Thanks Blue62.
Excellent info on the DME codes and dash number.
It is firing just not starting (I should have been much clearer).
When the guy has replaced the battery I will do the throttle reset (Turn key to on position for 1 minute do not start. Turn key of for 30 seconds - retry).
I will also check in the Autel for a read out of the throttle pedal potentiometers to make sure they are both operating and sending a correct signal to the DME.
I believe from my research that one signal should be approx double the value of the other? Is this correct?
Once I have done more trouble shooting I will get back to you.
Thank you so much for your time and advice - very much appreciated.
Paul.
