You can eliminate the fuel pump relay from consideration by jumpering it out of the circuit.

Remove the relay (#103) and look next to the pins in the base. Molded into the plastic you should see the numbers 31, 31b, 15, and 87. Fashion a jumper wire and jumper between the socket connections that correspond to pins 15 and 87. If the car fires right up your relay is bad. If it still doesn't run then you may or may not have a problem with the pump. The only way to tell for sure is with a fuel pressure gauge.

If the pump and regulator is working properly you should see 43.5 PSI at the end of the rail.
