1992 V8 automatic land rover discovery won't start off the key.

What is your question?

The ignition switch tests ok. The starter motor is ok as when I by-pass it it cranks over. There is no power going to the starter motor. Is there any other common problems with this vehicle that I should check? Where is the inhibutor switch located? And is there any other fuse boxes in the vehicle other than the one under the steering wheel? Cheers Tom
