The engine starts but stops

Hello friends,
I have a Mazda 323 year 1993, my consultation is the following; The engine stops a few seconds after starting. What could be failing? Will the fuel pump be? I will thank you for your councils about it. Also if they have a diagram of the Mazda 323 injection system.

Look, we need a little more inforacion, only with that is not much that can be done, but it is an importing that you see what type of failure it is, if fuel always arrives and what is cut is the spark plug stream, or the revenge, if it is automatic see if the box has oil. From what you say you have to check a pump precion, current continuity, that would be the first

Thank you for your answer,
it gives me the impression that there is an intermittence. The same thing happened to me long ago and he recovered so far that he failed again. Some have agreed to make a scan. I will try to do what you advise.
