Paladin 300 possible dead fuel pump - Page 2

Well crap. Hopefully it's not too long of a wait. I was going to do a Google image search to see about sourcing something in the states, but I gotcha. Let's hope they start stocking these parts stateside

Is that a "returnless" PWM type pump?

Mumen Rider · 11-05-2024, 09:24 PM

No, I don't think it is based upon only being a two wire setup and there is no fuel pressure sensor.

This looks close. It seems to resemble the hawk 250 fuel pump, everything stateside is priced around $120. That being said, if you confirm the pump once you have it removed, I may buy one from Aliexpress just to have on hand.

I thought the pressure sensor is built into the pump, but there's no feedback line (only the two wires for power and ground). There must be a sensor at the throttle body. How would it know when to turn on the fuel pump, or how long to run?

I have contacted Zora/Maxpro llc and included the video of the bike misfiring and stalling. I did the engine code test (hold throttle, turn on, drop throttle after the engine light turns on) and I got no flashing code. It doesn't seem to have stored a fault code. That was a cold start. It seems to run OK for a few seconds, then the symptoms begin. Then it happens every time you try to start it, and I had to twist the throttle some (maybe 1/4 throttle or less) to get it to start at all after it ran for 30 seconds or so.

Looks like you'll be replacing your fuel pump too after watching that. You can plug in an OBD-2 reader under the seat to see if there are any stored codes. Mine had a stored code for low battery voltage which was probably the battery being disconnected while running at the factory.

It sounds like changing the fuel pump will be easier than changing a spark plug! I might do both since I will have the tank off.

Between fit/finish and fuel pump issues, i'm wondering if these are redesigned for the US market and truly first run of the model. I recall mention that the Paladin has been sold previously in other countries, and if that were the case i'd think these issues would have surfaced and been addressed by now. Hopefully Xpro/Zumaav can remedy the next batch and we start hearing of less issues and more positive ride reports.

They're sold in other markets with different engines and they are mostly carbureted. The CBS300/NB300 are the most common engine used in the S8 models followed by the ZS172/175 air-cooled engines, the NC250/300/450 seems to be phasing out slowly. The Loncin engines are "rare" in Ukraine and in Russia they're not "officially" released.
