Turn the ignition on without starting the vehicle. You should hear the pump run for a few seconds and then shut down. You may have to listen at the fuel filler door with cap off and a helper to hear it. It you hear nothing then check the fuse and fuel pump relay. If they are good then the pump is more than likely bad. I all seems well, then a fuel pressure test run at the fuel rail will verify the condition of the pump and if it is putting out enough pressure.
first check to see if fuel filter is clogged.if you have an electric fuel pump, check the fuel pump fuse. next check the fuel lift pump. then check the injector pump
check for voltage back where the hot wire connects to the fuel pump. also check groundwire off fuel pump. check fuel pump fuse / check fuel pump relay.
You will need a fuel pressure guage to check the fuel pump. The pump operates at 13 psi.
You can check your 1984 928 Porsche fuel pump with a diagnostic tester. You can also check the fuel pump by connecting the wires to a power source and see if the fuel pump operates.
check fuel pump fuse..
Fuel pressure pump, gets fuel to fuel injector pump, which pump do you want to check and symptoms?
Check to make sure that the pump is getting power to the Neon fuel pump. Check the pump relay, and the pump fuses.
Check the electrical plug at the fuel pump for melt-down damage. Check the inertia fuel pump shut down switch. Check the fuse. Check the relay.
Check the fuel pump relay
Check there is power to the fuel pump via the connector at the tank. Check fuel pump relay and fuses related to this. Or if there is a fuel cutout switch on this somehwere. If not, then need a fuel pump.
Check the fuel pump, fuel pump wiring, fuel pump relay and fuel pump fuse.
Assuming its Fuel injected. check the FUEL pump, or the fuel pump relay. there is also a fuel pump fuse under the hood you might check that first. Your problem is most likely a bad fuel pump. If its carburated check the fuel pump or a plugged fuel filer.
