1990 Mazda B2600i

Hi,
I have a 1990 mazda b2600i (2.6 litre) which seems to be over fuelling intermittently and cutting out. It can run for days and then suddenly stops and won't start again - which is rather hazardous when on a highway! The fuel has been changed, its been flushed, all modules, injectors, plugs and wiring have been checked. However, we cannot find the plug socket to plug the diagnostic computer into to help determine the fault. Is there one hidden somewhere that we don't know about?
We are stuck in South Africa and need to get back to Zimbabwe. The Mazda agents cannot find the problem - can anyone help with some suggestions of what it might be?
Look forward to any help as we are scratching our heads and pulling our hair out!
Cheers,
Lee

If this is right hand drive, check both sides for the plug,

Hopefully you’re not looking of a diagnostic connector like you’d find on an OBD-II type vehicle?
Back in 1990 the Mazda system was OBD-I and not all that helpful; you’d basically only retrieve trouble codes either by using their “diagnostic checker box” or using flash code method of the check engine light.
There are two green diagnostic connectors under the hood close to the fuel filter. One is a six pin (used with checker box) and a one pin connector for flash codes. Once you find the one pin green connector; connect a jumper wire to it and battery neg; turn the ignition on (engine off) and count the check engine flashes.
Not sure if a code will help you with this problem; diagnostic codes do not always have the mystical answer to a running concern; but it wouldn’t hurt to know if there are any and what circuit(s) it may deal with.
For an example of a flash code count for code 23 being flashed from the check engine light would look something like this.
Turn the ignition on, connector grounded; the light would flash flash pause flash flash flash longer pause and then repeated, two more times and then on to another code number if there are any.
