light the previous day.

To solve this, you can jump-start your truck. If the jump starting is unsuccessful, your battery could die, and you should replace it. 

2. Alternator Issues

When your alternator is faulty, the battery will not be able to receive an adequate charge. If you feel your alternator is faulty, check if there is a worn-out drive belt. A check light will appear on your dashboard when the alternator or the belt is faulty. 

Sometimes the check light might not appear. In such a situation, check if the instrumental panel displays 14 volts. When you experience a weak cranking, it indicates that your battery is not charging.

3. Faulty Spark Plugs

Faulty spark plugs are not a common issue nowadays, but if it occurs, it can be challenging to start your truck. When your spark plugs become faulty, forming sparks in the combustion chamber will be challenging. As a result, you will experience starting issues. 

4. Clogged Air Filter

Air filters trap dirt from the air and keep your engine clean. As they trap the dirt and other particles, they become clogged, preventing air from reaching the combustion chamber. Air is an essential ingredient for combustion. If it is not present, your truck will experience starting issues. 

5. Faulty Fuel Filters

The fuel filter is another part of your truck that functions similarly to the air filter and this can lead to a situation where the truck can’t start. The engine combustion chamber is sensitive, and it should receive clean fuel. When the filter is clogged or faulty, the combustion chamber will not receive adequate fuel, and this can lead to starting problems. 

6. Faulty Fuel Pump

A fuel pump generates the pressure to move fuel from the tank to the combustion chamber. When your fuel pump is faulty, the combustion chamber will not receive adequate fuel, which can lead to starting issues. To check if your fuel pump is faulty, turn on the engine and check if it is running. 

7. Faulty Starter

The starter is the electrical component of your truck responsible for starting your truck. When you turn the engine on, the starter receives power from the battery, which later transmits this power to the spark plugs through the coils. If faulty, it will not transmit power to the spark plugs, and you will experience starting issues.


Truck starting issues result from various reasons. When you experience it, consider checking your fuel gauge. The above are the common reasons why a truck is not able to start. If you experience any of them, take your truck to a professional to check and fix it.
