Fuel tank drain/ Fuel pump fuse

Post by MarkBirm »



Okay master mechanics, I have been thrown for a loop. The problem is this, 2002 GL1800, 575 TOTAL miles. has sat for six months without being started. Battery on a tender. Now the bike will only turn over but not run. I know that the gas needs to be drained after sitting so long, is there a drain plug? or do I need to syphon off the tank? Is there possibly a fuse or relay for the pump that I can check? I was told fresh gas was introduced into it about two months ago, that's the reason I'm asking about the fuse or relay. Thank you for your input.

You should hear pump run for a couple of seconds immediately after turn the key to the ON position.

Having the seat off should make it plenty loud enough to hear.

No drain on the tank (plastic), so the tank is removed, and the pump removed from the tank for it to be drained thoroughly.

EDIT: Sure you have spark?

2002 GL1800 with 575 total miles and you say it has sat for 6 months? It really seems like it has sat somewhere for a lot more than 6 months.
Where did it sit? Were there rodents anywhere near the storage location? They can usually cripple the best piece of equipment in short order.

My 2003 GL1800 sat from August through March (6 months) in 2014/2015 without ever being started. It was down for major maintenance after an accident. It started right up after 6 months of sitting. I don't think old fuel is your problem.

Okay, I will check to see if I can hear the pump. Finally found all of the fuses to be okay. Not sure about the relays, even though I switched a couple around.
Going to replace the plugs and see what happens and to verify that there is spark.
Thank you for the ideas.

It has sat inside of garages and had a cover on it, I have not seen anything to suggest that the rodents have gotten to it.

Inside a garage, especially with a cover on it, is a lure for mice. Mice love covered things.

Well the bike still not starting. the fuel pump clicks a couple of times, that's it. I changed the plugs, same results. I am thinking the pump is the culprit, but with only 575 miles, it just doesn't seem right. Disconnected the battery for a couple of minutes to see if maybe there is a code in the computer, didn't help. Thought about spraying some ether into the air horn to see if that might wake it up and possibly verify that the pump is kaput.

Thoughts??

575 miles is most likely the culprit. It would be a lot better if there were a few more digits to that number.
So basically the fuel pump has been soaking in old fuel without moving for most of it's 20 year life. I would not be surprised if it is locked up from that. You can check it with a pressure gauge and a volt meter to verify. Make sure pump gets voltage, then check pressure.
I think you can expect quite a list of things that will need to be addressed. Sitting takes more of a toll on Goldwings than riding.

Agree. Certainly would suspect that the old fuel has sat there and all of the volatile components have evaporated. Addition of any new fuel has a good chance of gumming up the passageways to the throttle body with the old crusty crap.

This web page has a couple of photos for the OP to have a good look at the complexity of the GL1800 fuel pump:

I'd certainly be at the point in this job to pull the pump and have good visual inspection. I think while I was that close, a good clean-out of that fuel tank and fuel line from pump to throttle body would be next.
