The spark is cut

Hi. I have an American Vortec v6 engine blazer. The problem is that recently I took the engine to do several things and now I put it but it does not start. The spark is cut when it starts. When in contact it throws a spark that is too small but as I said when it starts it is cut. It has captor, coil, cover, rotor, cables and new spark plugs. Apparently naphtha comes to him. The injectors are new. Help

If the spark is cut off at start-up, check that voltage reaches it when starting. When the starter drum fails, it can deliver voltage in the contact position and is cut when turned to start. You turned the engine manually to test the spark in contact position, without starting.

When he is in contact he throws a spark, when I start anything and when I turn the key he throws another. I don't think the drum is because all it does is turn to pull a bone bolt, it has no wires or anything. I also didn't find a starter contactor or something

In contact, check the place where 12V arrives from the ignition key. You can put a small 12V lamp between that point and ground, so that it turns on when making contact. Then you start and the light must remain on. If the voltage is not lost, you must test the ignition sensor.

... if there is a spark when passing the switch and another when removing it, it is most likely that some negative coil cable has been stepped on, if not, check the module ...

The module is new too, I forgot to say it. I will check the cable. Thank you

The technicians do not talk about "new" we talk about good because it has been tested, I have already asked customers for module and they have brought it to me new but bad, in their box ...

The truck also worked with that module. I had changed it because I thought that the fault I had before (for which the engine was disassembled) was produced by it.
