I think you are looking at the wrong area of the car. If the electronics didn't come on, this is an electrical power issue, not a fueling issue. I'd check to ensure all connections are good from the ...

Why does the fuel pump buzzing sound go away after a couple of seconds?

Most fuel systems have a pressure-switch. So when the power is first applied the fuel system is unpressurized. The fuel pump is then turned on to build up pressure so the engine can start. Once the ...

How can I start my lpg toyota Yaris with a broken gasoline fuel pump so I can bring it to the specific repair shop?

You won't be able to disconnect the fuel line and pour fuel into the fuel rail because this won't achieve the 60psi of fuel pressure that most non-direct injection fuel injected cars run at. You also ...

Dirt in the tank could definitely be the cause of the burned pin because the burned pin suggests that the pump was drawing a larger than normal current from that wire. The pump having to contend with ...

Is it bad on your fuel pump to have your tank run low?

It is because the fuel lubricates and cools the pump. If you leave the tank run dry, the fuel pump will turn dry, which will overheat it and may cause the electric motor to fail or otherwise to ...
