No spark or power to fuel pump HELP PLEASE

Hey guys, I just picked up a 2008 KFX450R off a buddy for 900 bucks. Has a bent A-arm and a no start, the hour meter on the bike only reads 54 hrs on it and over all it isn't in all that bad of shape. I am coming off of a Honda trx700xx, it got stolen from me a couple months ago.

Now that my intro is over with, here is what I've got going on. I've got no spark and have no power going to my fuel pump. The things I have checked
Checked fuel pump fuse-good
Swapped out relay with fan relay and i have power on all wires except the white with a red tracer wire.

I had to stop for the night but am looking for ideas on what to check next, with it having neither spark or fuel i was thinking it has to be something related with each other. Any advices or help is welcomed!

54 hours is nothing! Check eBay forever a used a arm.

I've checked it and it is good, bike turns over fine. And good deal, hopefully once I get this issue figured out and the a-arm fixed I'll get some good use out of it!

Another thing, I've got the green light on and one red light on when cranking over.

Green light is the neutral...!

Far left is the F.I light...If it this one...check for DFI errors...see pics

ground the orange wire to the frame, turn the key on & the F.I light will blink to an error...If any...??

Thank you, I will check that this afternoon.

What're some of the things that will kill both spark and fuel? Roll over switch? Will a kill switch?

Yes both a kill switch & Roll over switch will cut spark & fuel...!!

Check if the roll over sensor is on it's bracket, if yes, then check it's output voltage...!!

Jumped the hot and ground on fuel pump relay and the fuel pump runs. Pulled the roll over switch apart and the circuit board looks burnt. I am going to order a bypass for it and atleast start there. I have battery voltage at the yellow/red wire on wire, so shouldn't I have spark of am I missing something?

Also, is there any reliable way to temporarily bypass that roll over switch?

If the vehicle down sensor is bad, then no, the ECU triggers the fuel injector & ignition coil on a negative pulse circuit...But the Y/R wire needed to be checked for voltage, in case of bad or dirty connection...!

here's the KMS bypass... https://www.kmsperformance.com/shop/item.aspx?itemid=9
