I've also experienced this kind of starting problem in the past when the x-relief relay (J29) has failed. To confirm this, I put a physical switch instead of the relay and manually forced the contact. It's something to eliminate, anyway.

Remind me, did you change the fuel pump relay?

It's behind the dash, where the fuel pump relay and fan fuses are.

Don't just check the fuses, but the voltage coming to the socket when the fuse is out.

After checking +12 on the injectors and the fuel is well vaporize in the prechamber we can not see it in the cylinder by the candle, it is oriented towards the ignition, inversion with one of these coils still no spark, I went from the coast of the PMH sorry to all those who directed me to him , it is not exactly him it is ok it is the cable section of the sensor to the water box it is completely cooked it is disintegrates while fiddling it almost started I'll do it again

On both sides the cables split, which is curious no fault to the Vagcom after no cable break just a resistance that fluctuates and flies awayImage

Is that the crank position sensor plug? I replaced mine as well as it was damaged and without that, the engine will not start.

Sounds like a promising clue, no?

little feedback it will serve the community it was the beam that was defective between the sensor pmh and a connector on the top right the sheaths were all broken and cooked I redid a new wiring with high temperature son a new connector and the whole protects by 600 ° high basalt sheath c I put the cable behind the heat as you can seeImageImageImageImageImageImageImageImage

yes thanks to you it's vicious because it is only part of the beam and the sensor itself

beam = harness in this context, in case anyone was wondering.
