Total fuel pump failure

Hi folks,
Yes my '08 TE 510 has roughly 3,500 miles on it, bought it in March '08 and has run perfect.

While deep in Las Padres Natl. Forest, bam fuel pump failure. There were pre existing symptoms: Bike was running very rich and jerky on the very bottom, once you gassed it ever so slightly it cleaned up perfectly. Very hard starting with a pop and a stall of the starter motor at TDC every third or forth revolution. Sounds like timing is out. Checked valve timing and is correct.

Thought I could get out of my jam with a fuse change, fuses all good. Well the long walk out of the forest began. Met up with 2 hunters after 7 mile hike, they drove me out to my truck.

Pulled pump motor and will not prime or run when given power.

Bendbiker has a great thread that Im following up on. But if anyone else has had anything similar give me a shout.

The entire assembly from Husky is $578 and so far no hope in just replacing the pump itself.

Thanks again
Jim.

You might give George (1 714 540-2920 a call on this. Although the fix he's working on involves the plastic fitting he may have some insight on your problem and know if there's a fix. Plus he's always talking to the racers like Ty Davis and may have some factory information available.

Thanks glangston will do.
Although these pumps are sealed units, don't think there is a fix on these guys besides buying new. Just trying to minimize the $ damage.

Well if you mean putting the fuel pump assembly into another tank and trying it? No.
But I know putting another tank on with another assembly WOULD fix it.

Jim.

Did not see that but I'll look it up in classified.

Thanks Dean
C-ya Jim.

Sorry to hear of your trouble. I'm confused. You say "fuel pump failure", and then you say "no juice what so ever to the pump." Which is correct?

Sorry my mistake, the pump is dead when putting power to the posts. Does not prime. I'll edit my thread.

Jim

Just FYI,

There is a cut off inside that little pump, so it wont run if its not right side up. Make sure you are holding it in the correct position.
Just sayin.

The Husky fuel pumps are VERY high pressure. Much higher than most others. So its not so easy to just change over to another system.

Let us know how it goes.

7 miles....barefoot or booties or boots? Yikes thats a long ways.

Glad you got the bike out.

don't throw it away, check the relay first, I had all of your symptoms , even the "dead" pump, turned out to be a failed relay, replaced with aftermarket one from the local sparky shop,
all is good.

pump

that pump from summit is for external use only. not for in a tank.. used to use a pump about the size of the husky one in formula atlantic, used a VW and sometime a GM pump from a metro. i would stop by a dealer with the old one and compaare the size and electical connections. there should be info from the dealer on fuel pressure required and amp requirements...

Good point Mike with the position of the pump.

Well, I knocked on the side of the pump with handle of a screwdriver and what do you know? Pump kicks on normally with key or kickstarter. Have not ran bike yet but, so far 20 or so turns of the key it still works.

I think it was bendbiker that did the same thing with his, but it began to fail again later.

Thanks Cranky I will check out the relay.

Boots and riding gear were my hiking apparel that day. About 80 degrees, not too bad.

The saga goes on:

New findings in the fuel pump failure problem. I took out the fuel filter which is mounted in tank just after fuel pump motor. Put fresh gas into filter, out came an ugly, black liquid resembling gas after cleaning your air filter.

At some point my TE took some bad gas from the pump and when it happened I noticed it turned everything black. I dumped it out immediately. It left a black film inside the white IMS tank and everywhere inside fuel pump assembly, even the fine mesh fuel pick-up's were very dirty.

I think its obvious this bad gas has done bad things to my fuel pump.

Will fire it up tomorrow and report my results.

ouch! That sucks JimO, Did you get it back to normal yet?

Good luck!

George was right about the gas being crappy, just didn't know how right.

Interested in your results.

Jim, sorry for a long delay - I've been on the street bikes in Colorado and Canada.

Anyway, after three times of opening the fuel pump motor by prying up the lip and looking for the trouble and cleaning the commutator and brushes, the motor would run for for 5 or 10 restarts then the same problem. Tapping the side of the motor with the key on causes the motor to spin. Also, no luck buying just the pump motor, so had to buy the whole assembly for appx $600. That is a shame on Hushy/BMW. The 09 pumps are made in China as compared to the Check Republic. Maybe the new ones are better! They look the same though. Some people might have faulty connections and some others might have faulty relays - all possible. But for sure some/several have pump motor faults. I'd like to see Husky dealers to pressure BMW to refund our costs. One year or less on a electric fuel pump with minor hours compared to car or street bike fuel pumps is a shame.

Thanks bendbiker for reply.

No I have'nt opened up the pump motor yet but my guess is what caused my failure was possibly bad gas. Most likely two different pump gasses not getting along together in the tank. Yes, George is right about bad gas out there.

It definitely is a shame that Husky does not offer these individual components of the fuel injection system for sale. Yes your vehicle fuel pumps last for years, you'd not expect a new 2008 state of the art motorcycle to have a pump motor problem.

Still I cant force myself to pry apart that pump motor, for sure it will booger the crap out of it. When it stops spinning I'm sure I will dig into it. So far it still works after banging on it a bit.
C ya, Jim
