The light appears to be a red herring. The ecu I have does not have pats internal.

the pump runs. I have a good spark.
so I’m assuming there is no immobilisation iissue.
the car was running when parked.
there seems to be a signal to the injectors as the noise light flashes. But I don’t think it’s strong enough.
move now ordered another ECU. And a crank position sensor.
could the injectors all be at fault ?
but if I put power to them they fire.

so confused.
thanks.
