Fuel Pump Relay

WARNING: This page is about a different car, the 1990 Daihatsu Rocky and 1990 Daihatsu Charade. However, it is still accessible from the selected car via links, so may be relevant.

Fuel pump relay receives power when ignition switch is turned on. ECU controls the ground on the fuel pump relay. When ground is completed, power is supplied to the fuel pump for fuel pump operation. See Fig 1 , Fig 2 , Fig 3 and Figure .
