More fuel pump issues?

[Laitch]

Maybe members more experienced in electrical troubleshooting shortcuts—like Robert or Inge—will chime in here. I'd be plodding along using a wiring diagram to check current input at the fuel pump fuse, output from the fuel pump relay, proper switch function and so on.

Sometimes, Rami, you just have to pay your dues by poring over the millions of words in the "Fuel System" posts in the Child Board section of the workshop using the search box and then take a long nap.

It's also more effective to start a separate post with your personal bike's problem to make it easier for respondents to get to the point for you.

Lastly, but not leastly, following this diagnostic schematic will help. Follow red lines if the answer is "no"; green lines if the answer is "yes". Your bike model differs but the principles are similar.

Hope you don't mind that I'm borrowing the thread, but I can relate right now.

My fuel pump won't run. It doesen't prime on ignition and bike won't start. Is there a quick way to try and hot wire the pump so I can know for sure if I need a replacement? 1996 k11lt

I've no idea how different your bike is to mine, but did you read the whole of the thread? I showed how I checked to see if I had a voltage at the pump, then I measured it's resistance. Would have been easy to hot wire to check the pump worked if I had not found that the current was already reaching the pump.

With the '96 1100LT, the pump should prime for about 3 seconds when the key switch is turned on.
I had troubles with my '95 and it ended up being the motronic multi-pin plug. The contacts got dirty and wouldn't carry enough current to operate the fuel pump relay.
Pull your plug, clean it with some De-oxit(electrical contact cleaner) or similar that you might have available and re-seat it and see what happens.
Cycle your kill switch as well. They get finicky with age too.....

And check the sidestand switch circuit.

Thanks for the input, I pulled the pump from the tank last night. Tried to feed it with 12v and it didn't make a sound. The gauze bag was not sealed and the bottom of the pump looked kind of nasty. So my guess is that i siezed?

And check the sidestand switch circuit.

I did not know about this switch. One question though, will the side stand switch only kill the fuel pump? Because my bike will run on starter gas.

Unless someone has by-passed it, the side stand switch should also stop the ignition circuits as well, same as the handle bar kill switch.

Great, so I can rule out any of those and continue with my hunt for a replacement pump.

Ramnaan try reversing the polarity of the wires a couple of times it will sometimes dislodge the crud that is jamming it. Short bursts alternating back and forth.
