There are a few reasons why your engine will overheat even though the cooling system is okay. You might have a cracked exhaust manifold gasket, a cracked engine block, or a malfunctioning catalytic converter. Another thing that will overheat the engine is a faulty fuel pump. If the fuel pump does not draw enough fuel out of the tank to keep its motor cool, Mechanic One Auto Repair & European Auto Repair advises that your engine will overheat. Here are other signs that your fuel pump is going out.
A Reduction in Fuel Pressure
The fuel pump generates fuel pressure so any malfunction will cause a reduction in the fuel pressure. Your engine cannot run efficiently without the proper fuel pressure. The fuel pressure can be tested to see if it is within the manufacturer’s recommended range. If it isn’t, this is a sign that your fuel pump is going bad and needs to be replaced.
Difficulty Starting the Engine
If you have over 100,000 miles on your odometer and you are having difficulties starting your automobile, it’s possible that there isn’t enough fuel in the combustion chamber. This can be caused by a malfunctioning fuel pump. If the fuel pump is not working at all, you may not be able to get your vehicle started because there will be no fuel in the engine.
Engine Stress Power Loss
Let’s assume for the moment that you have a pickup truck with a fully loaded bed. You’ve noticed that the engine has lost power since you loaded the bed. This is an example of engine stress. The engine needs additional fuel to maintain power when a vehicle is loaded, when you are towing a trailer, and when you are driving up hills. Power loss indicates that the fuel pump is not pushing enough gasoline or diesel fuel through to the engine to accommodate the additional stress.
High-Speed Engine Sputtering
Another thing that will happen with the faulty fuel pump is your engine will sputter at high speeds while you are driving. The faster you go the more fuel you need to maintain engine power. If there isn’t enough fuel in the combustion chamber, your engine will sputter and struggle.
A Reduction in Fuel Economy
Finally, all of these things can cause a noticeable reduction in your vehicle’s gas mileage. You will find yourself heading to the service station more often to fill your tank.
