Why Is My Fuel Pump Turning Off?

However, engine shutdown of a Fuel Pump could be due to multiple technical reasons which alter its efficiency and thus the cars performance. Cause: Lowered Voltage is a common cause. The average voltage level in which a Fuel Pump will operate — commonly from 12 to 14 volts. An unstable voltage cause occur which disrupts the power from continously reaching the motor ofo pump. Corrosion in the wiring, loose connections or worn out components can impede this flow of voltage which could cause early pump shut-offs and hurt engine dependability. Consequently, experts concur that making sure the electrical wiring connections are clean and sound is a high priority so as to prevent troubles like these, particularly with an older car whose wiring stands more chances of oxidation.

The fuel levels also affect the working of a Fuel Pump. Automotive specialists have demonstrated for instance that if you were to drive those last 5 miles on a fuel tank consistently under a quarter full, the pump will overheat. The fuel helps to cool the internals of the pump down by acting as a coolant, which means running at low fuel levels substantially raises that overheating risk. Studies that were carried out by a leading auto repair association confirm that running Fuel Pump when the tank is empty will decrease their lives, to extend upto 20-30%, reducing costs of otherwise frequent replacements and repairs. Actually, if the fuel level is low the pump can suffer from higher operational temperatures wearing out its internal components faster. Overheated pumps are at an even greater risk of breaking down more quickly, and this outcome is particularly exacerbated in regions where temperatures spike.

Another common culprit is a clogged fuel filter. The Fuel Pump sends fuel to the engine, through a filter that collects impurities harmful for performance. After a while, this filter will start to become clogged resulting in the fuel pump having to work harder and much more difficult to push through leading eventually into possible shut-offs. For the vast majority of gas-powered vehicles on American roads, fuel filters should be replaced at least every 30,000 miles. Surely, it can also assist in extending the life of the Fuel Pump AND they help do this by smoothing out fuel flow to the engine which helps retain top performance and maximize fuel economy.

One of the most common causes for why a pump will not turn on is that there could have been an issue within your fuel relay. This relay sends power to the Fuel Pump as needed, and when it fails without warning will halt fuel delivery abruptly. One high-profile example was a major automobile manufacturer recalling 100,000 vehicles for shutting off unexpectedly due to defective fuel relays. These are the types of malfunctions that can be especially annoying to drivers and frequently occur with little to no warning. If noticed the engine performance is slowing ( sometimes yes and sometime no )and it means you should change your decision of replacing Fuel relay as soon as possible otherwise You could face drive failure.

Fuel Pumps are also influenced by environmental factors, especially very cold or hot temperatures. If fuel thickens when the temperature is low, this can put an additional burden on the pump; during ignition of a cold engine in particular. The pump becomes increasingly stressed in higher temperatures, and it can be even easier to heat up. It is important for drivers who live in areas with temperature extremes to stay on top of how their Fuel Pump is operating, especially during the colder months hot/cold starts can take a toll on the pump. By testing the operation of your pump on a regular basis as the seasons change, you can call an HVAC service company if those early wear patterns are detected and avoid expensive repairs later.

Drivers can significantly reduce the risk of Fuel Pump Shutoffs simply by adhering to a regular maintenance schedule; checking wirings connections, maintaining appropriate fuel levels and replacing necessary parts like the fuel filter and relay. Performing regular Fuel Pump service leads to a healthier lifespan of the part itself, greatly reduces the cost for fuel pump repair jobs and you get an overall better drive.
