Cranks but doesn't start. Please help!

Ok I was riding when all of sudden my bike died. I tried to start it but it just cranks and the fuel pump doesn't prime. Here is a list of what I've checked already:
1. BAS (fine)
2. Relays (fine)
3. Kill Switch (fine)

Here is what I've diagnosed so far:
1. FI fuse keeps popping
2. No smell of gas upon full throttle starts
3. FP does not prime
Can anyone help me?

fp not priming, but engine cranking is a classic set of symptoms for a bad BAS

how did you rule yours out, as being fine?

if you jumped it, that means you bypassed the BAS ... did it start with the jump in place....? if so, that almost certainly means the BAS is the culprit

It still did not start. Fp relay just clicks and and but turns over but bike still won't start.

I'm positive I'm not getting any fuel. today I will trace some wires in search of defects and check the FP with 12v directly. Ill update if this fixes the problem.

I believe the cause was a intermediate FP relay and a bad battery.
