after reading the electrical plan, I think that to have a spark it:
1.press start button
2.the starter motor turns the engine
3.the voltage regulator detects the generation of current / voltage
4.a contact that closes in the voltage regulator, a contact that allows current to flow on the black and white wire which is connected to:
- from the ECU (EFI control Unit) (function: signal that the engine is running? / the ECU is starting its electronic management?)
- power relay (function: allow current on fuse F1 F3 F4)
5.the engine starter after injection and spark off, managed by the ECU
-------------------------------------------------- -------------------------------------------------- -----
in first test I would do this:
1 run the engine with the starter and check if there is 12v at the fuse F1 F3 F4
If ok: the power relay and voltage regulator contact is good
2. engine stopped, disconnect the connector from:
- the ECU,
- the power relay or voltage regulator
and check the continuity of the black and white wire between terminal 30 of the ECU and terminal 4 of the voltage regulator or terminal 2 of the power relay
