Key start wire! NONE?

[toxsickcity]

hello again,

I have come a long way and just want to be 100% when I start the wiring.. I have diagrams notes and alot of information... but a few thing are unsure!

my SR20DET have a wire from the ignition Start position to tell ect to add more fuel..

my ect & ecu dont have a pin for that! can anyone explain how the starting for this engine is! I noticed something about a relay to up the speed of the pump but my pump will be single speed.

You need to switch 12v through to the STA pin only while the engine is cranking over while starting.

The ECU will do the rest.

so fc does what?

FC turns a relay on to power Fuel pump..
STA does the same thing? sta comes from the ECT to the same relay with 2nd coil... but i dont have a relay like that...
I only have bosch relays with 1 Set of contact & 1 coil
Does FC only turn on the pump only when engine is running? where as STA turns the pump on while cranking! but my question still applies does the ECU need to know when cranking occurs?

so I will do this... Correct?
start wire from ignition key goes throu the autogear inhibitor then to the starter motor relay.. starting the engine when in Park or nutral!

ECU's relay power's the fuel pump's relay + Contact to power the pump.
STA from ecu goes to a 2nd Bosch relay which also allows to power the pump!
