Hi everyone I have an insignia 2.0d, I have issues regarding starting, it won't. I have gotten the following codes from my scanner P2282 (I replaced MAF sensor),P0101, P0403,P0193,P0113,P2100,P0344,P0016(REPLACED CAM AND CRANK SENSORS), P0336. I need advice as to which if any of these faults are related or 1 or more being a consequence of each other if that makes sense. I know my fuel filter needs replacing and I also think my timing belt also needs replacing. The car rotates but is not firing at all not even a whimper I just run the battery flat. My intention is to change the timing belt and fuel filter. Is this the best place to start and take it from there. I did have the dreaded low oil pressure problem but fixed that by replacing the pickup seal. Any help at all would be appreciated. Thank you.

I would change the cambelt first as if it is slack it can generate codes for crank and especially cam sensor as the two are out of sync
Also, ensure the fuel is going to high pressure pump....maybe also change the filter first to see whats in there
