John, having a spare crank sensor is a good idea regardless, however it seems apparent that it is not the cause of your problem, unless of course your no start "fixed" itself during your test. Do you know what switch you turn on to power the injectors? This would narrow the search a bit. As I've stated I'm not familiar with your system however can you "real time " communicate with it via a laptop and if so does it display any active parameters? Such as engine RPM? If so then you could monitor for RPM while attempting to start which I would expect to see, then during a no start event see if it is in fact displaying RPM. Hope this isn't too confusing. Joe
