Honda Ruckus No Start Troubleshooting & Fuel Pump Swap 

Thanks, man! I really appreciate it!

Agreed! With most of the stock plastics gone, they are super easy to work on.

Yeah, that sound exactly like what was going on with mine. I hope the new fuel pump fixes your issue. Good Luck!

@@MikesMiniMotors That was the trouble, swapped out the fuel pump and she's running great!

Awesome! I'm glad to hear you are running again!

I'm glad you liked my video! Good luck with your Zoomer!

Thank you! I really appreciate the feedback!

I'm glad you enjoyed the video! I love my Rolling Wrench harness too!

Haha, when I watched your video about this same issue, I had flashbacks... 😆

Thanks! I am really liking the bar set up I have on there, it feels comfortable to ride usually. The only time I have gotten a bit uncomfortable is on really long rides.

The black piece is the OEM check valve. I don’t have the pulsar unit, as my fuel pump is ran off the OEM ECU.

You could potentially use a multimeter to probe the fuel pumps connector, but I do not know what values you would be looking for to confirm a good/bad pump. Checking the flow is the easiest way I have found to check the fuel pump.

I would check my grounds with a multimeter. Set the multimeter to either Resistance (Ohms) or Continuity. Place one probe on the negative of the battery, and the other probe on the ground you want to check. Check your resistance reading, it should be really low (under 1 Ohm). If you do not get a reading at all or a high reading, you may either have a wire unhooked somewhere or a connection could be loose or have corrosion on it. If all that checks out, I would find a wiring diagram online and start tracing wires to see where the issue could be. Good luck!

I'm glad I could help you identify your issue. I hope your fuel pump swap goes good for you!

Thanks! I got my fuel line here: www.rollingwrenchdenver.com/products/helix-line-kit?_pos=1&_sid=e7be00501&_ss=r&sca_ref=2317757.Ut0lWw890q

They are the Helix fuel lines. I got them from Rolling Wrench. www.rollingwrenchdenver.com/products/gy6-swap-fuel-and-vacuum-line-kit

@@MikesMiniMotors omg thank you sm

See my reply on your other comment.

There isn't a fuel pump relay. Looking at the wiring diagram for a stock Ruckus, the fuel pump gets +12VDC when the ignition is on, and the negative leg goes to the ECU. I used the Rolling Wrench swap harness and with it, the stock ECU and wiring harness stay in and still controls everything.

So when you turn the key on, the fuel pump is the only thing that turns on? Have you checked the fuses yet? That's where I would start looking.

I decided to go OEM with mine. I found it on eBay for around $60, so I felt that was worth the difference from the knockoff ones.

@@MikesMiniMotors oh man thanks for the reply , how's ur pump holding up did u replace the filter as well?

No, my filter was pretty much brand new. I have a clear housing filter, so I was able to visually see that it is still good also.

I just put my new fuel pump.in , and before I could almost stop out at 40mph , now it will only get up to 35 and then will slow down I dunno why all I did was replace the fuel pump , and adjusted my throttle a bit

Hmm, that's odd. Did you go with an OEM fuel pump? When you are getting to 35 mph, is the bike cutting out like it is losing fuel? It is possibly that the fuel pump isn't able to keep up at full speed, but seems very unlikely to me. Maybe the throttle adjustment you did may have something to do with it.

I was using the stock Ruckus fuel pump which is electric, so I just cycled the key on and off a few times and it was good to go. Some GY6 swaps go to a vacuum-driven Mikuni fuel pump though, and those need the engine running/turning over to pump.

You can put your mouth on the gas cap and blow really hard and tilt the bike to the left side and it will fill the fuel lines thats how u prime without a eltric fuel pump works everytime

Mike your should change that fuel pump out again to a gy6 fuel pump not a get one youll have the same problem again down the road if u dont them fuel pumps dont handle the gy6 motor fuel intake

The stock electric pump has more than enough flow for a GY6, I have friends running them even on 232cc GY6s with no issues. I refuse to use the vacuum fuel pumps.

Of all my bike and as long as I have had them, I have to replace only this one... 😄😄😄

They are way better then cheap knock-offs or crappy vacuum pumps...

@@MikesMiniMotors this dudes an idiot
