1987 rx7 turbo I have power to fuel pump relay. But when I turn key on I have no power to pump. I could be doing something wrong . Just check all my angles. Thanks for reply back

You will not have power to the fuel pump when you turn the key.
The pump is only powered when the engine is cranking or running, via a switch in the AFM detecting airflow or the ECU detecting a crank.
You can jump the fuel pump check connector (see FSM) to make the pump run whenever the key is set to IGN.
What problem are you trying to solve?
