First off I need to thank you for all of the written guidance I was able to find on this forum. It is truly amazing the community of Wing experts all assembled in one place.
Here's my story:
I had my 1990 GL 1500 garaged for the winter as alway on a battery maintainer, unfortunately, the battery died this winter. I gave it one last attempt at a charge and got the bike started, rode around the block to check things out and parked it in the Garage. That is the last time it started on it's own.
Purchased a brand new battery.
The bike turns over
Noticed Fuel was not flowing through the filter
Replaced the fuel filter (as by this point I had most of the bike apart)
Checked All fuses with a voltmeter
Tried to test all the sensors that would prevent me from starting
Validated with Honda the Bank angle recall was done on this bike
Jumped positive to the Black/BLue Fuel pump wire and the Pump is working filling my fuel filter
After this, I can start the bike, but I only run what is in the line, I do not keep power to the Fuel filter
I figured next would be the ECM. I ripped into that and jumped the BLKlWHT and BLK/BLU
Tried to start the bike and I had fuel filling the filter and again I could run the bike in this mode.
After reconnecting the yellow ECM plug back into the ECM, the same thing occurred where no power is going to the fuel pump.
Long story and my ask is could it still be the banking sensor? I have read that there is no relay involved but on the schematic, it looks like a relay may be involved, is there a way to test a relay?
Any suggestions on where to go next?
Disappointed as we all should be riding this time of year, and I am sitting with a pile of parts scattered in the garage. Any guidance is appreciated. I am proud of myself for being able to follow all of your great instructions thus far, once i resolve this, i hope i remember how to put it all back together
