Um what you could do is have someone stick their ear to the gas tank when you turbn the ignition on to see if they ehar the fuel pump prime or not. That will tell you if tis working.

 

The fuel pump is working.
I turned it in for a checkup in a mitsubishi workshop today to get a definitive anwer what is wrong. It is certain that it is an electrical problem. However, I have been unable to find exactly what it is so far.

 

One new ECU unit later the car is running perfectly again.

The first advice in this thread proved to be correct. Thank you all for your tips. I have learned a lot about the "new" car I just bought from this experience.

 

Ive always found you learn the best when you get problems.

 

So very true.

Funny thing is, after replacement of the ECU the C-Lock works as well. I did not think that the two would be connected. I see no sense in having the C-lock circuit connected to the ECU. But obviously it is.
