A club member is having this issue. He also had problems with locking, remote, boot opener etc. which turned out to be a blown Security System fuse (F4) in the boot.
The car was working up until he wanted to investigate a slight misfiring upon regular driving. (He did find a crack in the frontmost coil/sparkplug cap which he ‘remedied’ with a shrink-tube.
After putting everything back together, the car would not start. It cranks but will not fire. All fuses checked (even a selection in the rear compartment has been checked.)
Any wisdom on this? I know I have been faced with this before but cannot remember what the culprit was.
