How To Start A Car With A Bad Fuel Pump?.

Fuel Pump: 9 Things You Need To Pay Attention.

When you shut off the ignition, the fuel pump relay is engaged again, long enough to power down and shut off the fuel pump. At this point, the electricity for the fuel pump is supplied by the oil pressure sending unit. Once the engine is running, the fuel pump relay shuts off. The key here is to produce a small amount of voltage but consistently to the fuel pump. The fuel pump relay is activated long enough to supply the current required to turn on the fuel pump. When you turn the key in the ignition to start your car, the “start cycle” of the combustion engine begins. The fuel pump relay can be located in different places on different cars: under the hood, on the firewall, or near the steering column, to name a few locations. If you cannot find it, check your owner’s manual. The fuel pump relay can be found in most engine bays. In most vehicles, the fuel pump relay can often be found in the fuse box in the engine bay, which is usually a long black box which contains fuel pump relay along with various other fuses and relays. When you shut off the ignition, it powers down the fuel pump. When you turn on the ignition, the fuel pump relay is activated and will supply electricity to turn on the fuel pump. It is usually controlled by the ignition or the power control module. The combustion engine needs fuel to run, and the fuel pump relay ensures that that engine gets what it needs. The fuel pump relay is a necessary component for the combustion engine model to function. (Photo Source: arrow) What is a Fuel Pump Relay? The relay is vital for the function of combustion engines.

Learn how the fuel pump relay works, the telltale signs of a failing fuel pump relay and how to diagnose, replacement costs plus regular maintenance tips. Therefore, problems with the fuel pump relay will result in the fuel pump malfunction, which in turn will cause start up issues.Ī bad or failing fuel pump relay will often show symptoms to tell the driver something is wrong. Whenever the ignition is turned on, the fuel pump relay will supply or “pass on” a consistent voltage to the fuel pump. To “relay” means “to receive and pass on”. The fuel pump relay is the electronic component found on all vehicles with an internal combustion engine. The fuel pump can malfunction due to several reasons, one of which is the lesser known issues with the fuel pump relay. You might be familiar with the fuel pump, the component inside the fuel tank that creates pressure in the fuel lines to push gasoline to the combustion engine for it to run.
