Car came into the workshop running with oil light permanently on and noisy valves, timing belt cracked 140,000 km.

I have replaced timing belt, oil pump belt, disassembled oil pump for cleaning, phase done with special tools and assembled everything, but it won't start.

It seems to start with a cylinder or two, but then it does not start. Only once did it start for a few seconds, but it did not pick up the revs; at the moment it started, the oil light was off and the valves were silent.

No errors in diagnosis.
