 Hi all,
I hope you can let me some hints on this

It is a C6 2006 Petrol Engine (V6 24V). I was was parked for 4 months (not used) and after that, it never start again.

Problem: I dont have 12v on injectors.

Diagnose: I´ve Spark during cranking (remove a coil an tested)
I´ve fuel on the rail (fuel pump is working)
I have "pulse" on injectors (I have tested it) so ECU is working.
All fuse are OK
Battery is OK and charged.
However I dont have 12v on injectors (it has 3V)
Lexia only found issues on inyectors but we suspect that this is because they are not receiving 12V.

Question: Do you know who is the responsible to provide 12v on Inyectors?
Do you have any wire diagram for Petrol Engines ?

Many thanks !
