Can you splice wires on a fuel pump?
Tin both wires, overlap them and solder directly together. Use a solder with a lot of silver in it. Then use heat-shrink and seal it up good. This is the best way to splice and the method they teach in most military electronics schools.

What are the pins on a fuel pump relay?
The relay should have 4 pins on it. They are usually labeled 30, 85, 86, and 87. Steps: 1. Wire pin 85 of the relay to the 12v supply wire from the stock ECU that you just cut. This 12v wire will now energize the relay to turn on. So now instead of the stock ecu energizing the fuel pump, it will energize this relay. 2.
What happens if the fuel pump is not wired?
It is the device by which fuel is delivered to the engine. If the fuel pump wiring is not done correctly, the pump will not work, and the engine will not run. There are two types of fuel pumps: those that mount inside the fuel tank itself (standard pump), and those that mount underneath the car, just in front of the fuel tank (inline pump).
