Looking For A Wiring Diagram Of Ecu And Ignition Key Barel

[robots]

Hi!

Does anyone have any wiring diagram that clearly show how r32 rb20 or rb25 ecu igniter is powered ?

Or maybe someone knows how is it powered from factory ?

1)

I had an engine conversion, and I think I've powered my ign./fuel pump relays incorrectly.

When I cank the car, fron ON position to START position I don't get any solid power to ecu until the engine starts. Hmmm, hard to explain.

Lets say I connected nissan datascan or emu software and crank the engine, I have to connect to car ecu again, to resume all the data view/error check.

Or when I turn off the engine. I go from ON to ACC position, power is cut to ecu and I have to turn the key to ON position, to restore power.

2)

As for the fuel pump relay.

When I turn the key from ON to START position I can hear the fuel pump prime. It primes as long as I hold it there.

Sometimes after I crank the engine and don't start it. And go to ON again. Fuel pump starts to prime and shuts off in a couple of secs.

The car is ex-carb A31 rb24s.

Basically I had an rb20det engine and wired it in existing vehicle wiring.(splicing the wires etc).

If anyone has some info or some advice, would really appreciate it !

Thanks!
