Mods include an exhaust and vortext ECU. Already did some basic trouble shooting
Changed the spark plug
-put in a known working one and the quad still would not start
Battery swap
-tried jump starting the quad using a good battery
ECU swap
-took off the vortex ECU and put back the OEM yamaha ECU
Added fresh fuel to the quad
-only use 91 octane fuel, always have.
Checked the hose going from the tank to the engine
-was not clogged or torn
The bike was running really strong yesterday. After we stopped to take a break, the bike would not turn on. I tried to starting it for about 5 minutes and it finally started up. Continued riding for another 25 minutes or so. Turned the bike off again and this time it would not start at all! Tried rolling down hill to start it in gear and the bike did something i'd never seen... You could feel the engine running and pressure coming out of the exhaust but the bike would die immediately.
Something to note, the bike was sitting for about 3 months with no use HOWEVER when I went to start it for the first in 3 months it fired up in seconds with no issues at all. Got to the trails and again fired right up after being dead cold for a day. After putting back the factory ECU a check engine light started showing up, no codes at all, the light is solid then blinks until I stop trying to start it.
The only thing I can think of is the fuel pump. The quad use to make a purging sound when I would turn the key. Im assuming this was the pump priming the engine? I dont know. Is there something I can do to see if the pump is working or not?
Seriously if some is able to provide a fix I will donate $50 to you :grin2: would save me a huge bill at the dealer
