Hello, I have a Link G4+ Thunder ECU with a custom wiring harness and I have a problem regarding fuel injectors. Injectors work when are tested with the default testing mode (Injector Test), but when cranking, the ECU doesn't output any signal to the injectors. We checked our trigger timings and are correct. What else do you think there is for not injecting fuel when in normal mode?
The above problem occurred suddenly today, with no signs of it in the last year.
