Jammed ignition button? Have you cleaned the connectors?

Also, happened to me once, the clutch cable ( the electrical sensor ) was loose and I was unable to start the engine. Took a day to figure it out.

Does the engine even try to start? The started is spinning?

I did disconnect the clutch switch and tried it, also tried jumping the two wires where it plugs into. Seems like everything works except the coils. Starter works great and the ignition plug is spotless. I'm sure it's something simple that I'm overlooking. This is the first major issue I have had with the gv250's. The '08 has almost 30,000 and has never had any major problems.

there is a 2 prong connector beside the cdi/reg rectifier connector....it supplies the signal from the spark sensor  next to the stator.....it is not uncommon for the wires inside to become "de-pinned". look that connector over carefully...it could be plugged together , but one wire may have been "de-pinned" and is no longer located in the connector.

From your description of the coil wires, you have an EFI machine. 2008 is not efi..so don't use the 08 cdi...as that should be a carby...shouldn't even "plug up".

you won't get a coil reading unless the computer is supplying pulses to the coil...

The coil will say GT650 efi and have either an "F" for front cylinder or and "R" for rear cylinder. The "F" coil will work at both locations....the "R" believe it or not , is constructed cheaper and fails quicker.

the stator connector and spark control connector are underneath the seat frame, and you can see them after removing the cover that holds the seat release. they are usually inside a rubber wrap that looks like a blob with a chunk of rubber over them.

1100 miles is the magic number to have a cooked (discolored) stator connector and crumbly and de-pinned spark control connector

Thanks. It is a carb. not fuel injection. The connections and pins all look intact and look like new without any corrosion.

Is there a starting point where I can start checking to see where the problem starts? I have a multi meter but don't know what settings I should have it on and what route to start checking. Or can I use a test light?

The pick up coil is showing 5.36 ohms at plug, on the other bike it's showing 135ohms. Think it's safe to say that is the problem?

my manual says 90 to 110 ohms for pickup coil....looks like your taking the cover off....use the hylife trick and lay the bike on the right side
