I let my Ulysses sit for about a year, in that time a squirrel/rat got into the harness. I repaired what I could, but after the repairs the fuel pump wouldn't prime. Now, 6 years later I decided to get into it again. After making a diagnostic test wire I received codes 14,16,23,32,33, and 44.
I overlooked the engine temp sensor, and have one on order.
I have replaced the battery.
Could the injector codes be associated with the pump issue?
When I pulled the connector from the harness to the fuel pump, the ground was solid, i received +12 volts from grey, nothing from brown/yellow and nothing from yellow/red. Should I have different readings from the bn/y or y/r?
How can I test the pump to see if it is the problem, I do not have a breakout box.
Any information is greatly appreciated. |

Daniel, the fuel pump can be tested by providing 12 volts directly.
The grey wire provides +12v from the ignition circuit and the ECM provides a ground via the Brown/Yellow wire to switch the pump on.
This old post of mine that relates to testing the low fuel sensor shows the circuit connections and a way to safely connect to the pins with small alligator clips.

There isn't much real estate in that plug so I would connect that end first and then the positive (grey wire) and negative once you had that safely set-up.
After that much time I would think that fuel pump is possibly not well - my '06 sat for only 2 years with E10 fuel and the fuel pump assembly looked like it had been fitted to the Titanic. It was completely and utterly ruined - the fuel was black and had even eroded the copper from the wires. Fingers crossed you don't have that much damage. |

I really appreciate it Rays. I fiddled around with a few different configurations and couldn't get the pump to run. I do believe it is toast. It will get pulled later this week. |

Find and download electrical manual to troubleshoot the error codes the most effective way. |

Daniel, the pump on a Uly can definitely be removed without removing the swingarm. There are several old posts here that give good direction. I have done the job several times and I have suspended the rear of the bike via tie-down straps to the roof trusses in my shed. A couple more on the handlebar ends for stability makes it a pretty safe operation. I have seen others suspend the rear from a step-ladder. |

Tpehak, I have the service and electrical manual. Both require use of a breakout box for more advanced diagnosis. When I reach points where it requires the breakout box I will do the best determination I can with my limited capabilities and knowledge. From what I can tell the ECM is still functioning properly, I'm just trying to determine why I am getting the fuel injector and bank angle sensor codes.
Rays, I did something similar about 10 years ago when I needed to replace my back tire. this time it will be different tie down straps and different trusses.
thanks |

In most cases the breakout box just checks some wires or circuits continuity, you can replace this procedure by electrical tester. If you read carefully you can figure out which wire to check, you can find necessary pins on the plugs and wires on wiring diagram and check continuity of the wires or circuits between the pins.
