VW Eurovan 2.5 truck does not turn on

The truck does not turn on, there is no spark in the coil, which has been so far is checked by the rider's position sensor; al and the computer, without emabrgo it still does not start. I do not know what the most check or if the values ​​that the firing position sensor throws me; to the correct ones (values ​​from 0 to 1.8 V alternating current) something I have done is that I disconnect the style of the position of the crap; al and then generates spark in the coil, without emabrgo it takes to start and not accelerate enough. Could you help me? ... thanks

The spark is generated by that sensor if it is with Chinese eye it may be that it is very far from the teeth to read and that is why it does not start, now if you disconnect it, it may be that the computer is accessed in a state of emergency, but it is not very caused, it is rare what you say these surely does not have two position sensors.

I have continued to check the truck, and it has a hall effect and the firing sensor; al, in fact that it starts is that the one who is sending the se; to the engine to start is the hall effect.
Although also check the stiguer sensor; al and his se; the alternating current is fine and reaches the computer.
Now everything seems to indicate that it is the computer and send it to check to a laboratory and they tell me that it is fine.

The spark does not go through the computer, it is a separate system, mmmmmmm tay sure that the sensors and the coil like this are well.

The coil is fine, was the first thing I thought it was, so I changed it and nothing. I also try it in another truck and without problems, as well as the rider's position sensor; al; This also tries it in another truck.

What is rare is that suddenly it began to accelerate well and Caundo started fixing the cables to position the computer and put everything that had already moved the cables, began to fail again and Asolo accelerates up to 3000 rpm, does not give AMS of those revolutions.

After that sudden event, I thought it was a false contact or that a cable was open at some point, to which the resistance in each line was verified again, but it is well.

The truth does not know what the most fuck him.

Greetings.
