Chevrolet Astra I turn on the engine and turn off

Good evening I need help with my Chevrolet Astra 2000c.C of the year 2001. I turn on the engine the 3 seconds go out and I can repeat it as many times as it is and the same thing happens again.

Hello friend, it is a little crazy what happens to the car but well, I would recommend that before doing anything you check the current to the car, try to see if the PQ car goes out stops throwing out ... Try that and tell us to see greetings

If it is as if the injectors will run out of current and close no more gasoline and go out

That such a friend
can be the causes of the fault, but because of the way it could go through the key of the key of your car or what they call transponder, look at the board to see if it does not blink a focus in the form of a cart with a key, if so, put the key in ignition that sets the foci of the board and leave it for it about 20 minutes so that it will be
reprogram Chip are deprogrammed for many reasons that the key is hit, by low Vateria voltage etc.

Check that and let us
know

I explain function of the key of the key
when putting the key on the ignition sww the chip sends a computer to the computer, if when you pass 3 seconds the computer does not receive the signal cuts the pulse of injection and stops insectioning gasoline and turns off, sometimes leaving the key 20 minutes it is reprogrammed, but the battery has to be well loaded
