Have you checked the ASD (Automatic Shut Down) Relay? Check to see if that is getting power. Then check to see if the ASD Relay itself is good. You do not have to use any special tools/knowledge to check this. You can change this Relay out with another Relay that is the same shape and type on a function that is known working. For example: Check to see if your Front Windshield Wipers are working. Change out the ASD Relay with this Front Windshield On/Off Relay. Check the Wipers again. If it does not work, then the ASD Relay is bad. With the Front Wiper Relay in the ASD now check for power to the Fuel Pump Relay.
One additional fact: IF the Crankshaft Position Sensor is bad the Engine will not operate at all, meaning there will be no power sent to anything including the fuel pump relay!
