Car Struggles To Start But Runs Fine, What To Do?

Here you are with a trunk full of goods in the middle of a parking lot. Nothing happens when you turn your key. Why in the world is your car struggles to start but runs fine? What do I do next?

This article will assist you in determining the cause of the problem and what you can do to remedy it if your automobile has difficulties starting but otherwise functions normally.

Why Does Your Automobile Have Trouble Starting Yet Run Fine?

Your car might start slowly but otherwise function normally for a variety of reasons. Weather conditions, battery health, wiring problems, starter motor troubles, and fuel-pump issues are just a few examples of possible causes. Check out our guide here if your automobile won’t even try to start. Let’s get started by looking at a few of the typical reasons for a delayed start.

1. System Of Electricity

Your automobile probably has a small electrical system defect if it struggles to start but otherwise works OK. Of course, there are a lot of additional options you should think about as well. However, for the majority of drivers, an electrical inspection will generally resolve this issue.

Keep in mind that it’s not always about the battery. The starter motor, the key, the alternator, and miles of wiring are a few additional notable components of the electrical system.

2. Difficulties With The Starter Motor And Starter Relay

When you turn the ignition on, if you hear a sequence of clicks before the engine starts, your starter relay or the starter motor may be worn out. Over time, the electrical contacts that power your starter motor may deteriorate and supply less and less power to it.

When there is less power, the starter motor spins more slowly, making it difficult to start your car.

If you don’t have this fixed right away, it could cost a lot of money to fix your starter motor.


3. Dying Or Dead Battery

An old or dead battery is one of the usual culprits. Battery power is required for the starter motor to start. In addition, a number of the components depend on batteries to function.

Your automobile will either not start at all or start slowly if your battery isn’t sufficiently charged.
Troubleshooting is simple for batteries that are entirely dead. If your electric key fob isn’t working, it may be because your battery has to be replaced.

4. Fuel Problems

A clog or leak in your fuel lines is another potential reason for a delayed start. Fuel lines carry fuel from the tank to the engine; any obstruction or volume loss due to a leak might cause the pressure to be lower than what is required to drive the engine. While it’s not unusual for a blockage in a fuel line to cause your car to start slowly before running normally again, a pattern of slow starts could indicate something more serious.

5. Spark Plugs Need To Be Replaced

Did you know that every 100,000 miles, spark plugs need to be replaced? That’s roughly the same amount of miles needed to turn your American-made vehicle into a junkyard. We laugh and laugh.

Replace your spark plugs immediately if you want to start your car. These tiny plugs, as we just explained, create a spark that ignites the crucial fuel-air mixture that we keep mentioning. An outdated spark plug won’t provide the same spark as it once did. similar to a former NFL player. Plugs can be removed and replaced with great ease, so this is not a big concern.

What To Do When Car Struggles To Start But Runs Fine?

There could be a lot of issues with your car if it starts slowly. Be aware that troubleshooting will take some time. Determine whether the issue just arises during hot or cold conditions, or if it does so at all times. This will assist in focusing your search.

1. Examine And Maintain Your Sensors

If temperature and airflow sensors are allowed to accumulate dirt over time, they may start to provide inaccurate results. It is easy to resolve this. The hardest step might be finding the sensors, but you should be able to do that with the aid of your vehicle’s manual.

2. Look Into Your Filters

Filters that are blocked are one of the most common causes of a slow start. This might be the oil or air filter. Both of these require routine maintenance or replacement. If you don’t, your automobile may struggle to do the necessary tasks, which would explain why it starts slowly. This is a signal that negative things will start to happen if these filters continue to be unclean or blocked.

3. Check The Fuel Pump

Consider testing your fuel pump after checking your wiring and hoses for damage or leakage. To accomplish this, insert the key into the ignition and turn the car “on,” but not so that the engine starts. Switch it off. Repeat this process three times, and on the third time, fully turn on the automobile so that the engine will start. You’ve currently found a solution if it boots up in three seconds or less. In this instance, you need to replace a gasoline pump that is weak.

In addition, if your fuel pump is poor and it is extremely cold outside, your automobile may entirely fail to start the first or second time you try (below an eighth of a tank.) In this instance, adding fuel not only makes the car start “normally” once again but also identifies the source of your troubles.
