Hey Everyone, I just picked up a 2012 Dyna Superglide in non-running condition, but immaculate otherwise. It only has 3,100 miles and sat for 5-6 years prior to me buying it, and was ridden very infrequently before that. I hooked up a brand new battery and she came to life perfectly, all lights work, odometer works, etc. She turns over perfectly, but no priming / fuel pump shows no life (I put fresh gas in). The code being thrown is b2116 aka "fuel pump circuit open" and the part number the bike is giving me is 69992-12 which is the BCM. I've done plenty of research and all roads lead to either a crimped wire somewhere, or the BCM has just gone bad, apparently that's common. The previous owner (only owner prior to me) is in his 70's and never changed anything about the bike, it's bone stock, he never even took the seat off. I highly doubt a wire has been tampered with, and he said it was running just fine before he let it sit for years. This brings me to my real question, can I just pop in a used bcm from another dyna with the same part number? This is a *NON* security bike, no fobs. Will I need Harley to code this new bcm to the bike? They told me they won't, but I thought I'd write here too. I can't find any info on that piece of the puzzle.
Related question, the original part number is now superseded by 41000351-G, but that part is $475 new from Harley. I can pick up a used BCM on eBay for $100, but am I wasting money on that since it's also old and has the out-dated part number? I feel like it should be fine, but what do you think?
Thanks very much for any help!!
ps - only thing I haven't tried is a redneck test with some starter fluid. I'm pretty sure that's going to work just fine, but I'm going to try that to rule it out today. Thanks again.

I'm not sure what that means, but if I had to guess I'd say the BCM is the one reporting the problem, not the source of the problem. "fuel pump circuit open" is pretty straight forward: it means the fuel pump isn't drawing any current. This could be a broken wire, a bad connector, or it could be a bad fuel pump. I'd look there first. Is there voltage at the fuel pump? Is it grounded? Look for a simple problem first.
I had a 2014 Super glide and replaced mine after a shorted wire blew it out. Got a used one and it had to go to Harley to get programmed or mated to the bike. I don't know if a 2012 has a Can Bus system but mine did even though it has throttle cables.
Congratulations on your first post to HDF,
to the Forum.
Before you go throwing parts at it, go through a diagnosis logically:
Have you checked the fuses to ensure they are all seated correctly and not blown? Check the fuel pump and accy. fuses.
Have you checked the fuel pump circuit with a meter to see if there is power going to the fuel pump and it is just not functioning ?
Could be a bad internal connection on the fuel pump within the fuel tank.
Could be the fuel pump is frozen from old gas (probably not)
If you go into the fuel tank you might as well replace the fuel filter while you are in there.
thanks so much!!
Re: fuses, I can find lots of info on the earlier fuse boxes which have the 2 relays in them + around 10 fuses, but mine only has a main fuse and 2 other smaller fuses, at least thats all thats under the left side cover. Am I missing the specific fuel pump and accessory fuses?
ill check the pump with a meter first! Good call.
old gas is not off the table, had to buy a new check valve it was stuck from old gas.

thanks for that! Gonna try and sort it out without buying the bcm first, but great to know.
2012 is canbus, so if you buy a used BCM make sure it's the right one. The non canbus BCM's won't work. I had a similar problem on my 2007 dyna and it was the starter relay. I'm pretty sure (but not positive) that the canbus wired bikes no longer have a system relay, but it might be worth checking.

Yes I believe that's correct, I was searching all over for a system relay since pretty much all of the solutions I can find online point to that, but these don't have one.
UPDATE: Thanks to ya'll I didn't buy a BCM and checked into the wiring where I'm losing power to the fuel pump, the BCM isn't faulty. The problem is the fuel pump itself. Power is getting there, but she aint kickin on. I'm guessing it just sat in old gas for too long even though it looks mostly pristine and bright white, but who knows what's going on inside. Also, once I pulled it out, one of the hoses was completely broken in half. It's brittle and broke even more when I barely touched it. New fuel pump and hoses ordered, as well as fuel filter, and regulator, all from Quantum. Also picked up a new check valve. If anyone in the future is looking into this same issue, Test for power on pin F4 on the BCM, then at the Red/Brown wire in the connector under the speedo console. Note that you'll only have power for about 3 seconds when you flip the run switch on (the normal amount of time the fuel pump is usually on during priming).
I'll report back once the new fuel pump is in. Thanks again.
