2002 Honda Rubicon No spark, “- -“ on display screen instead of gear position.

Okay, so I have a 2002 Rubicon 500…bought it last year and it sat for several months until I put a new rear axle in, FINALLY got that done and was super excited to finally have my wheeler going, just to notice a strong gas odor. Popped the seat off and sure enough, pouring gas from the carb overflow. Fast forward a few more weeks and get the new carb and get it in, no leak! Yay. Except now I have no spark. 😒 I’ve tried another plug and checked and am getting no power to the coil pack. I’ve read and read and mostly what I’ve found is ECU, which is fine…but I like to exhaust all avenues before buying the more expensive parts just because I don’t wanna spend the money and it have ended up being something simple that I overlooked because I was trying to rush. 😂 I don’t know if it’s relevant, but I read on another post that someone had similar issues with theirs and it was the sensor on the side of the carb, just a thought since this literally happened after I put the new carb on. It also displays “- -“ on the display screen where it should show the gear position.

You need to download a service manual and it will tell you what that sign on the dash means . and what to do about it. It will lead you step by step through the diagnosis process to find the fault..

Suspicious only happened when you changed the carb, there is a throttle sensor on the carb, you might check that for proper function, also a lot of wires in that area you might check to make sure nothing got unplugged. Those carbs are fairly high tech and a new one may not be talking correctly with the ECU, depending on whether its OEM or aftermarket.

The manual says it will set a code if the throttle cable's been disconnected.. You need to refer to the manual HPorter..

Quit messing with it during the cold snap we had. About to start digging back in and seeing what I can figure out!
