checking fuel pump

1990 sc wont start. is there a switch that will stop the flow of fuel to the injectors? DoI assume the fuel pump is bad if i have no fuel at the fuel rail gauge port? fuel pump relay is good. any thoughts? thanks

I don't know about your year Bird but the later 90's have an Inertia Fuel Shutoff Switch located in the trunk in back of the side panel on the drivers side. Try resetting it by pushing in the button and then listen for the fuel pump when you turn the key to Run.

so if you dont have fuel pressure, a quick thing to check is the inertia switch as someone mentioned, it is located in the trunk. if it is good then you would have to check for power at the fuel pump.if there is power there then a bad pump is likely.
