While a brand new fuel pump should ideally serve to inject more power into the vehicle, there could be several reasons why this won't happen immediately. Knowing these problems can help to diagnose the issue correctly.
Start out by verifying you installed everything correctly. Most fuel pump failures, approximately 70%, result because of an improper installation such as misaligned connections or incorrect wiring. This poor engagement, which will not even happen if the pump is not fastened in securely resulting in another fucking pain for the owner.
Other The electrical supply is the first to see if it works correctly. Fuel pump require a steady voltage supply — generally around 12 volts. A weak battery or a blown fuse can protect the pump from running. Since they are sometimes so forgotten, this should be an essential part to check first.
Furthermore, one of the parts that is essential for pump operation is the fuel pump relay. This relay failure can then disrupt the power supply to the fuel pump and cause a lack of function. This is a common problem that may be solved by performing regular inspection of relays.
And then look at fuel quality. Incorrect contaminants in oil can block the pump, this leads to failure of the pump over a period. This represents 30% of the fuel related claims reported. Quality fuel should always be used, and you may want to consider running a fuel additive through the system.
Unless it is a installation error, electrical issue, or fuel quality its probably an internal problem. Even new pumps can have mechanical failures, including a damaged impeller. Most manufacturers warranty this issue so it can be replace free of charge.
Automotive expert John Paul often says — "It is frequently not the part, but how it integrates with the rest of the system that makes it work or fail. This only serves to highlight the need to look at all aspects of getting fuel delivered.
So in short, if you are struggling with a new fuel pump that stopped working always double check the installation, electrical supply and what quality fuel your working with. When they are in line and the provide adequate power, then it might be worth going to a professional for more diagnostic help.
