R1150RT Engine died while riding

I was riding home today in 65 degree sunny weather going down the interstate. My 2002 R1150RT was performing great. All of a sudden I lost power. Like I ran out of gas. It will not start. When I turn the key on all the lights come on, I hear the normal sounds but it will not start.

 

Anyone have an idea where to start?

 

Could it be alternator belt? Hall sensor?

Down to basic testing mate !

If the starter cranks your motor over and she no fire up :

 

- Do you have a spark?

- Do you have gas at the injectors?

 

Then backwards systems check on from there.......sorry, nothing easier than that :(.

Start with easy, move progressively to harder. If the engine cranks and does not start, First, check your fuses (#5, I believe). Then move on to spark and fuel.

 

If there is no spark, the Hall sensor is a prime place to start, as is testing your coil. You only have one, and it fires both cylinders every time. If you get that far, and haven't found it, come back here and you will get a bunch more suggestions. Good Luck!

When you turn the key on you should hear th fuel pump run for a few seconds. If you hear nothing it could be the fuel pump or fuel pump relay. I believe the horn relay can be swapped with the FP relay for a test.

Or it could be the connector/plug.

Thanks for all the suggestions. I was so frustrated getting the bike home that I did no troubleshooting before making this post. The starter does turn the engine over and I hear the fuel pump run when I turn the key on. I am going to check for spark and fuel this weekend. Will let you know what I find out. I'm sure I'll need more help after doing the basics.

Its Fixed!

 

I checked spark and it was OK. Next I pulled an injector out and checked for fuel. No fuel was coming out. I happened to look at the two quick disconnects for the fuel lines and noticed one of them had worked itself loose. About a month ago I had the tank off and I probably did not get the quick disconnect connected back securely. So it took a month to work itself loose.

Also check the side stand switch. If that is faulty/tripped that will stop the motor. I have experienced a sticky/slow side stand switch on a different machine.

 

Hope that helps.

I was gonna say that. Happened to my friend's 02 RT last year.

 

During the process of tearing the bike apart on the side of the road and trying to make it run, MISSING the loose connector, one of the lines inside the fuel tank blew off...

 

So once the loose connector was found, it still wouldn't run. Pulled the fuel pump plate, put the line back on, bike fired right up.

 

Just posting this here in case somebody else searches up on it.

Oddly enough, I had the same issue as Paul the other day. I was undoing the external fuel filter mod and putting the filter back inside the tank. When I got all the lines and connectors back together I started the bike to make sure it ran. Initially, it ran poorly and backfired, so the first thing I checked was whether the throttle cable had pulled out of the barrel on the right TB, which it had. Put it back, bike ran fine. Bolted the tank into place, put all the tupperware back on, tried to start the bike, no start. :mad:

 

What I did notice was that the sound of the fuel pump when I turned the key on was louder and much higher pitched, as if the fuel flow was blocked. So off came the tupperware, and the tank to look for pinched lines, hoping the problem wasn't inside the tank. As it turned out, one of the fuel line disconnects was disconnected about 1/4 inch, just enough to shut off the fuel flow but not enough to be easily visible. Apparently when I reconnected them initially, I didn't get one connector quite together, and when I dropped the tank into place and zip-tied the fuel lines into place, the connector pulled apart.

Why????

 

Because I had the fuel filter mounted under the black side panel on the right side, in that triangle of the frame where the remote reservoir for the stock shock is. Then I bought some fancy Wilbers shocks from Ron, which have the remote compression and preload reservoirs. The fuel filter and the preload reservoir wanted to occupy the same space. I tried to squeeze the preload reservoir in, but where I could squeeze it in around the fuel filter, the swingarm had enough travel to hit the banjo bolt on the end of the reservoir and shatter it. :mad:

 

So to be able to put the (repaired) preload reservoir where it wouldn't get whacked by the swingarm, I had to move the external fuel filter. There was no other good spot near where it was. To mount it under the intake tube as shown on the IBMWR tech pages, you need to use a smaller diameter filter than the stock one (the stocker won't fit under the body panel). I wasn't comfortable with substituting a smaller filter, I couldn't get good information on the tech specs of any substitutes, and anyway I didn't like the way the fuel lines were starting to show not-so-tiny cracks at the bends that are necessary to do this mod. So I decided the simplest solution would be to put the filter back in the tank. (I have two tanks - the original one and the current one modified with a fitting for a fuel cell - and returning to stock also makes it possible to interchange the two tanks).

 

I have to say, putting the fuel filter back inside the tank, getting it together and finding that the fuel cell fitting had come loose, taking it apart to tighten the fitting, putting it back together again, realizing I had left the o-ring off, taking it apart, putting it back together . . . :eek: I remember now why I wanted to move the fuel filter outside the tank.
