People like their cars as much as women like their precious jewelry. Therefore, they try to keep it in proper shape. A car owner should be extra careful about delicate engine parts like the electric fuel pump. It is required to monitor the Correct Fuel Pump Voltage to ensure that the car stays in a good condition.
Every electronic product has a life cycle and hence the fuel pump of a car may need to be replaced after being used for a period of time. A car owner should know how to diagnose the problems and how to monitor Correct Fuel Pump Voltage to ensure peace of mind and save money. There are many reasons that can lead a fuel pump to malfunction but it may not be required to replace the pump always.
When a person turns on the ignition key of the car, he should be able to hear the fuel pump being turned on by the PCM. However, if the engine does not start with the first attempt, the fuel pump may be put off. If the sound of fuel pump is not heard it could be due to three reasons.
The first reason could be a faulty PCM. Another cause could be a flaw in the circuit situated between the pump and PCM. The last and most serious reason is a genuinely defunct fuel pump. If something is acting truant between the fuel pump and PCM, a person can test using a DMM or digital multimeter. The DMM needs to be attached to both sides of the pump so that the Correct Fuel Pump Voltage can be obtained.
The car owners should remember that a fuel pump can not display the Correct Fuel Pump Voltage if it gets reduced supply. A malfunctioning fuel pump can lead to a number of car driving problems. If the pump check valve
is defective the starting may resemble a groan. Connection problems, low voltage etc may cause the engine to perform below par.
However, removing a fuel pump and installing a new one can be a tricky job and hence the car owners should make sure that the pump is actually defunct. To get to the root of the problem, one should see if the voltage is being supplied or not. If the pump voltage stays close to the battery voltage, there is nothing to worry. If it does not, the various parts near the pump need to be scanned for errors.
