Replaced Clutch Bike not Starting R1100RT 96 (Help)

[GabeM]

I am just finishing replacing the clutch and was hoping to get the bike going this weekend.

I still have to install the Tupperware and the footrest plates.

 

I dug out the fuel tank from storage and installed it. I marked the one hose with tape stating that it was the upper hose when I was taking it apart, which I connected to the upper line on the fuel distributor and other hose to the lower line.. Connected the two other lower pressure hose and placed about a gallon and half of fuel in the tank.

 

I tried to start the bike and it wound not fire at all. I suspect something with the fuel. Not knowing too much about the fuel system, I tried to check a couple of things, I removed the fuel distributor where in connects to injector, I was expected fuel to pour out, there was a small amount but not much. I hit the starter while the line was disconnected again I was expecting fuel to come streaming out there was none.

 

I wanted to make sure the bike had spark so I removed one of the plugs, hit the starter and observed that there indeed was a spark.

 

I am hoping to get some input on where to go from here. I need to verify that I connected the hoses correctly to the fuel distributor, (the inner most hose connects to upper line on the fuel distributor). Did a miss a wire somewhere the runs fuel pump, fuse, is my fuel pump running at all? I just got most of the bike together and hate to start taking it apart again.

 

Any suggestion would be much appreciated.

first things first, do you hear the fuel pump kick on?

[GabeM]

I checked it this morning, when I toggle the kill switch I hear a slight thump much like the sound of a solenoid and can actually reach under the tank and feel it. I do not hear a spinning or running sound.

 

I left the tank empty for about five months while I waited to get my transmission back. I live in Florida with High Humidity.

I went through the same experience several weeks ago. After R&R the transmission, clutch, and lots of other stuff, and after having my bike sidelined for seven months, I put the tank back on her, held my breath, kicked it over, and ....... nothing. I could hear the fuel pump seem to power up, but it didn't sound "right". After seven months, I wasn't sured I know what "right" sounded like. (Actually, the first thing that happened was an immediate fuel leak all over the engine due to a fuel line that worked loose during the fuel filter change; fixed that).

 

Bottom line is, I'd managed to swap the top and bottom fuel hoses; fixed that and she kicked over.

 

Fyi, here's my post, and the steps I took to test and resolve the problem.

[GabeM]

Is there no visual test to determine if the fuel pump is working correctly. Can I not remove both lines going to the fuel distributor, turn the key to the on position and observe fuel streaming form one of the hoses.

You can hook a fuel pressure gage to the bottom hose using a 'T' fitting. When the pump first cycles (about 2 seconds) the pressure should build to about 3.5 bars had hold this pressure. BTW, the pump should sound like a a whine of a small electric motor. Once the engine is running the pressure shoudl be a constant 3 bars.

 

As the Post above suggest, I'd switch the fuel lines to make sure they are hooked up correctly.

 

It's also possible that one of the hoses blew off the pump or filter when you first turned it on which could cause the problem you are experiencing.

Gabe,

 

First thing,, place your ear to the fuel tank side,, then turn the ign switch ON,, then verify the pump runs for a few seconds.. If no pump noise make sure your kill switch is ON & your kick stand is UP.. If not raise the side stand & try again..

 

If you have pump noise upon key-up,, then pull one of the plastic lines at one of the injectors,, then place a can or jar under the removed line & turn the key on,, you should have a fairly heavy pressurized flow of fuel as the pump comes on.. If you don’t,, then check for improper line connection.. If the pump doesn’t operate AT ALL on initial key-up then look for electrical problems like not hooked up,, blown fuse,, side stand switch problem,, kill switch not hooked up properly (other wire or circuit issues)..

kick the side stand into the up position and try again

[GabeM]

Thanks for the good suggestions.

 

Like I claimed before, I can hear the fuel pump click on, but it makes the sound of a solenoid, something being powered but I can not hear it spin. I removed one of the fuel distributors at the injector site and cycled the key with no fuel stream.

 

I can retire the fuel test at the injector. If it fails switch lines, try again, and if I have no luck I can pull the tank of and examine the fuel pump.

 

The question would be, what would I be looking for.

 

 

Thanks

With the side stand down, the start button does not work. I know I get a spark.

 

Is there a second curcuit that prevents the fuel pump from opperating correctly linked to the side stand.

Gabe, with what you have said above are you SURE both fuel line quick disconnects are Fully seated all the way in & all the way together?/ If those quick disconnects are not fully together they can block fuel flow..

Twisty I am sure what you mean by quick connects. Is that where the fuel distributor connects to the Throttle Bodies/Injectors

Gabe, maybe your bike never had quick disconnect fuel line connectors installed.. If you did (have quick disconnects) they would go between the fuel hoses that exit the fuel tank & the fuel hoses running back to the pressure regulator..

 

If your bike only has hose clamps holding the tank fuel lines to the bike’s fuel lines then you don’t have quick disconnects..

 

If you don’t have quick disconnects then make sure you didn’t plug off those fuel lines with a small plugs & forget to remove them when the hoses were pushed back together (I have seen that done on an automobile once & took most of a day for the guy that did it to find the problem) ..

I had bolts in the lines, and they were removed. I just pulled of the fuel regulator where in meets the TB and cycled the fuel pump, small amount of fuel when disconnected, but No Flow when full pump is cycled.

 

Is this normal or should there be a flow of fuel.

 

Thanks

Gabe, you should have a pretty substantial flow with a very positive pressure (probably like a hard garden hose pressure)..

I guess it is time to drain and pull the tank back off and examine the pump.

[GabeM]

Pulled the fuel pump... Gremlins 1 Owner No score.

 

The screen that filters the fuel before it enters the fuel pump had separated at the lower end. This resulted in the bits of plastic and other foreign material to enter the fuel pump and lodge in the impellor, I was able to remove a few of the pieces with a rheostat however when trying to move the impellor the blades would break off, very brittle.

 

Spent some time switching positive for negative on the pump and applying power in an attempt to break the obstruction free and get the pump to move. No luck finally broke a two more blades trying to turn it.

 

Came to realization I would have to get a new fuel pump since there is no way to service the pump.
