[[left]Hello friend, as your colleagues have mentioned, your compression is low.
If you have spark and fuel, it's more likely the engine isn't synchronized. Have the engine timing checked,
and also make sure the injectors are working correctly. Sincerely

Hi: Don't forget the cylinder head plan and a hydraulic test is always a good idea. When it overheats like that, the head might be damaged, which could explain the low pressure in those cylinders. I hope this helps.

First of all, greetings to all my colleagues. In any good diagnosis, we have to check, step by step, the components and factors that influence starting.
As we all know, for a vehicle to start, it needs fuel, spark, and compression.
Starting with these three factors, you say there is fuel and spark, and with the data you gave, the compression in the cylinders is low, but sufficient for it to start. So we have to check other factors that could influence it,
such as checking that the spark is adequate (blue color) and not deficient; that the fuel pressure is correct and not low; that your firing order is correct; that all your injectors are pulsing in the corresponding cylinder and not in different order; and that your starter motor is delivering the necessary revolutions to generate enough impulse for your engine to start. Because in most of these cases, they are just minor details that we overlook, but they are important for proper functioning.
I hope I can help you. Regards.
