04 cbr600rr turns but wont fire
Alright i'll try to best explain everything that's going on.
I bought an 04 cbr600rr from someone last month. Road it fine for two weeks(roughly 250miles) then when I went to fill it up at a local gas station(with 91 octane fuel) it wouldn't start. Called up my buddy(Josh) told me to wait a little bit let it sit drink a monster or something and let it sit for a second. After I let it sit it started up fine.. Got it home and tried running it the next day but wouldn't start for the first few cranks, after couple minutes of trying it finally fired up. This would happen about 3 or 4 more times till we finally took it apart and started checking stuff out we re-wired the BAS which was already bypassed and made sure the senors weren't bad. After about an hour we switched my battery with Josh's battery which was in an R1. It fired up right away when we put it in. So I bought a new battery thinking that was the issue and it was fixed. So we put the new battery in and put everything back together. I drove it home and started it up the next day and road it maybe 20 miles came back and parked it in the garage.. I thought well lets make sure it'll still start up. It wouldn't... The fuel pump primes just fine and the only time it won't is if we remove the bypass for the BAS Since then it's been sitting in my garage not starting at all... We have checked all the fuses and every one of those are fine. We have replaced the spark plugs thinking it might be them but still nothing. We have checked the voltage of a lot of the wires leading up to the ECM/ECU. The ground wires seem to be fine. We al At this point me and Josh are at a lose and we can't think of anything else, so any sort of input would be extremely helpful... Sorry for the long read but at this point this is the last thing I turn to before I take it to the shop and drop a ridiculous amount of cash.
