How long should a fuel pump last in a car?
The fuel pump is located in the fuel tank on modern cars, and problems can occur when the fuel pump either becomes clogged from sediment in the fuel tank or stops working due to wear, usually from working too hard or after long intervals of time. A fuel pump should last you at least 100,000 miles or longer.
What does a constant pressure fuel pump do?
This fuel pump is a constant pressure fuel pump that can operate on two different voltages, high and low. What this means is that the Powertrain Control Module (PCM) can send low voltage to the pump for idle-like conditions when less fuel is required, and high voltage for high-flow conditions such as wide open throttle.
How many ounces of gas does a mechanical fuel pump push?
If the mechanical pump is working correctly, it will push four to six ounces of gas into the bottle. Most mechanical fuel pumps have a weep hole on the bottom of the unit.
How can I check if my fuel pump is working?
Before you check your fuel pump, find the fuse that corresponds to the pump and pull it out to see if it is broken or burned. If it looks fine, check the voltage at the pump itself to make sure the charge that’s leaving the fuse gets to the pump. If this looks alright, then perform a fuel pressure test.
How does the fuel pump work in a car?
The fuel pump is a device that moves fuel from your tank to the engine, supplying the fuel at a constant pressure to ensure that your engine runs smoothly.
What happens when you turn off the fuel pump?
As a car sits, the fuel pressure gradually decreases and modern cars don’t run without fuel pressure. When you first turn the key on your car, the PCM immediately powers the fuel pump to pressurize the fuel system.
