hi guys, just a quick rundown. i started a thread because after searching i have not been able to find a thread with the same problems as what im seeing. i have a 2007 honda rancher 420 4x4 with the EFI. as of right now it will not start without spraying carb cleaner into the air intake. once it cranks it will not stay running unless you keep spraying it. when i disconnect the injector line i can see fuel coming out when i spin it over. the fuel pump relay clicks when i turn the key on. oh and i can here the IACV hum when the key is turned on. i have also pulled the injector and spun it over with it hooked up and it starts with a good spray and then it gets lighter and lighter till it has almost no spray. im at a loss guys! i think its a fuel issue but im not sure. i dont want to just start throwing parts at it. i really want to know what the problem is. also the previous owner did a top end job on it with a new piston, rings, and a new cylinder. i believe he told me he went with an oversized kit but im not sure.
