EUROVAN DIESEL 1.9 TDI does not start

I'm going to checar, I think it's the camshaft sensor

We know that a diesel engine the only thing that needs to start is the fuel since we already have the air, to generate the injection pulses we need the signs of the crankshaft sensor and the camshaft, we also know that this is a 1.9LTS engine with pump injector.
Well, it has happened to me that the generatrix of impulses that is mounted on the crankshaft and the CKP signal correctly, to verify this you need to check both signs with an octiloscope and see that they coinsidate with the graph that I added to you. Another thing that happened to me and having as a reference the lack of power that you comment is that the escape is completely covered by what I suggest you take off the escape multiple and try to have if it starts there, another issue that you have to ensure is that the pulses to the injectors reach them correctly and that the harness that goes under the cut of the butt is not damaged.
