Pontiac Grand Am Fuel Pump
Usual Indications of a Pontiac Grand Am Fuel Pump Going Bad
Fuel combustion is the most important process in your automobile. Without it, your engine would not even start. Your fuel pump assists in this process by drawing fuel from the fuel tank and pushing it into the engine block. Your fuel pump electrically works with your system, making it sensitive to high temperature and slightest corrosion. Following are some signs that your fuel pump is going bad:
Engine power loss
Issues with your fuel pump directly affect engine operation and performance. A good example of a sign that the part is going bad is when you experience engine power loss. This symptom most likely occurs when your car is climbing a steep slope. In this instance, your fuel pump is not able to deliver additional fuel for the engine to produce extra power to drive through the slope. Engine power loss may be caused by faults in different components of your car. However, you should not disqualify the possibility that the pump may be at fault.
Unfortunately, you can never be 100% that the fuel that goes into the engine is pure. At times, the fuel carries contaminants such as corroded particles from your fuel tank. Since fuel travels through your fuel pump, these particles build up on the pump assembly, clogging up the pathway for the fuel. Because of this clog, inconsistent fuel delivery may occur, causing a hesitant start that results from little fuel that reaches the engine.
No start situation
A no start situation is a more serious form of a hesitant start. Your Pontiac Grand Am fuel pump may have gone totally clogged to the point where no fuel gets into the engine. This issue may also be caused by a blown fuel pump. This happens when the pump has taken its toll from the constant high temperature it is exposed to.
Absence of fuel pump sound
When the ignition key is turned, a whirring sound-much like a small motor running-should be heard from the engine tank. This sound is very noticeable even from outside the car. This is a good sign that your Pontiac Grand Am fuel pump is functioning well. When you do not hear this sound even though the ignition key has already been turned, the pump may have given in.
