Please provide a wiring list (must always be present, wether universal harness or made from scratch, since impossible to do the essential verification measurements without them anyway)
- outputs
- injector shared + (flyback EC36/23)
- grounds
- inputs
- is it possible to see the measurement notes related to ground and flyback measurements ?
- or do the measurements now and take notes ?
- Ohm measurements, with ECU disconnected. For ground wires, mV measurement would be superior, with 2A flowing through (eg. break-light bulb or 25W bulb would be awesome, <30mV drop over any wire + connector pin)

Measurements i have already done on all Grounds and the + connections.
Grounds = exact same everywhere
Measured from pin to chassis and from pin to pin (ohm of course)
Dont forget please that every output works if the Engine dont run.
When the Engine runs it does not send Ground to the relay for fan and fuelpump.
Changed the output already and problem still exists.
Measuring woth lightbulbs and special Measuretools not easy in my garage because i only have a multimeter and 1 battery.
