I installed this last fall, had the carbs rebuilt over the winter and it’s been working fine. Yesterday coming home started crapping out coming home and next morning realized the fuel pump isn’t getting power but can’t find a fuse or relay for it even after doing some research. Verified no power by grounding test light on battery and cut the power wire and have no power there?

Fuse or bad pump relay?

How is the pump connected electrically, which way did you use?
Also what year and type is your bike, it would be good to put that in your profile for the future.

I don’t know can’t find the fuse location for it haven’t had time to do much tinkering on it do you know where FP relay and fuse are?
it’s just using the factory hot wire and ground bike is a 98 ST1100
So looking at the diagrams FP cut off relay? Anyone know where this is physically located on the bike
Have a look at this thread

Fuel pump not running | ST1100 Related
Fuel pump isn't running on my 91. (via ignition, which is fine). Pump runs fine when jumped directly to the battery. What and where to look ??

It's inside the upper left of the fairing. number 8
I finally figured that out but thanks been a busy day!

Thanks John! I appreciate that!
And From what I understand this relay is propriety Honda one which makes me wonder what made it pop if that’s it haven’t had time to look at it. My joints to the fuel pump were fine nothing shorted out or anything. We’ll see soon my off day tomorrow.

I'd run a hot fused wire directly from the battery to the pump just to eliminate the pump as the culprit.

I'd pull the connector to it inspect and re-plug it, that can clean contacts to some degree.
OK I removed the plastic and believe I found the correct relay I will attach a few pics. I did jump the fuel pump directly to the battery so guess that would indicate my almost new FP just took a dump? But I also checked tor power to the brown wire which is the factory hot to the og pump which is still in the tank. It is grounded where factory ground was. I’m just kind of confused here?
