It’s not uncommon for drivers to find themselves stranded on the side of the road, unable to start their vehicle. Running out of fuel, having a defective fuel pump, having a dead car battery, etc. are all possible causes.
Whether or whether your fuel pump is to blame for your vehicle’s malfunctions will be explained in this post, along with the necessary measures to take to fix the problem.
What Is A Fuel Pump?
A fuel pump is a part of a car’s internal combustion engine that moves fuel from the tank to the carburetor.
Fuel pumps are powered either directly or indirectly by the engine’s crankshaft. This is a prevalent problem in automobiles with electric pumps, because fluid is required for the system to function.
At least 17 pounds per square inch (psi) of pressure must be maintained in order for a conventional vehicle gasoline pump to function properly, and this is between 12 and 15 pounds per square inch (psi).
A poor seal on the fuel pump can allow trapped gas to seep out, or the fuel pump itself can malfunction and allow air into the system. When a vehicle’s fuel pump malfunctions or fails, it can result in everything from an engine stall to the complete breakdown of the entire system.
In many cases, fuel pumps cannot be repaired, so it is imperative that they be replaced as soon as possible.

Yes, if your car’s gasoline pump fails, it may not be able to start. Basically, the car will not start if the fuel pump fully fails and is unable to supply enough fuel to the engine to run.
Can Car Refuse To Start After Replacing Fuel Pump?
After replacing the gasoline pump, it is not uncommon for a vehicle to refuse to start. A malfunctioning fuel pump module or worn-out electrical connections between the wiring harness and the fuel pump relay can cause this.
Alternatively, the fuel pump installed in your vehicle may be defective, or the manufacturer may have made a mistake when it was manufactured.
It’s also important to keep in mind that the fact that your automobile won’t start after you replace the fuel pump could simply be a coincidence. Cars can sometimes fail to start for other reasons, such as:
If your vehicle is old and has not been repaired in a number of years, you should take it to a mechanic right away.
If the vehicle’s engine has any further problems, consult a mechanic right away.
If your car’s battery dies, you’ll need a new one.
Etc.
Is there anything you could have done in this situation?

All of the following should be verified:
Keep an eye on the tank’s gas level (if necessary, add more)
Verify that the issue isn’t only one of a faulty ignition or a faulty connection (try to start the car again)
You should check to see if the relay for the gasoline pump is working.
This means that if all of these things fail, you’ll need further diagnostic and repair, which may possibly require the replacement of the fuel pump.
There is a possibility that an electrical problem in the wiring harness, which houses the relay, could be to blame for this.
It’s more likely, however, that the problem is with the ignition rather than the gasoline pump.
If this is the case, tightening all connections and checking the spark plugs in both cylinders should get your car started again. A new ignition coil may be necessary.
