Hi all
I hope that the summer provided lots of opportunities to hit the road (no pun intended). The summer here in south east England was a non event. I was all set to go to France for a few days and thought that I would service the brakes. The day before I cleaned her. Now she wont start...... It began with a strange deep vibrating sound then the fuel pump stopped priming. I have removed it and wired it up to prove that it works. When I switch on the fuel gauge works. but still no sound from the tank. I did tidy the wiring to the tank but only to re route it as the last owner messed it up. Can anyone give me a steer? So much for four days in France.

Cheers everyone

Tony

The fuel pump is grounded at the fuel level sensor, check that connection.

I had a bad connection in the fuel gauge sender unit which would not allow the fuel pump to operate. A new (used) sender unit fixed the issue.

Check the connector to the fuel gauge sender unit (the plug under the right hand side panel), the one that you have to disconnect to remove the fuel tank, it is often the cause of the bad connection.

Mine however was actually in the molded white plug directly under the tank. As it was a sealed unit, there was no way to repair, just had to replace the whole unit. All fixed for now...

A rather lengthy thread of my issues with this devil...

I just had an experience this week. Happened twice. Same problem had guages but no pump. Bypassed sidestand s witch, pump worked fine. I had run 120 miles in the rain the weekend before.So try bypassing your switch and see what happens.

Update, today I had another "no fuel pump" when turning on the key. Even with the sidestand switch jumpered out, so I think I can rule that out as the culpret.
I reseated the plug on the top of the motronic module and the pump fired right off.
time will tell now......

The tank connector is a common point of failure. Replace it thusly:

I bet that will cure it. It worked for me.

So how do you unhook that when you need to remove the tank?

I prefer something a little more "plug and play".

This is a slick four wire connector I got from Jim at Eastern Beaver after I demolished my factory connector (for no good reason, it turns out! Twisted Evil

).

Unfortunately due to the age of my bike and issues I've had with it (and farklizing!) I am frequently removing my tank.

Nice, neat and almost factory. I love the Eastern Beaver stuff. I have the headlight relay kit, two driving light kits, the heated grip relay kit and this plug.

If had any more Beaver on my bike, my wife would get jealous!

Alway the best quality and Jim is a real human that will reply to emails and is an electronic genius, in my humble opinion.

Dave, I agree with Malcolm.
Choc Block (so named, coz when I was a lad it wasn't plastic, it was Bakelite & looked like a chocolate bar) is a prove it, not a permanent repair. If that is all you have, for reliabilities sake, consider smothering it in Vaseline (petroleum jelly) or my favourite, spray chain grease to protect from the future Derbyshire weather.

Malcolm,
Don't go worrying about arcing wires, to explode, one needs petrol & air in the ratio of 1:17 ish. As it is submerged, there is no air.
Consider also, the fuel pump is a DC brush motor which arcs better than any duff connection. How many K's, F's & R's would be a smouldering heap at the roadside if it could ignite & would you want your balls to be that close to such a potential fireball Question

Malcolm - I don't think you'd have to open the cap - I'm sure as the fuel level goes down, the space in the tank that formerly had gas in it is filled with air and gas fumes. I could be wrong...

Hi Guys Still no luck although, I have yet to change to the tank connector plug. I have stripped out the tank and each component works on the bench. So, the plug is next. Maybe t should have been first Embarassed

.

One other thing although not related. I have come across a part of the loom under the seat on the left. From it comes two wires the first is quite thin with a female spade connector and the other is thicker with a simple washer type connector. both are live.

Can anyone tell me where they should attached. ...

Eventually I will get to the bottom of this bike!!

Thanks in anticipation.

Tony

Tony - when you reference wires, it always helps to say what colour/s they are.

Hi Jim

Thanks for the prompt reply....So stupid of me....

There are three wire going into the washer type connector, they are all brown. The other smaller wire is coming from the first connector and has a female spade connector at the end, this is black.

I hope that clarifies a query that I made difficult in the first place!!

Cheers

Tony

That is the diagnostic connector for ABS and Motronic.

I'm pretty sure brown is ground.

Many wires have a secondary color stripe - it helps to know what color the stripe is too when you're trying to figure out what a wire does.

Do you have a schematic? I think there's a link to one in one of the tech stickies.
