A fuel pump relay provides power to turn on fuel pump. A relay allows small current to control high current-
example- a starter relay-- If you didnt have a starter relay- the big thick starter wires would have to run to the ignition switch, and then back to the starter.
with a relay- you only have little tiny wires running to the ignition switch... when you turn the ignition switch on, a little bit of current goes through the tiny wires to the relay- which powers a coil- which then makes the contacts inside the relay connect- which then allows the high current to run through the big wires to the starter.
kinda simple- but can be confusing.
