mondail 3.2 need help on start stall issue please

The Fuel pump activate during Start with one relay, but there Is anther after, check that

 

What do you mean by "stalls right away"? It stalls the instant you release the key from Pos III (start) to Pos II (run) = could be an ignition switch problem, or a few/many seconds after that = could be a relay problem.

First thing you should do is unplug the safety switch on the airflow meter and turn the key "on" (Pos II) = you should hear the fuel pump run. If it doesn't = put a different ...101 relay in the relay S position (fuel injection delivery pump starting relay). The fuel pump is energized one way in the Pos III and is energized a different way in the Pos II (so the engine can start if the Pos III mode is working, but will stall a few seconds later if the Pos II mode is not working).

 

Not enough information to understand the precise problem, but perhaps a crank position sensor failing? Can do an ohms resistence check on these sensors.
