chrishutt said:Which is the point the OP made to start with, which everyone (except me) seems to have been overlooking. Lots of possible causes of ignition failure, but why should any of them stop it going to lock-out after 5 or whatever attempts?
No Chris, we, or at least I, have concluded that it is not getting to the ignition stage. It can only lockout when it has reached, but failed, the ignition stage.
