  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

2010 TE450 with 22 miles, fuel pump quit working

I took it for a ride, got some gas, rode back home, shut it off, messed around, went to start it, it started but died, seemed to run out of gas, I reset the key, did not get fuel pump whirring, key off and on many times, no fuel pump whir.

I almost starting tearing into it, turned the key on, fuel pump whirred, bike started.

Has anyone had this happen to their bike?

Thanks
 
Battery connex are tight.

Fuses are seated and intact.

Anybody know what the fuses are connected to on the TE450? Two 15A and one 20A.

I just had a fuel pump fuse incident. I wash my bike after every ride. When the fuel pump wouldn't prime I thought the worst. Turns out the fuse was corroded. Probably from too much washing :)

Test and/or replace ALL of the fuses, don't just glance at them and think they are OK. Factory fuses are cheap and are known to CRACK (internally the blade will crack/separate), if you look very closely you can see it but it's not something you would normally see.

I'm guessing that's your issue, mine did the same thing and it was the fuse. They use standard mini type fuses, same as autos.

Which fuse is it?
 
Have you tried the kicker or bump starting it? Are you absolutely sure the battery has a sufficient charge? Can you jump it with another battery?

Battery is charged. E start works. Fuel pump was not whirring/priming. Didn't try kicking or bumping because bike was out of gas at the FI. Fuel pump started working after 20 minutes and bike started right up when gas was made available.
 
Can someone look and see how your Fall sensor (also called Tilt sensor) is affixed on your right side, near the 3 fuses. My Fall Sensor was just hanging down into the bottom of my airbox, by the wires.

I believe the Fall sensor is wired to stop the fuel pump in the event of a fall, killing the bike and preventing fuel from being pumped everywhere in case of a damaged fuel system.

Its attached exactly how it is shown in that pic, if it was hanging down into the airbox that could be the culprit, you are correct on the operation of the sensor. Have you replaced the fuses yet? :excuseme:

The fuse (the "P" fuse is the fuse that is connected to the fuel Pump) tests fine and is not corroded. Since this problem was short-lived (the fuel pump primes fine now) I am not suspecting the fuse.

My fall sensor looks totally different than the pic. I have no bolted bracket to be seen anywhere near here. I suppose I will orient the sensor near as I can to the picture and zip tie it into position and go with it.

Funny thing, I have placed the fall sensor in numerous, different positions since I found it hanging in the airbox, and the fuel pump primes up fine, the fall sensor seems to have "lost its bearings" and is no longer signaling a fall.

When did they start putting on the tilt sensors on the TEs? They were only on the SMs....
 
I don't believe you have a fall sensor on your te. That capped off connector centered in the pic looks a lot like the O2 sensor lead with a jumper cap installed. However, that would normally be up under the tank so it may be something different. Do you have the power up kit installed on the bike? (O2 sensor removed with jumper installed, cat removed)

I think you're right about the cap, I think the TE has the lead for the fall sensor, but the black cap shunts it off. That's why there's no brackets and no mounting bolts for it. I'll bet all other 2010 TE450s ahve what I have under there.

My wire colors are the same as my diagram for the fall sensor, I do have the PowerUp, and I do have the cap plug where the 02 sensor went. Thanks.
 
Come to think of it, my 08 te 510 had a dangler like that in the airbox! Never really thought about it till now. Was probably for the fall sensor if in SM trim.

One other thing that could fail is your kill switch near the right thumb. Either it could be intermittent or have faulty/damaged wiring somewhere along its path. If you can't isolate the issue, you'll end up removing the tank and inspecting the wiring most likely. That will also allow you to check ALL connectors for security and even remove and inspect the fuel pump assembly if needed. I hate intermittent issues like that :banghead:

Maybe, or on my '08 SM510 I have a dangling turn signal relay on the LHS in the airbox area. I tried to mount it on a bracket as shown in the owner's manual but it is not even close to fitting on the bracket so I'm guessing mine isn't the only one with a dangling turn signal relay.
 
Ah, yeah looks like that is a cap for the plug where the fall sensor would be on an SMR.

Just replace those fuses, the factory ones ARE weak and can crack, a small fracture is hard to see and can cause the fuel pump to sporadically work.
