Spiders do not have a combi-relay like the V6s. Rather, the Spider uses a separate relays; a drive relay and a main relay. Both relays are located by the fuel ECU behind the right seat.
This is when the engine is running. In a start condition, presumably because of insufficient pulse frequency from the coil, there is another circuit that energizes the drive (fuelpump) relay. This is the start signal that originates at terminal #50 of the ignition switch (the same signal that energizes the starter) and terminates at terminal #50 on the fuelpump relay. This same start signal also powers the Thermo Time Switch (TTS), Cold Start Injector (CSS) and provides a start signal to both the fuel and ignition computers (ECUs).The drive relay is supposed to get a tachymetric signal (from a sensor wire at the coil) for it to supply power to the pumps.
Yes indeed. I sorta glossed over that detail when I indicated the fuel pumps are energized during cranking (& running) but not by merely switching the ignition to 'on'.In a start condition... there is another circuit that energizes the drive (fuelpump) relay...
