Does the engine management light come on with key in the start position (not cranking)? If not, could be a faulty PCM (computer). Have the vehicle plugged into a diagnostic computer. The light will not stay ON to indicate a fault untill the car is actually running !

NO light at all could be a faulty PCM/ECU (computer) or bad/broken wires to the PCM/ECU it will need to be plugged into a diagnostic computer to see if it can communicate. And if there are any fault codes !

Did the diagnostic computer link to the car and show NO faults?. Or did it show no communication. Also could you check if you are getting a spark and fuel at spark plugs (check for spark and pull a plug after cranking to check if it has fuel on it)?

I would start by checking you are getting power (live feed) and a good earth/ground to the ECU (computer) .. it could be a bad wiring connection/bad wire or it could be the computer has gone bad ... I do not have a wiring diagram for this vehicle .. your local library or autoparts store will be able to supply a repair manual (haynes etc.)with wiring diagrams ..
