My st200 broke down the other day. Turn the ignition on it doesn't seem to register the key. The ignition lights up, engine doesn't turn over, fuel pump doesn't prime and immobiliser light continues to flash.

Removed the coil covers to put the key closer to the ring on the barrel and nothing' spare key the same

Any ideas?

 

Is the light flashing fast when you turn the ignition on, or is it flashing once every few seconds like it does when the ignition is off?

 

The flash stays the same when the ignition is on or off, slow
