Had an rhr in a few months ago. The camshaftpoulie turned at the camstaft ( spie broken ).
If I remember rightly, the camshaft sensor looks at the poulie, so there was no timing problem in the cam/crank waveform.
I will see if I have a known good waveform tomorrow.
The car I was working on would not start.
Compared cilinder 1 injection to battery voltage during cranking. That looked oke, injection at tdc as normally.
But when I removed cilinder 1 glow plug ( so there would be no compression ) I found out that the injection of cilinder on was at the compression peak of cilinder 4. So the injection was at the and of the exhaust stroke.
