When is the fuel pump relay turned on?
The fuel pump relay is an important component of the fuel system of your vehicle. The fuel pump relay gives the fuel pump power when it is time to build up fuel pressure in the rail. Whenever you turn on the ignition of your vehicle, the fuel pump relay is turned on. There are different reasons due to which the fuel pump relay fails.
Can a 20 amp fuse cause a blown fuse?
The most common amperages are 15, 20 and 30, and replacing a 15 amp fuse with a 20 or 30 amp, or a 20 amp fuse with a 30 amp, may result in a blown fuse. Worse, it could cause a more severe car electrical problem, because it can cause wires to melt.
How can you tell when your fuel pump is not working?
The pump itself is usually located inside the gas tank. There are a handful of symptoms to look out for that could indicate a problem with the fuel pump: Slow startup: If the engine takes a while to turn over once the key is turned in the ignition, the fuel pump may be having an issue getting enough fuel to the engine.
Consequently, if the fuel pump relay has an issue, it will cut off power to the fuel pump. Also, if a relay overheats, the electrical contacts inside the relay can short circuit; causing the electrical flow to stop. However, when the relay contacts cool, it will resume the flow of electricity.
