Just replaced a fuel pump but when the replaced fuel pump was tested, it worked fine. There's no power getting to the newly installed fuel pump.

Does the mr2 have a fuel pump fuse? I've noticed people on 2carpros have solved their fuel pump problems by checking this one. I've been looking for it online and in some manuals but can't seem to find it. Any help on the location if there is any?

Also check the EFI main relay, airflow meter and EFI fuse-

Try this-in the check connector/DLC jumper the Batt to Fp terminal and turn key on -do you hear the fuel pump?

Fuel pump receives its power supply from the Circuit Opening relay, ( front corner of rear luggage compartment, below the ECU) which receives its power from the EFI Main Relay.
