1988 Mazda RX7 4 cyl

I have a 1988 mazda rx7 non turbo and I just replaced the ignition tumbler. When I tried to crank it it would not start. I checked and there is no power getting to the fuel pump. Is it a coincidence that this happened at the same time, and if so what could be keeping power from reaching the fuel pump? I cannot find any fuse or fusible link that controls the fuel hot wire, but it's dead with the ignition on.
I would appreciate any advise on this subject.

Find the short circuit terminal and jumper it the fuel pump should turn On. If it comes on test the circuit opening relay power comes from here to the pump.

Hi,

It should be on the passenger side of the engine. If you are still having issues, please start a new post because this one is over 10 years old and we will need to start fresh with your specific vehicle and issue. Thanks
