I just done some trading for a suzuki 700 king quad knowing that it had a problem with it. All other wheelers that I have ever owned had carbs and this one is EFI. The problem I am having is it will not start. I have fuel and spark. The guy told me that his son was riding it around one day in the yard and it was running just fine. He told his son to park it cause it was supper time so he pulled it up to the house and turned it off. Then a couple of days later he went out to start it up but it would not start. When I got it home I checked the fuel pump and it was working. Then I checked all the fuses under the seat and they was good. The I pull the spark plug and it was getting fire but I put a new one in it anyway. I put a brand new battery in it also. I am not familiar with the EFI on a wheeler so any help would be awesome. Would there be any safety switch or maybe a relay that would cause it from starting.

 

Is the FI light on? any blinks?

 

FL light? Please explain. Only code that I have seen is _COO

 

F1 red light at the top of the speedo, starts flashing if a fault comes up on the EFI system. Clean the fuel filter out in the top of the injector, see my recent posts on "King Quad runs like crap." Check the fuel pressure if you can, should be 40psi or more, if a lot less, the main filter in the fuel tank may be blocked. You have to take off rear plastic and tank to get at it. Trouble is you can mess with EFI systems for ages. I did a 500KQ and went through the whole EFI system only to find the flywheel had come loose and put the ignition timing out.

 

The timing had crossed my mind. But the wheeler was running great the it was turned off it didn't die on its own the it has never started back up.
