all right.
got fuel pressure.
I worked on a Saab one time ...........checked everything 'a lot' ........
finally decided it had to be the ECU. It was.
not saying that's where you are yet though.
re LED for testing injector pulse.
you could put an LED in the place of an injector, observing polarity.
I personally can't say is a valid test though. Perhaps others can.
