Your correspondent is told by the internets that poor hot starting is likely to be caused by a dodgy crank position sensor, like this:
So I’ve invested a modest sum in one. Sadly though it has to be fitted as well, which involves starting above the engine and removing bits until you can kind of reach the existing unit, extracting a T30 bolt, extracting the sensor itself and finally getting the new one in and reversing the procedure. All of these stages can go wrong, not least in getting out a bolt that has been sitting there rusting away quietly for fourteen years so I’ve been told that the cheapest option (the official way is to drop the engine) is to use a ball headed T30 bit, like this:
First tool shop I went to expressed some surprise that such a contraption would actually do the job asked of it but once I swallow enough brave pills we’ll see.
