CHECK THE COLD START ENRICHMENT VALVE AND OR THE IDLE CONTROL VALVE. I AM ASSUMING THAT YOUR VEHICLE IS FUEL INJECTED. ONE OF THOSE HAVE GONE BAD.

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!
