Check if you have an black and yellow relay with "open circuit relay' written on it. That would have the old fuel pump wires going into it. on my 3sgte and 4age the relay was mounted on my ECU.

There is also a dedicated Fuel Pump Relay on some cars. It is connected to the Circuit Open Relay, as on my 1GGZE install.

The power to the pump is usally a blue wire.

Check my tech thread on relays:

Consult a wiring diagram and/or TSRM. Shouldnt be hard to trace your existing circuit and graft it in. Fuel pumps should never be run solely off a circuit opening relay. Use a seperate relay to supply power to the fuel pump(s).

Exactly! Good advice Kebin.

GZ20 ... Blue Wire Red Trace leaving the 'Circuit Opening Relay'

should red 12volts+ on a multimeter when you turn the key to Start.
