A faulty fuel pump relay can cause engine stalling and difficulty starting the car. The fuel pump relay plays an integral role in getting fuel to the engine for combustion. When the fuel pump relay isn't working, the fuel pump cannot either. A failed fuel pump relay will leave you without a working fuel pump, fuel cannot reach the engine for combustion.

What You'll Learn
Engine stalls and refuses to restart
If your engine stalls and refuses to restart, it could be due to a faulty fuel pump relay. The fuel pump relay plays an integral role in getting fuel to your engine for combustion. Powered by the ignition and/or powertrain control module (PCM), the fuel pump relay's main function is to provide the fuel pump with enough power. When the fuel pump relay isn't working, then the fuel pump cannot either.
If you're lucky and your car restarts after a short while, your fuel pump relay is faulty, which requires immediate inspection. The fuel relay may be the culprit if the car suddenly seems to lose power while driving, or slowing down with no apparent reason. This does not always mean the car will stall. Sometimes the vehicle will go on running like normal for some time. However, once you experience a sudden loss of power while driving, an inspection and repair are highly recommended.
If your engine stalls and refuses to restart, you’re having a completely failed fuel pump relay and must have it replaced. If you begin noticing any odd changes in your car’s behavior, it is important to follow-up with an automotive specialist right away. Here are the most common signs of fuel pump relay failure that you should be aware of:
- The fuel pump relay may seize to function gradually or all at once.
- The fuel pump relay begins to falter, its ability to power the fuel pump dampens, which can lead to engine stalling.
- The fuel pump relay will leave you without a working fuel pump, fuel cannot reach the engine for combustion.
- The fuel pump relay will make the car die.
When your car begins acting oddly, such as not starting smoothly or occasionally stalling, the problem could be related to a number of different issues—one of which is a bad fuel pump relay.
Since a faulty fuel pump relay will leave you without a working fuel pump, fuel cannot reach the engine for combustion. Trying to turn your engine when the fuel pump isn’t able to perform will prove to be difficult, and often impossible. Issues starting your car can be attributed to a number of different problems with other engine components, so it’s best to have it evaluated and diagnosed by a professional as soon as possible to rule-out other serious causes first.

Fuel pump dampens and can't power
The fuel pump relay plays an integral role in getting fuel to your engine for combustion. Powered by the ignition and/or powertrain control module (PCM), the fuel pump relay's main function is to provide the fuel pump with enough power. When the fuel pump relay isn't working, then the fuel pump cannot either.
The fuel pump relay may seize to function gradually or all at once. If the relay fails slowly, then you might notice engine performance symptoms over time. For instance, as the fuel pump relay begins to falter, its ability to power the fuel pump dampens, which can lead to engine stalling when the engine cannnot start.

Depressurizes the fuel line
If you have a faulty fuel pump relay, it will depressurize the fuel line and no fuel will be delivered to the engine. This will make it difficult, and often impossible, to turn the engine.

Engine stalling when the engine can't turn
If your car stalls and refuses to restart, you're likely dealing with a completely failed fuel pump relay that needs to be replaced. If you're lucky and your car restarts after a short while, your fuel pump relay is faulty, which requires immediate inspection.

If you begin noticing any odd changes in your car’s behavior, it is important to follow-up with an automotive specialist right away. Here are the most common signs of fuel pump relay failure that you should be aware of:
- The car still runs without the fuel pump relay
- The car suddenly seems to lose power while driving, or slowing down with no apparent reason
- The fuel pump relay begins to falter, its ability to power the fuel pump dampens, which can lead to engine stalling when the engine can't turn
- The car stalls and refuses to restart
A stall is the slowing or stopping of a process, and, in the case of an engine, refers to a sudden stopping of the engine turning, usually brought about accidentally. It is commonly applied to the phenomenon whereby an engine abruptly ceases operating and stops turning. It might be due to not getting enough air, energy, fuel, or electric spark, fuel starvation, a mechanical failure, or in response to a sudden increase in engine load. This increase in engine load is common in vehicles with a manual transmission when the clutch is released too suddenly.
If your car stalled out while driving, it might be due to an insufficient amount of power. Your engine needs electricity to run. Thankfully, this is where the ignition system comes in. Once you put the key in and turn it. The battery sends a low amount of electricity to the spark plugs. Which ignites the air/fuel mixture in the combustion chambers, causing a controlled explosion that moves the pistons. Once these are in motion, the alternator kicks in to keep things going. Without a sufficient amount of power, your car can’t power the vital components that keep it running.
