Just to add, there should be a fuel pump test connector, under the hood. driverside fender lining. Tan wire with white tracer, electrical connector, nothing plugged into it. If you use a jumper wire with inline fuse to battery +, the pump should run, no need to use the key. In the diagram c8 is the test connector, #3 is the fuel pump relay.
