Check the resistance.

Using an ohmmeter, measure the resistance between the terminals.

Standard resistance

RESISTANCE SPECIFICATION

Tester Connection	Specified Condition
3 - 4	Below 1 Ω
3 - 5	10 kΩ or higher
3 - 4	10 kΩ or higher (Apply battery voltage to terminals 1 and 2)
3 - 5	Below 1 Ω (Apply battery voltage to terminals 1 and 2)

If the result is not as specified, replace the fuel pump relay.
