Weird MC engine problem

Just a quick update, because access to the car is limited. I'm going to see it again
The garage investigating the problem now suspects a temperature-related issue with the crank
sensor. They say a scope trace shows that signal dying just before the engine does and not
returning until everything cools a little. They also say they've found classic tie-wrap
damage to the screened cable.
My scepticism is because of the lack of ECU codes and the wierd way the ECU holds the lamp
driver high. Maybe there's a bug in the MAC14 code we haven't found yet.
Anyway - playing again tomorrow. Will post final results.
