Please where is the crankshaft sensor located on the Ford transit 2.0 TDCI 125PS T350?

Question

I'm trying to locate the crankshaft sensor to be sure it's okay and not also responsible for the van not starting, but my search has been to no avail so far. So kindly describe in simple details for a novice like me where it is located. Also, is there a way I could chat with you real-time Mr. Reynaldo, maybe via a messenger service or via email? (my gmail is "s09mailbox"). Please provide yours or mail me on gmail. Thanks a million
