For valve train noise try these:
1. Low oil pressure caused by oil feed pump not functioning
properly or oil passages obstructed.
2. Faulty hydraulic lifter(s).
3. Bent push rod(s).
4. Incorrect push rod length.
5. Rocker arm binding on shaft.
6. Valve sticking in guide.
7. Chain tensioning spring or shoe worn.
8. Cam(s), cam gear(s) or cam bushing(s) worn.
9. Cam timing incorrect.

If it is a bottom end knock, an engine tear down may be in order.

SOURCE: engine cranks wont start

i do believe that's what it is if it will not let get a diagnostic or if it will not let you access the computer the computer is bad.

The same thing just happen to me and a friend of mine on our 2001 Road Kings. I am 95% sure your problem is the crank position sensor. We replace ours and the bikes are back to their glory.
