Tried to start it again and no luck. No noise from the pump either, flipped the tank up to listen and couldn't hear a thing. Is that indicative of a failed pump or can that also be due to the filter? Ill try and replace those relays at the same time as the filter. They're 12v 20a relays right?

Usually it's the relay.
There's two there, try switching them to see if you can get the pump to go that way.
You can't ride it that way, but it's an easy test...

You may have a wiring issue.
Possibly external, check the connector, make sure it's securely connected.
You can disconnect/reconnect a couple times to see if it'll scrub the contacts enough to get it working (not likely, but free).

There have been failures of the wiring that goes into the tank, thankfully there's now a relatively inexpensive fix.
I'm pretty sure this is the correct unit for your bike, *if* that's the issue.

You can also temporarily jump terminals 87 and 30 at the fuel pump relay.  If the pump now runs, replace the relay.  If not, check the brown/white wire at the connector to the fuel pump.  Got 12V?  You probably need that Ca Cycleworks kit Speeddog suggested.

I'm not sure what those relays points are, is that the quick disconnect wire running into the tank? For $6 I figure it's worth trying to swap the relay (the bike is stuck at a friends house so quick checks like that make less of a pain to his family). Is it the left or right relay (I'm thinking of the two relays on the left hand side of the battery if you're standing at the back of the bike).

Thanks for all your help guys, I appreciate it!

Ok, so I tried to start it before swapping the relay and I heard the fuel pump start and it the bike fired up instantly. Do dying/faulty relays act that way? Swapped the new relay in and it started as well, though it was idling a little rough. Going to have to get a different relay; the part number provided was for a 30a, not a 20.

Howie

A relay rated higher than needed is fine.  Keep the 30.  The terminal numbers are the connector that the relay goes into.  The numbers should be on the relay itself, if not I will tell you how to figure it out.

ANedelka

Ok I'll take a look later. Does the fact that the old relay started the pump again indicate that the relay might be a less a fault than a wiring issue?

Howie

Both can be intermittent, so I can't say.  I would suggest searching the board for threads on the wiring issue, there are some really good posts and photos.  Some nice DIY repairs too, but I would still go with the Ca Cycleworks kit.

Ok perfect thanks howie! I picked up the fuel filter today and ill order that wiring kit as well. Hopefully those fix the problem.

I only wished that this kit was available before i repaired mine. Well worth the money!
