Fuel pump is fine, it run perfectly and building pressure.
However, no signal passed to it.
I believe with 993 fuel pump should run once final stage of ignition closed, the later should close once ECU sees signal form crank position sensor
My suspect is the crank sensor not getting powered by the ECU through terminals 48-49. I just needs to confirm it. Only 1.2 v available at positive terminal. Any ideas??
