Obd diagnostic - forever flashing


Hello all,

Nice to be here. I’m from Lisbon, Portugal and just got myself a brand old 2000 Terios for a personal project and to play in the mud.
The car needs a lot of caring. I tried to run the auto diagnosis (pins 4/6 jumped) however instead of getting the flashing g codes like I’ve seen in different posts on this forum, mine blinks the EFI light forever as soon as I turn the key. So I cannot read whether there’s any error code (neither um will my China obd reader do). I have a rough idle and a smell as the mixture is too rich... back to the diagnosis, what does it mean to have the efi light blinking forever, anyone?
