Advice wanted
 
2001, 1150gs
160, 000 km

Bought it last year. Ran perfect, only rode it a couple of times before winter kicked in. On the last short ride, after stopping the bike woulnt start. Turned over then caught just before battery died.
Rode it home.
Next day it wouldn't start and battery drained.
I'd put some fuel stabilizer in it before that last ride.

Spring is here. Over the winter I'd just assumed battery was toast in it.
Bought a new one yesterday.
Bike starts but only with throttle,won't idle.
Sounds like crap, really crap.
Turned it off, drank a few beers instead of riding...

So, I'm looking for some advice for next steps.
Fuel pump certainly jumps to my mind. I'm new to the bike and new to boxers in general and was hoping this scenario sounds familiar to some folks...

Thanks in advance :thumb

throttle cables
 
Make sure your throttle cables are seated properly at both throttle bodies. If one became unseated, easily happens, it will run like you describe.:evil

Define "sounds like crap"

Is it smoking white or black gas? Is it spluttering or what's going on?

Could simply be bad old gas that's been collecting water over winter, if it's too much water in it it might collect in the fuel filter and block it.

I always like to start with the basics first. You've done the battery, which is good. Now I'd drain all the current fuel out and replace it with new and also change the fuel filter.

Then you need to let it run for a while so any trace of old fuel still in the system is used up.

All good advice, thank you.

Now....turn key and I don't hear fuel pump...obviously no longer starts.

Guessing same thing happened last fall when it wouldn't start, I just wasn't listening for the pump to prime.

Double checked connection to tank (wires) was firmly seated. Still nada sound from the pump.

Beemerboneyard sells an aftermarket kit for a reasonable price, any reason I shouldn't order one ?

The crappy sound...like it is not getting enough fuel. Have to keep revs up or it sputters and stalls. Kind of a knocking sounds, sorta kinda...sorry hard to describe in words.

Was hoping clogged fuel filter or something but seeing as I don't hear the pump when I turn the key anymore.....

Check fuses, make sure throttle cables are seated

If you suspect the pump fuses is the most likely culprit, as gsweave suggested.

Does the pump run on 12V? I'm not really sure how easy it is to get to but you could potentially try feeding the pump 12V directly and see if it jumps into life - then you might be able to rule out if it's the pump itself or something eletrical before that.

Be careful though - no sparks around the fuel please :lol3

all good advice...thanks

The pump seems to be intermittent now....sorta rules out fuse I'd think but it's a quick and easy check.

Given pump is intermittent now....even testing it won't tell me much i wouldn't think.

Is the aftermarket pump as good or as reliable as the stock one?

aftermarket is fine.

If pump is really intermittent, grounding or connection issue...

99% chance. Just replaced the battery, this is a common issue.

You've mentioned a few times that your pump doesn't come on for two seconds when you turn the key on. Obviously that's the thing to figure out.

It would help a lot if you had a voltmeter and could measure the switched 12V at the fuel tank connector. Here is a link to a high-level schematic: http://www.mac-pac.org/wp-content/up...agram-V3.1.pdf. 12V is on the green/white wire. The fuel pump also needs a good connection to ground.

If your fuse 6 is good, swap your load relied relay with your fuel pump relay. The pump relay could be bad.

It is also possible that a wire in the tank is intermittent.

You asked about non-oem pumps. They're fine I got mine at Beemer boneyard.

A better title for this thread would be:

Indeed one cable was loose (right side throttle body). A great relief as is sounds like that explains the rough running. Thanks for the photos Jim...a picture says a thousand words :nod

Tank off, double checked wires were intact, still no fuel pump sound when I turn the key. Fuse tested and fine.

Tomorrow I'll yank fuel pump out and test it standalone.

My gut says it's toast but worth checking. The sporadic work, no work is something I've experienced on other bikes....

The help and tips are greatly appreciated. This is my first fuel injected bike in a few years. I switched back after some fun years riding orange. Reliability was one of the driving forces...sadly my budget didn't allow for a new bike so I went with a non canbus, high mileage one in hopes of ease of maintenance.

Cheers
Ted

Did you swap the relays?
