Long story short my 2001 f4i wouldn't start ... a month and multiple purchases later, I found the problem and wouldn't have had to buy anything... here's the steps I went through hopefully this will help someone in the future with a similar issue. 
- Was getting no fuel pump but after hot wiring it... it turned right on.
- No headlights but after testing... they had power but bad ground
- Strangeness... With the brights off... the engine kill switch would turn the brights indicator (on the speedo) on and off.
- Checked all fuses and none were blown
- Researched and saw the ignition switches on the f4i's go bad... so I bought and replaced ignition key switch... still broken.
- Found a whole new wiring harness on ebay (with relays for about the same cost as just purchasing new relays) and before replacing the whole harness I swapped out the relays (there are two in the tail section and one underneath the airbox)... still broken.
- Went to the stunt spot pulled a ECU off a friends bike and swapped it to test ... still broken.
- Decided it was time to replace the harness...
... cranked some tunes in the garage... stripped the bike and started pulling apart the harness. - Pulled apart molex connectors and as I pulled a white molex apart under the airbox a piece of plastic came out...
I inspected it and sure enough connection in that molex was broken and bad ... (Green wire which was a ground). - Soldered the green wire together outside the molex... electrical taped it... FIXT!!!
