Blown Fuel Pump Fuse

[gseale]

Greg, Just to double check unplug the fuel pump and turn on the key see if the fuse blows, have you done any thing else with the wiring just recently? Sorry but I gotta ask.

Don't be sorry - these are good questions. You never know and it doesn't hurt to ask. Unplugging the fuel pump and turning on the key does not blow a fuse. It does register a fault code - 33 | fuel pump short to ground, which we would expect.

I have not fiddled with anything. I went for a casual 45min ride last week and put the bike back in the garage. Tried to fire it up on Sunday, and started popping fuses.

So, after putting in the new fuse and plugging the pump back in, I turn on the key and the pump primes but did not blow a fuse. I hit the kill switch - off, then on and now blow. I did this two more times, pump primes (whining like it always did) and no blow. When I start the bike however, it runs for 10 seconds and then the fuse blows.

It does sound like it time to pop your pump out, Drop your shock, lower the swing arm and out it comes, you can make a puller or be careful and pry it out with a couple of flat tip screw drivers as I have done,
Here are a few pumps to ponder over.

That is such a drastic different in price VS an OEM fuel pump. Simply amazing. Is it the same in every way in terms of functionality?

Don't open the package on that new pump until you pull and inspect the old one. Could be a case of chaffed wires in the pump assembly. If that's the case, you can repair the wires and be back on the road for nothing more than an afternoon in the garage. Mine had the same problem as yours, the pump would run with the engine off but blow the fuse when the engine was running. The wires must not have been touching anything in their own, but engine vibration made them touch some metal and short curcuit. This is what mine looked like when I pulled it out. Bike is an 07 and had about 13k on it at the time. You may still need a replacement pump after all, but don't unwrap the new one until you rule out the famous chaffed wires. If the old pump is salvageable you can return that expensive new one.

Great pic , Listen to him ^^^^^^ very common, that will blow a fuse.

That would be the chaffed wire in the fuel pump..... I believe heat shrink is the accepted solution.

I am intrigued by this dirt cheap aftermarket replacement though. On the product description it claims 20% more flow... Is there some potential for hp gains there??? lol

Interested in this pump too if in fact mine is toast once I pull it out. I did not see (or can't see) a model for 2010.

It would be great if the old pump could be tested while in the bike but I have not come across anything on google.

Here is one , I have not used one., Hopefully it is just a wire short, be positive ,take it out a look at it first then worry about buying one.

I like the KEMSO one, it's made in Japan....

I pulled the fuel pump today. Visually inspected and tested each wire with an ohm meter. Nothing obvious and no resistance on all four wires. While it's out, I plugged it back into the bike and turned on the ignition. I expected a high sounding whir but all I got was some odd sound as if it was trying to turn over and then the fuse blew. Sounds like the pump is toast.

I guess I'll be ordering one from the links provided if there are no other options.

This pump is visually identical - we'll see.

The Kemso 13802 fuel pump is a perfect fit for the 2010 XB12Scg.

Back in business baby!!!
