Hi ya,  
just joined the forum, have used a lot of the info on here before now, but I am finally stuck! 
Just had the fault diagnosed after a second no start. It never happens to me, but always the wife ha ha ha! 
Anyway, crankshaft sensor is the diagnosis. Looked/trawled the net but cannot get one where i've looked. can anyone recommend a decent place for this type of sensor, please? 
It looks a bit of a tight squeeze to change too. Any advice?  
cheers
