Long story short, swapped the salvage title frame to a clean title frame on my 2005 buell XB12s. Project started a looong time ago but now I am wrapping this project up. Got everything together but it wont start. The engine turns over, but I cannot hear the fuel pump come on. Everything seems connected and all fuses look good. Could it be the Bank Angle Sensor ? | ||

Check the relays (on left side)...with the ignition off switch them and turn on the ignition. That is if one of the two is not bad. | ||

Do you know wich relay and/or fuse the fuel pump runs off of? It doesnt say anywhere on the fusebox. I have confirmed spark btw, just no fuel. I jumped the BAS sensor green wire with the black as per recommendation from harley forum and no dice. Could I have a bad fuel pump? The bike ran before the frame swap. Is there a way to test a fuel pump w/o removing it? There is four wires leading to it so I dont dont know nwich ones need to be hooked up to 12v to test the pump. | ||
| Jfman |
I should mention that the bike has sat w/o any fuel for 3 years. Zero fuel, none, not a drop. I put the bike together then I didnt mess with it until a few weeks ago. | ||

Turn the key on, then toggle the kill switch to run, does the check engine light come on for a few seconds? If yes, you have a fuel pump issue (not connected?), but if it doesn't come on, you have an ECM issue (no power?) | ||
| Jfman |
Thanks for you help froggy. Yes the check engine light does come on for a few seconds. If the ecm was bad I would not have spark anyway... right? What relay and fuse does the pump run off of? None of them say fuel on them. | ||
| Froggy |
I'm not an expert when it comes to reading wiring diagrams, hopefully this can help:  | ||
| Jfman |
So grey (power) and black (ground)? .... right ? | ||
| Mlink |
The fuel pump is in-line with the ignition relay: top left = ignition relay top right = start relay bottom left = key relay bottom right = empty (keep spare here) | ||
| Jfman |
So if I have spark then I can rule out the relay... Bought a test light now gonna look to see if power makes it to the pump. | ||
| Jfman |
Fuel pump is getting power and ground is good. Oh this is gonna suck....... Has anyone ever had any luck taping the assembly with a hammer to get it to run again ?? Nown that I put two gallons of fuel in this bike what is the best way to remove it w/o making a mess? | ||

I suggest letting it sit for a while with the fresh gas in there. Perhaps it will loosen up. | ||

The power is the Grey wire but the ground for the pump itself is provided via the ECM (that's how the pump is turned on & off). The ground is used for the low-fuel sensor. If you carefully hooked up +12 volts to the grey and the -12v to the brown/yellow wire you should be able to test the pump. They shouldn't be run dry BTW so make test a really short one. You might be lucky and have a wiring issue between the ECM and fuel pump but it is probably more likely to be the pump itself gummed up I would guess. There was a guy here in Australia who recently had a similar issue with a Buell that had been sitting for a very long time. He actually managed to free the pump up after pulling it out - he also had sticky fuel injectors that freed up with some carby cleaner. In the US you can readily purchase the Walbro 521 fuel pumps (or several other equivalent ones) for around the $100 mark so worst case you would need to pull the pump and with a new pump, O-rings and filters you would be less than half the cost of a whole assembly. | ||

If you have ECMSpy you can tell the fuel pump to run in the diagnostics section. | ||

Rays: I hooked up power directly to the wires leading to the pump and nada, no contact. I thought a bad pump made the fuse blow or the wires melt but no in this case, I have no contact. I remember buying a new fuel pump sock filter back 3 years ago for it when I swapped the pump to the new frame. Maybe somehow a wire got disconnected.... ? I drained the fuel and in the funnel's screen there was a little bit of brownish/rusty goop... Gonna pull the pump tomorrow if I feel like it. How high ddoes the bike have to go for the swinger to make room fot the pump? Being in the city, I dont have access to much of anything as far as lifts or jacks go.

How certain is the Walbro 521 for a replacement part? I have a spare pump I need to rebuild. http://www.summitracing.com/parts/VPN-521-1/ http://www.fuel-pumps.net/521.html http://www.jdsperformance.com/index.asp?initemuid= 794&fcmd=item&inmake=0 | ||

Also said to be the same as 2003 Mustang with v6 which you can normally find at your local auto store for around $100 http://www.autozone.com/autozone/parts/Airtex-Mast er-Fuel-Pump/_/N-8vcz2?itemIdentifier=820626_0_0_ Part Number: E2366 EDIT----- This is not the correct pump for the older style cycles, might work for newer style (08+) (Message edited by Greg_E on June 17, 2012) | ||

There is a risk that the soldering on the fuel pump is bad. I had some dirt in my tank that caused a galvanic element that took away all the soldering at the connections on the fuel pump. I took the pump out and re soldered the connection and after that it worked! | ||

I just pulled my spare apart to start the rebuild... It has a big stylized W stamped into it as well as the name Walbro and 521. Also a number 23004-2B Mad in USA | ||

Here is a cross reference for different fuel pumps: http://www.fuelpumps.com/page.html?id=2 Searching through I get the following matches: AC/Delco EP274 Delphi 25337782 Delphi FE0052 Ford E5ZZ-9A407-A GM 25116975 Hella H75010041 Punching in their search engine the Walbro 521 is used in 1985-1986 Mustang 6 cylinder 3.8Liter... This crosses to Airtex E2061 which you can get at many auto parts stores. The strainer looks like it might be an Autozone FS220 and the filter is either an FF3419DL or FF3330DL. Total will be around $125 plus tax. (Message edited by Greg_E on June 18, 2012) | ||
| Greg_e |
E2061 pump and FF3330DL filter fit correctly, need to order a strainer. | ||
| Rays |
Greg, the AC/ Delco is a EP274 on that cross-reference list. The only reason I twigged to the typo is that I recently bought one on the US eBay to replace a supposed E2061 I bought from Autozone while on a recent business trip. Word of warning - if you get E2016 from Autozone and you are about to drive to the Boston airport and fly back to Australia - make sure you open the box and check what is in it.  | ||
| Greg_e |
Thanks, changed it. My E2061 is installed in the assembly waiting for strainer and O rings to arrive so I'm pretty sure it is the correct part. | ||
| Jfman |
I cannot get the pump out... I pulled the shock bolt but the swinger doesnt come down far enough.... It's like it bottoms out on something else... ?????  | ||
| Rays |
Greg - I'm sure a real E2061 will fit correctly. When I bought the box with E2061 marked on it there was a completely different pump inside - different electrical connection, smaller strainer fitting point and to really rub salt into the wound it was used. | ||
| Greg_e |
I'm afraid I haven't tried to pull my pump yet so the only thing I can suggest is pull the belt and see if that helps, after that pull the swing arm pivot bolt so you can move it out of the way. You might try turning the pump 09 degrees clockwise, this will get the pump to a smaller profile and might let you pull it past the swingarm. If you can get to the E clip on the top of that shaft you could pull the filter and pump straight up into the frame and then pull the mounting plate around the corner, then pull the pump and filter out. Putting everything back in will not be possible this way. | ||

I got mine out by pushing the rear wheel in a as low position as i could. Mine is a 2009 Scg if it would make any difference. I had to turn it around a little and it was a tight fit, but it was possible! | ||
| Rays |
On the Uly I couldn't get the swingarm down far enough with the belt on. I popped the belt off and with the swingarm as far down as I could get it (I was dicing with personal injury doing this on stands - highly recommend you suspend the rear from something) the pump came out by twisting it as it came out as Greg suggested above. | ||
| Jfman |
Removed the belt and I removed the pivot bolt. Didnt have to remove the swingarm all the way. Then it came right out. The pump is cooked BTW. nothing happens if I hook it to a battery. I ordered on for a 2003 mustang V6. The guy at Canadian Tire said it's a Delphi pump. Hopefuly it works... What fuel filter do I need if I want to replace it? |
