i have a 1985 rx7 and my fuel pump stop working but i took it out n test it n it works good..i also took the relay n it work soo i guest there is a fuse that is not working because im not getting power where the fuel pump is connected n i wanna know where the fuse is...thank u

 

fusebox under the dash, way to the left. not sure which one it is off the top, might be the one labled engine.



the way it works is that the trailing ignitor sends a tach signal to the emissions control unit, and this turns on the relay which runs the pump
