Post pictures of the bottom of the ECU showing the soldering that has been done.

It looks like there may be a few bad solder joints on the 28 pin connector.

I measured all the lines one by one with the multimeter and it was OK. Yet I stuck it again and does exactly the same. The red light also flashes.

I would recommend retouching all the joints with some solder and the soldering iron and see if that has any effect.

I notice that the red light dim flashes. Either I have it in the ECU or I have it connected to the computer alone.

I would recommend that you try the s300 in a known working ECU from another vehicle or a friend and see if it works properly then.

It is difficult but I will look for it. The problem is that I bought it new and it never worked.

Everything is tested here before they are sold, so it is most likely that it is an ECU issue. Keep in mind that these ECUs are well over 25 years old now.
