Electricxa failure in the Zetec 1.8L 16V escort

Hello, I would like to know if someone can give me a hand

I have n escort '97 and it has a fault in the start, or rather it starts when you want, it throws it and starts safe, when it does not start it is not because it does not reach food to the coil, check the ignition relay but it is right, it also changes it but it remains the same.
Can someone give me a fact where to look for?

It is not clear to me to start but it does not turn on, or when the key does not do anything at all?

The engine turns normally, but does not start due to lack of food,

I emphasize that it has a new battery, which I later checked and works very well, the alternator loads correctly and has the newly repaired starter.

Let's see if you have problems with the immobilizer or the transfers that goes in the key ... greetings !!
