    Default not getting power to my fuel pump

    Hey guys, i just bought a 1986 supra for cheap and I need some advice. I'm not getting power at the fuel pump except when I jump the b+ and fp terminals in the test box. I've already checked all the fuses, the fuel pump relay, the main efi relay, and the circuit opening relay. Replaced the fuel pump and the fuel filter is new. Any advice on what to check next would be appreciated.

    How are you checking it? Cause the fuel pump will only run when the Ecu sees a air flow signal.
