Relays are
Green = Fuel Pump Relay
Brown = EEC relay
Black = WOT(wide open throttle) Relay - turns off A/C and other systems when extra engine power is needed.

EEC Relay closes with key on, it powers computer(EEC), fuel injectors, coil, and fuel pump relay.

If you hear fuel pump and smell gas in engine bay then most likely issue for a no start would be the TFI ignition system, so no spark.
Good read here on that system: http://www.therangerstation.com/tech_library/TFI_Diagnostic.shtml
