After overhauling the cylinder head including changing valves , timing chain kit and injectors and turbo charger.
the engine turns over but does not fire up unless you pull the cam censor out 2mm then it fires up, but the engine management light remains on. i have also checked and changed the Cam shaft and Crank shaft censor. the diagnostics keeps coming up as Sensor correlation.

Have you checked for debris on the cam pulse plate? sounds like a clearance issue between the sensor and the pulse plate.

Good morning,

What are the code numbers?

If you have correlation codes, this usually indicates a timing issue with the chains.

I attached diagrams of the marks for you. To verify the timing, do a compression test.
