I have a Mazda B2200 from 1985, which has the same R2 diesel motor, and I had this same problem, which was exacerbated by the cold of winter....even here in a mild Melbourne.
Each time you turn the ignition on, the QSS (Quick Start System) powers up the glow plugs for about three seconds. This recycles again about three times, then.....nothing. The QSS reckons that you ought to have the bugger running by now!
In my desperation, I located the cable to the four glow plugs, and ran a second wire from the battery (+) via a push-button switch which I installed on the dash. This is my glow-plug BOOST circuit.
Now, when I want to start from c-c-c-cold, I push the button (with the ignition on) for about ten or fifteen seconds, which gives the glow plugs a goodly time to heat up the combustion chamber, and when I hit the starter, she usually fires up with a rattle, and a cloud of grey exhaust smoke.
(Of course, once the motor has warmed up, there is no need to use this BOOST circuit, for the combustion chambers are already hot enough to detonate the injected fuel.)
Have a go at it, as I know that it works!

Imagine the white smoke is unburnt diesel. Anybody standing in the middle of it will be able to tell you soon enough.
Most likely culprit is that one or two of the glow plugs aren't getting hot enough. Usually just that the plugs need replacing, but worth checking first that the busbar which runs between them all is getting +12V at the appropriate stage of the process.

Disels are simple, if they have fuel and compression at the right time and in the right quantities they will run fine. You might just have a blocked filter. If the mileage is moderate your injectors or pump might be the problem and the symptoms might have started quite quickly. If the mileage is high, it could be a worn engine in which case it would have got worse over a period of time and you might be using oil. Have a diesel specialist look at the injectors first, then the pump and the engine last unless he can see something obvious.
