1100 EVO wires pulled out from back of fuel pump plug

[slopjockey]

At the propped up fuel tank stage, of battery replacement on my 1100 EVO â€"the prop slipped and the tank fell to the side cleanly pulling (i.e. soldered pins on the ends of the wires remain in place) from the back of the fuel pump connector/plug. As the ports on the plug are numbered 1 to 4; and the wires are colored red white blue, and black… can anyone tell me the correct order to replace the wires in the plug?

As a couple of the little yellowish, accordion type grommets are damaged… I'm hoping that I can push the pins through and silicone them in place.

Any suggestions would be appreciated.

Thanks guys;

Greg


ps  it's the 16023791B pump that I think is common to 696, 796 and 1100 models.

SuzyJ has an excellent post in the tutorial section which details what the connector types are, which might help if you need to buy new grommets or pins. I don't have a fuel injected bike so I don't know which wire goes where, but if you can find a wiring diagram, it usually shows the connectors with numbered pins and the color of the wires also indicated. Good luck!

Thanks for the heads-up to the most excellent SUZYJ tutorial. My connector is there alright. I'll try to find A wiring diagram.

There is a wiring diagram in the back of the owner's manual.  No owner's manual?  Go here:  http://www.ducati.com/services/maintenance/index.do  Better place anyway, since you can use the zoom feature.

Thanks Howie I'll give it a shot when I get off work.

This is going to be another learning experience for me.

I looked at the schematic and did not see any wires colored red, white, or blue at the pump connector. The way I read it (in order of connector pin positions as depicted): 4 is Bk, 3 is P/Y, 1 is Bn/W, 2 is Bk.

I know propping the tank up on an evo is more convenient than fiddling with the fuel lines, but it is risky. The tank is not hinged, therefore there is nothing holding it in place laterally. The propensity for it to fall to either side is mainly relative to the width of the prop used at the rear. Caveat mechanicus.

Thanks for checking oldndumb. Like you, I am seasoned and slow; which probably accounts for getting myself into this predicament. Essentially your observations correspond with mine for the wiring harness side of the diagram. I'm guessing the schematic is not detailed enough to show the fuel pump side of the equation which is definitely red white blue black. In positions 4&2 I have black (but with a green stripe). In number 1 Brown/w. In number three I noted, before I closed it up â€" orange/ yellow. I'd say three out of four with the right colors/ positions is close enough to be a match.

Because it looked like it was possible that the wires pulled out of the plug in the order that they were in it â€" I just tried to push them back in. Nada.

So then I flipped the plug 180°, And put them back in. Voila-I got what seems to be the fuel pump priming sound and also the low fuel light on the dash is lit.

It still didn't start; but I didn't try very hard â€" I thought I would check on the net to see what I could come up with.

Anyways thanks again for trying.

Sounds like you are on your way to sorting it out on your own. I found this pic of a pump assembly which was for sale. Don't know how much it will help, but you can see where a few of the wires go.

Wow! Cool! Thanks! With that pic, and the schematic, that's got to be the fuel pump side of the equation solved

Sorry for the thread resurrection, but does anyone have a clear picture of the wiring into the plug?

I've found myself in a similar predicament...
