Time To Pull The Pump (again)

[Big_Jim59]

When last I looked at it, I had just pulled the upper tank sending unit, found a broken wire and very carefully mended it. Then I tested it and found that I was getting the proper range of values through the range of the float arm. I reassembled it all, filled the tank and got full bars. The tank is down past half and I still get flashing fuel gauge with it showing full bars. To be honest I am a little disappointed. I figure I am going to need to buy a used fuel pump unit off ebay so that I can get the factory thermistor which I think is the cause of my flashing issue..

I am also still chasing a FI code #9. I took a break to replace the brake fluid but I am sure I will have to get into the throttle bodies to make any more head way there.

Got the ST1300 out today for a startup and run up to operating temp in the driveway. Bike is 10 years old now and just shy of 40k. It started right up but immediately had running issues. Ran rough,died a couple of times and FI Light came on and would not go off. Tried a couple of restarts...

I did read that article and that was my next stop on this journey. To get there I have to pull the air cleaner and get down to the throttle bodies and I just haven't had the heart to do it yet. I have had the bike scattered all over the garage for the better half of a week and I wanted to make sure it got back together before launching into another project.
