First time post... I have an 85 GSL-SE and the fuel pump isnt getting voltage. I have removed the pump and bypassed all wiring and connected the pump straight to the battery to verify fuel pump operation. It works fine that way. It seems no voltage is getting to the connector behind the driver side seat rear compartment. Does anyone know if there is a fuse or relay or something that can be the point of failure?

Have you tested the fuel pump relay? The haynes manual has a step by step all you need is a muli-meter.

I just re-wired mine using the info here: http://2ndgenrx7.freeservers.com/techmaster.html



But later I realized there was a cut out switch installed.

well its a simple matter of looking at a wiring diagram and figuring out what part doesn't get 12v. i think power goes from the main relay to the fp relay, to the pump. the relay is activated by the ecu (i think, the 12a is, and the fc's are). i would bypass the relay and see if it works. if it does then its either the relay or the ecu ground. if it doesnt it could be the wiring to the pump/ relay
