Blocking of the fuel pump is a common problem that you can face in any vehicle. The same is true for Chrysler 300 as well. However, if you reset the fuel pump of your Chrysler 300, it is easy to increase the efficiency of the fuel pump once again.
How do I reset my fuel pump in Chrysler 300?
Method 1: Fix or replace the relay:
In most cases, the issue is not with the fuel pump but rather with the fuel pump relay. That is why; you have to work towards fixing it. Fixing it will ensure that all the problems you face because of the fuel pump or the relay will be sorted out.
Unfortunately, you will have to contact a mechanic to fix the fuel pump relay. It is difficult to do that yourself since it is one of the core systems of your car.
Method 2: Reset the airbag control module:
Resetting the airbag control module will reset the circuit of the pool pump as well. That is why this is the only way in which you can reset it.
Step one: look at the inertial trigger:
The inertial trigger can be behind the glove compartment, behind the driver’s dashboard, or inside the passenger side kick panels. You can refer to the manual of the Chrysler 300 to better understand where it is located.
Step 2: Press the switch:
Once you locate the switch, press it. From the manual, you have to gain knowledge about the color of the switch and after that press it. Doing so will undoubtedly reset the fuel pump and the associated circuit.
In these two simple steps, you can reset the fuel pump circuit.
When should I reset Chrysler 300 fuel pump?.
1. Frequent loss of power:
The fuel pump’s job is to regulate the amount of fuel provided to the engine. If the fuel pump or the associated circuitry is not functioning properly, the amount of fuel will not be consistent with the engine’s requirement. In that case, the combustion process will be hampered.
When it happens, the engine will not be able to generate the required amount of power. It means that you will experience frequent loss of power if the fuel pump has an issue.
The best way is to reset the fuel pump using the two methods above. Once you do so, the regulation of the fuel will be efficient once again, and therefore loss of power will not occur.
2. Engine starting problem:
When the fuel pump or the associated circuitry is not functioning properly, the amount of fuel supplied to the engine may not be enough to start the engine. As you might very well know, the amount of fuel required is much larger during the start-up process. If the fuel supply is hampered at that stage, the engine might not start at all.
Sure enough, after trying out for 5 to 10 minutes, the engine might finally start, but persistent engine starting problems indicate a problem with the fuel pump or the associated circuitry.
3. Pump noise being different:
If you are well versed with the sound of the engine and the combustion process, you can recognize the sound of the fuel pump.
Whenever the fuel pump or the associated circuitry has a problem, the pump noise will be entirely different. In that case, you will notice the different engine noise as well.
Most Chrysler 300 owners will just ignore the noise. However, instead of ignoring it, it is a good idea to work on fixing the problem. You will not have to wait for the fuel pump or the associated circuitry to fail.
4. Overheating of vehicle:
In the absence of an appropriate quantity of fuel, the engine might try hard to produce the required power. It means that the engine will overwork to compensate for the lack of fuel or lack of power.
When the engine is constantly being overworked, it will certainly raise the temperature under the hood. It means that your entire vehicle might overheat as well.
Also, in some extreme circumstances, an improper fuel pump becomes a fire hazard. That is why, if you notice the heating of the vehicle, it is a much better idea to follow the procedures to reset the fuel pump and solve the problem.
5. Reduced fuel efficiency:
You might think that the problem with the fuel pump means that the vehicle will be using less fuel. However, that is not true. The regulation mechanism will not be proper, and therefore sometimes there will be a scarcity of fuel, and sometimes excess fuel might be provided to the engine.
All this will mean that the vehicle’s fuel efficiency goes for a toss. That is why, if you notice a sudden drop in the vehicle’s fuel efficiency, it might indicate a problem with the fuel pump.
What happens after resetting the fuel pump in Chrysler 300?
There are a few changes that you will notice instantly after resetting the fuel pump in case it was suffering from a problem. These include:
- The sound of the engine will be back to normal. This is the most instantaneous difference you will notice.
- Over time, the fuel efficiency of your Chrysler 300 will also go up.
- Additionally, your vehicle’s power will be much more regulated now, and therefore controlling your vehicle becomes easy.
- The overheating problem is likely to be eliminated once you reset the fuel pump.
