Where is the ground wire on a fuel pump relay?
There is a brown wire ground wire at the bottom right of the fuel pump relay socket that tends to push back instead of connect when inserting the relay. Reaching behind the relay box will indicate whether the spade connector has pushed back or not.
Why is the fuel pump in the fuel tank?
It is in the fuel tank because “pushing” fuel to the fuel rail is easier than “pulling” the fuel, which is what an inline pump would do. While being in the fuel tank makes the pump more reliable, it also makes it a lot more difficult to get to. The good news is that fuel pumps are inexpensive.
Where does the fuel pump sit in a gas car?
In modern fuel injected vehicles, the fuel pump sits right in the fuel tank and “pushes” the gasoline to the fuel rail (s). It is in the fuel tank because “pushing” fuel to the fuel rail is easier than “pulling” the fuel, which is what an inline pump would do.

Why doesn't my fuel pump get power?
In most of the cases, it is either a bad fuel pump relay or blown up fuel pump fuse which leads to fuel pump not getting power issue. But in some cases damaged fuel pump wiring, connections or a bad ground path in circuit are also common causes for no power to fuel pump.

Will a fuel pump work without a relay?
The fuel pump operates when the engine is cranked (not running) using power from the battery through the starter solenoid. When you turn on the key, this energizes a relay that in turn provides power to the fuel pump. If this relay fails, there is no way for electrical power to reach the pump and it will not operate.

What controls the fuel pump relay?
It is often found in the fuse box located in the engine bay and functions as the primary electronic switch that controls power to the fuel pump. The fuel pump relay is usually controlled by the ignition or Powertrain Control Module, and when switched on, will provide current to the fuel pump so that it may function.

How many volts does a fuel pump need to work?
System voltage should read 11.8 - 12.6v DC or higher with no electrical loads on the system. If voltage reads less, starting and charging system should be investigated before performing fuel system electrical testing. 1. Connect digital voltmeter to fuel pump wiring at fuel pump connector.
