Could be a duff ignition coil or ECU (or even missing altogether!), or a loose connection/bad earth. Best to check for power (12V pulsing with the engine turning over) reaching the coil low tension (LT) terminals and go from there.

Find the DME relay (five pin) on the fuse box. Check for 12v at the red wire (12v feed) with ignition on. No power = wiring fault. If there's power there, check for 12v at the red/blue wire (12v to ECU). No power there could be a bad earth (ground the connection to battery earth - ) or a faulty DME relay (very common).
Start there and let us know.
