fuel pump on 1991 Ford Explorer

Can you help me with a fuel pump diagnoses step by step , the trouble shooting procedures

Asked by for the 1991 Ford Explorer
Check power and ground to the pump while cranking the engine. If you don't have both, then diagnose the fuel pump electrical circuit. If the signals are OK, then you will need to check the fuel pressure output from the pump.
Let me know the results and if you need any other info.
