Power to my belly tank fuel pump won't shut off.

[Rams]

Rode my fat lady two days ago, nothing unusual during the ride.   Returned home, parked her,  turned off the key and started to dismount.  Heard the fuel pump running.   That's not supposed to happen.   When the key is off, the power to the pump is off.

Turned the key on and off , the pumped shut off.   Thought, dang that's weird.   Started to get off again and all of a sudden, the pump started back up before I could get off.   Did this several times and the fuel pump kept coming back on a few seconds after the key was turned off.

After several on off iterations, it finally stayed off so, I went on with my other tasks of the day.   Upon returning the next morning, I found I had a dead battery.  Obviously, that fuel pump re-energized and ran the battery down.    

Could this be relay problem, an ignition lock cylinder issue or am I looking the wrong direction?    This has never been an issue before.   Any insight is greatly appreciated.   Buying a new battery today.

are you assuming we all know how you wired it?

No assumptions, it was wired in as the directions from R&M say to do.   Through the electric panel/accessory power point.   More directed to those that may have installed a belly tank.

Sorry I asked.   I'll just go find a Honda mechanic.

I think I'd try another cut off point with the key if it's not much of a hassle. By the sounds of it though the pump may have a short in it allowing it to run? I'd also run the wiring if you can to make sure there isn't an issue there. I'm just throwing things out there.

According to R&M instruction page, directions show connections made to the oem accessory wiring located behind the right side cover. Of course the are other ways to wire it I'm sure, but if this is your case, take a voltage reading there while disconnected. Then I suppose you need to start tracing wiring if it is hot with key off. Hot wire from pump will be white, the ground would be black. Good luck.

I wonder the pump's power wire (or maybe the auxiliary circuit wire) is somewhere shorted to a wire that has constant battery power.  Another possibility is that there is a problem within your ignition (key) switch preventing it from disconnecting consistently.  Begin troubleshooting with a test light at the auxiliary terminal.

If the pump is wired through a switched terminal block or a relay, that adds possible failure points.

for some reason your key is not shutting down power to the aux circuit. Maybe a faulty contact inside the key switch.

Appreciate all the pointers, will check them out.  Thinking it's a faulty relay but it never hurts to ask for advice.  Will let you know what I find.  Thanks.

check your 5amp acc fuse,if it's powered  up with the key off you probably need an ignition switch

Thought I would report back as to what I have done so far.   Couldn't do squat without the new battery.   So, bought one and installed it.    Checked fuses, all were good prior to installation of the battery.  Intend to get a new fuel pump relay.  Checked for bare and broken wires and connections, everything looked good so I proceeded with the battery installation.   Fully expected the fuel pump to kick on when the hot wire was attached.   Didn't happen..  

Finished installing and decided to turn the key on.   The fuel pump came to life just like it was supposed to.  So, thought I would give the starter a quick flick.   Seriously considered pulling the spark plugs first but didn't.   A more cautious (smarter) man would have.

Regardless, after a couple of quick flicks of the starter and everything seemed like it was supposed to be, I went ahead and tried to start the big girl.    She cranked and started like she always have.  I just got through with a short fifty mile ride, she performed flawlessly.   The only thing different was a new battery.    I'm not done with this, going to replace that fuel pump relay but, it doesn't make much sense to me that the battery was the issue.

Thanks again for the advice.

I can't see how a bad battery would cause your problems.

I can.
a weak battery will arc togather contacts., such as in relays. normally when they arc togather they stay togather. I'm with Ron on this one. replace that relay.
ever live in a house that relies on a well. those well pumps run off of a big contact relay.
if you've ever had what they call a brown out where you don't lose complete electric but the lights dim
if you tried drawing water when that happened it would weld those contacts togather because of low voltage.
same thing with 12 volt relays.
even in cars that had the old point system in the distributer. the points would weld togather if you tried starting it with a weak battery..
not saying that's what happened to him but it is a possibility.

The previous battery was a lithium (2.5 years old).   Probably at it's life expectancy.   Not sure, I don't remember it's warranty.    Tried putting it on a lithium charger but to no avail.     It went to the battery core pallet.  Too many things to do prior to departing for Roanoke but, I'll look for a relay when I get there.
