In the process of removing the fairing, I unhooked the fuel line and a small amount came out, so fuel was reaching the delivery arm. However, when I turned the power on, the fuel pump cycled once but delivered no fuel. I tried capping the line with my finger and didn't feel anything being delivered down the line. I tried this several times, switching the power on and off but still nothing.

Where to go from here?????

The Motronic should be sending a ground signal to the yellow/gray wire of each injector. Hook the plus side of the LED (their polarity makes a difference - if using just simple led then the longer wire is +) up to 12V+. Attach the negative of the LED to the yellow gray wire.

You're referring to the fuel line that goes right to the fuel rail, right?

You can try jumping the fuel pump. Disconnect the fuel tank connector and jump the brown wire to ground and the green/white to 12V+.

I have a two prong plug-in connector hooked to the fuel injector. I don't see any yellow/gray wires. The two prong connector is labeled +/-. I did connect that to the negative and the positive to the battery and got a solid light. No blinking.

On jumping the fuel pump, I don't feel like I know enough to push that. Is it something I can do outside of the gas tank or does it involve getting back into the gas tank to get to the pump itself?????

Might as well test the positive side of the injectors as well while you have the connector off.

I was referring to jumping the fuel pump at the connector, not inside the tank.

There's a group of wires in a black tube that come out at the rear left of the tank and connect somewhere near the rear brake reservoir. It's a four lead connector. Brown, yellow, white and green/white wires.

Thanks...I'll give that a try first....Do I have to disconnect the gas tank to get at the wires?

On testing the fuel injector, do I connect the positive wire to the battery and the negative lead to the positive side of the two pin connector? Also, I assume I test it at the fuel injector, not the wires coming in.....

Thanks for your patience....

Micko,
You never said WHERE you live in Tucson. Did you ever read your PM? (Private Message)

You attach the LED with the - lead to the gray or - wire that feeds each injector. You can do this with a straight pin or slip some 30 or 31 Ga wire in the connector for one of the injectors. The + lead of the LED should go to 12V, preferably at the battery terminal.
If you try to measure the voltage on the injectors, they will ALL look like 12V on both connectors until you crank the engine with the starter motor.

UPDATE: Micko's fuel tank had about 3 gallons of varnish in it, the fuel pump was frozen and the new fuel lines were disintegrating in the disgusting varnish. He has the link for the Techron soak (it may work if there are no solid particles in the pump) and the alternate fuel pump replacement from the IBMWR.

A BMW Tech with a Kaw, I don't know. Just kidding, I think if you're going another route, that's the way to go. You can still stop by if you ever pass through CD'A.

Scott,
Thanks but I still have 3 BMW's and I'll probably always have my K1100LT.

Sat on one yesterday. 2009 with ABS for $11200. Great deal if you ask me. just wish I had the funds for a new bike. My K11LT willhave to serve me for a few more years.
