VW Transporter 2.4 Diesel does not start

Hi, I have a VW Transporter 2.4 Diesel to which a botator was broken. To which the lid is taken away and the broken bad is changed. When putting it I can't turn it on. I already check the tuning of the distribution and the pump, look at the heating, the air filter and the battery, everything seems normal. The engine rotates quickly but does not turn on help please

Check by taking the engine compression is likely that there is some crooked valve or other crooked valves. Discuss that there is hermeticity in the valves, there may be low compression in the cylinders or with the compressimeter discard that first.

If it is fine with compression, and the distribution well left, it has to tear you away .. Pacicity to purge the injectors at the start ... It takes time sometimes for a while.

What system is it, I have not seen but is it a conventional electronic system? Cr?
