If you have a spare key, you could try using that; at least it would prove whether or not the problem is due to the transponder.

If when you switch on the ignition the engine management lamp is flashing it means the transponder chip inside the key is not being read. The engine will not start in this condition. The chip could've become corrupted, but the most likely cause is that you dropped your key somewhere and it split open. The chip will have then fallen out. Do you remember this happening? The chip is small and dark grey in colour. You need to re-trace your movements and find it, refit it inside the key and the engine will then start.

hi thanks for the reply but have checked key and under the cowling round steering wheel and cant find a transponder unit either i checked the older posts on here to some people have said they do have transponders others dont i have checked my key and car and cant find either like i said i have fuel at the inlet to the carb/single point injection so ive been told thats what its and i also have fuel at the return outlet on the carb /single point injection but what im wondering as the plugs and inside of the carb/s/p/i seem to always be dry. could of one of the three electrial components fitted to my carb/s/p/i which all seem to control somthing have failed thus cutting off fuel and making maagemnt light flash thanks
