Hello guys, this car still has a problem, the problem was that it was an intermittent non starter with cold engine, there where no fault codes. Because these engines are know for bad chains, that is why I asked for a know good. My capture was a little bit off compared to the one Robski posted, so a new chain kit was mounted. The bad thing is the problem is still the same. I was lucky to catch a capture when it would not run, this capture is attached. Also I made capture when it did run, there I saw something strange happen, in the begin of the capture the camshaft signal goes down at the 27 tooth after the missing tooth,in the end it goes down at the 29 tooth. Sorry but I can not post the file because it is to big. My idea is something causes the camshaft to move during the running. What do you guys think and what could be the cause, and can it be the reason for intermittent not running.

Hello Robski, no sorry I do not have a wps(is on the wish list). The attached file shows that there is one injection pulse at start and then disappears, also channel d was hooked up to the coil drive, as you can see no drive to the cop.
