Ignition assisted to Wagon R

Hello good.
I acquired a 2002 Wagon R 2002 to repair;
According to the engine just done.
He came with the bad box, which is already re -re -reached. I am well.
I turned on the check Engine and the battery icon, but it turned on well and loaded its battery.

The first failure is that on occasions the motor revolutions do not pass from 2000 only until the 2 battery cables are removed.

The second fault that is the recent one has been a chain of events:
one night when turning off the vehicle, it accelerated a lot and turned off. When the gasoline pump was not heard immediately.
He got off the tank and the pump was changed (the withdrawal was good) but I noticed that he was lazy from the plug, so it was thought that it was.

After that incident the car did not want to turn on itself.
Light or "pushed" or placing a few gasoline droplets by one of the air inputs of the immission body.

Injectors, pump pressure, gasoline hoses, gasoline return valve, IAC sensor, TPS .... The cables of spark plugs, spark plugs and distributor cover were reviewed and tested.
The scanner was put but indicates open circuits and reads nothing.

In the midst of this fault, the start, the carbonera is changed.
The time chain was also damaged and the kit was changed.

Only to the incident of the gas pump light alone.
The fault is only in the start, after there it is fine, it does not go out or accelerate, it does not heat ....

we no longer know what else to try ...
it adds any clue or help.
Thank you.
