03 600rr Won't Crank Over. **Resolved bad fuel pump Relay**

I know theres hundreds of threads but nothing I've seen really equates to my issue totally, just looking for some input/help.

Bike was running fine, sat in the garage over the weekend and now it won't turn over. No fuel pump noise, it does crank but doesn't fire.

Two weekends ago it fell over in a trailer but started up just fine after and has been running fine up until now. I'm wondering if the tipover sensor finally decided to work it's way to a goofy direction.

I've checked the fuses by the battery, all seemed fine. Battery was tested and tested good but low on charge, so I charged the battery and stuck it back in with no success. I do have a killswitch from a 1krr but it hasn't given me any problems at all since I installed it at the beginning of this riding season.

Hoping someone can give me direction, I wasn't sure if the tipover sensor would make it so the bike doesn't even crank or not.

Edit: Forgot to mention that a month or so ago it got really hot here, rode the bike and got stuck in traffic, never died or got past about 235 degrees but after I shut the bike off it wouldn't start at all, no crank, no gauges, etc. Could be relevant info.

Update,

Relay underneath the left fairing was bad, replaced all three just to be safe.

After replacing the relays does the fuel pump prime now or not yet ? In addition as far as the bike getting really hot it's well known for the 03/04 generation that when the Rectifier / Regulator gets extremely hot the bike will not start until such device has cooled off & turning the high beam off when stuck in traffic for example is a common smart practice to follow as it helps with the work load bring put on the RR & the battery at the same time

If your fuel pump is priming now then the problem was not with the BAS sensor which is a sign that the sensor is ok . To avoid fouling the spark plugs do not roll the throttle while attempting to start the bike hold it wide open yes wide open while hitting the starter button & to conserve battery juice take out the headlights fuse that little bit of battery juice will come handy for sure .

Attempt to start the bike like four times in a row if it does not start wait for a few minutes then try again do not attempt to test any lights just to make sure battery got juice that will only hurt the battery more than anything . It takes a huge load to get the starter , fuel pump going so conserved battery is the way to go

It started right up after changing the relays out. :)
