03 R1150rs No Go

[Labdaddy]

Hello,
My RS ran great on the way to work a couple of days Ago. After work, turned over but no start. Has spark. Today I pulled the fuel pump. It works. put it all back together and no fuel to plugs. Dry as bones. I can hear the pump working. Why is fuel not getting to the TBs? Im stumped and quite frustrated. Any ideas are greatly appreciated.
Thanks,
John:dunno:

The injectors are not being activated. Fuel flows like a river to the injectors. Could this be Hall sensor?

Sounds like it may well be the hall sensor. Sudden, and fatal. Check advrider.com for support with your troubleshooting...loads of 1150 oil heads over there. Good luck...

HES failure is rare on the 1150. I would suspect you blew the fuel line off inside the tank.
Pull the outside fuel lines loose and turn the bike on (you will have to hold the quick disconnect open if you have them). Since the pump runs at 'key on', you should have fuel shooting out of the fuel lines. If not, you have lost the hose inside the tank.

Had this happen on my RS. Some fuel will come out of the fuel lines with gravity. You are looking for a noticeable gusher with the fuel pump turned on. Have a jar to catch the fuel in. And of course no flames near by.

Is it? I thought it was the same unit as the 1100?
If it was the HES though, there'd be no spark I would have thought.

[flars]

Physically, the 1100 and 1150 HES plates look the same, but it is thought that the HES wire on the 1150 is different from that on the 1100. That is why the replacement parts seem to be more reliable.
When the HES fails, you can potentially still have both spark and fuel being delivered. The problem is that, with the wires shorting against each other, the signals arrive at the wrong time, so the bike doesn't run. Of course, sometimes you won't get a fuel or spark signal at all - it depends on which wires are shorting together. This is also the reason that testing the HES is often a waste of time, since they will ofttimes test fine - I don't know why that is true, but it has happened many times. The main HES failure symptoms besides not running, is the tach bouncing when you try to start it. Again, not always, but frequently.
Testing for fuel at key on will speak volumes.

All good info - thanks.

Just bought a R1100 RS SE thats been stood for 2 yrs,
got very similar symptoms as in got spark, new fuel & had injectors cleaned but still it won`t fire or cough, plugs are bone dry even with choke on & throttle wide open. Could the HES be at fault on mine? Being new to all this any help would be appreciated. The bike is a 99/00 model.

If the plugs are dry and have a strong spark the problem is likely to be the fuelling. If you remove each injector at a time then crank the engine you should see fuel squirt from the injector if the fuelling is working. (Aim the injector into a suitable receptacle to catch the fuel, checking each one separately). In your case you'll probably find that no fuel is squirted. Since the bike has been stood for a fair while it is quite possible that the fuel filter is clogged, either the mesh one on the suction side or the metal cannister one on the delivery side. This assumes that you can hear the fuel pump whirr when you switch on the ignition; if it doesn't there's a fault with the pump or its circuitry.

[SBH]

Thanks for the reply, just a deathly silence when I turn the ignition on so it`s looking like the pump.

To SHB -
Make sure the electrical plug on the right side of the fuel tank is plugged in. Also check to see if you are getting power to the plug when you turn the bike on - you could have a bad fuel pump fuse or bad contacts for the fuse, or the relay.
If there is no power to the pump connector, replace the fuse - they can look good, but not be.
If you have power at the connector, check for power at the output side of the connector to ensure no broken wires there.
If you have power there, you will have to pull the pump to check it directly with 12 volts.

Hi flars, checked all the fuses, relays etc & all seemed in order and have now pulled the pump / filter / float assembly out. Wired the pump direct to the battery & nothing so I`m assuming the old fuel has gummed the impeller up where it`s been stood. Thanks for the tips, will source another pump & hopefully report some good news !

[SBH]

Ok, got the used pump in & it fired straight up. Only thing now is .. got about 5L of fuel in the tank but nothing showing on the fuel guage (though the light is on). Just wondering if I`ve positioned the pump / filter / sender plate correctly or it`s out by a bolt hole either way (should have paid more attention taking it apart !) Can anyone tell me what position the small flat edge on the plate should be, mine`s about the 9 o clock position.

SBH,
I started the fuel thread. Mine was fixed by shooting carb cleaner in the injectors and leaving them for two days. Came out, turned it over and fuel squished like crazy. Plugged them in and it started right up. Been fine since. Now like you though, I have no fuel gauge. I put my plate back in the same position, as I marked it prior to removal. Did you figure yours out? Any ideas would be appreciated.
Thanks, John

[SBH]

Hi Labdaddy, I`d located the pump plate in the correct position & put back in the fuel I`d drained out (about 5 ltr ish). This amount had put the fuel light out but not registered on the guage. After a trip to the petrol stn & £10 in the tank, it finally gave me a reading on the guage.

Guess it looked like a lot of fuel I put in to start with when it wasn`t enough to start lifting the sender, and that got me flapping. Hope yours turns out to be something as simple.

[Labdaddy]

Hi SBH,
Its been months, been using trip meter. I will take off the Tupperware and tank this winter and remove pump then reassemble this winter. I have filed the tank many times since. I apparently buggered up the mechanism or disconnected a wire in the process of reassembly. To many bikes and not enough time.:D What a shame, eh? Thanks for your help.

Or trapped the float with one of the overflow hoses inside the tank. You can probably figure out how I might know this ...

Check the connector block from the fuel pump, the guage uses the same one. I had my fuel lines replaced at a dealer recently, and when I rode it away, the fuel guage wasn't working. I took it back, and the mechanic found that there was a bit of corrosion in the connector block, he cleaned it up, and it solved the problem.

[Labdaddy]

Thanks guys, I will check these things. I was just so happy it was running, I figured I would het to the gauge later. I took it apart and back together several times and wasn't excited about doing it again. Thanks again,
John

Hey everyone, while we're on the subject of fuel tanks, what's the type of fuel hose that is needed for the overflow hoses that run inside the tank? Thanks :)
