Multiple Questions about this 1990 GL1500

Post by JohnnyB53 »



First of all, this website is fantastic. I have learned so much in such a short amount of time from all of the knowledge and experience through these forums and DIYs. Now here is my situation. Sadly my dad passed away and while helping my mom get all the financials and house projects taken care of, I made it my goal to also get his Goldwing GL1500 up and running and for sale. Overall it looks in good condition. I am having trouble getting her to actually start. But the craziest part is, it is 2023 and this 1990 bike has approximately 8000 original miles on it. I did not miss a zero. This thing has only eight thousand miles on it. So when it comes to valuing it, I haven't found anything to compare it to. I have it mostly pulled apart right now in a messy garage so I will add pictures after I put the plastics back on and get the dust off but. I would like to see if I cant find a Goldwing enthusiast for it to go to. I realize she an older bike but the more I have spent time with it, the cooler it gets so I need it to go to a fitting home. I would keep it, but the bike is here in the south west, I now live in the north east and just do not have the space to store it for the non-riding months nor the funds to move it and keep it insured.

Back to the not starting issue. Here is what I have done so far:
-Drained, replaced fuel.
-Changed Oil and Oil Filter.
-Replaced Air Filter.
-Replaced Battery. (I have Lithium Ion for my bike back home and it works great so I replaced it with one here. Unfortunately I found this site after that and read all the forums saying I probably shouldn't have done that but I have verified all attempts to start have been with appropriate voltage)
-I will be replacing the fuel filter and spark plugs today so I will follow up on if that changed a thing
-Verified all fuses are intact

Here are the symptoms.
-With the engine shutoff switch in "RUN", bike in neutral, on center stand, the starter cranks and cranks and cranks but ignition is never achieved.

Back to the basics. So you need air, fuel, spark.

When you've cranked it for a bit, smell the exhaust. Do you smell any fuel there? If not, find out why you aren't getting fuel.

Pull a plug and check to see if there is spark when cranking. If not, start investigating that as well.

I replaced the fuel filter and tried to start the bike. I cranked it for a good few seconds a few times and never got a whiff of gas from the exhaust ergo, fuel does not appear to be flowing. I pulled the gas tank lid under the seat and noted the thicker black hose to the metal pipe running down the center of the inside of the tank is fairly cracked around where it would be making a seal. Not sure the purpose of that portion of line but could this be a fuel flow issue?

Unlike many bikes that use a fuel pump to suck fuel out of the tank (in which case a cracked hose means it will suck air instead of fuel), the GL1500 has its fuel pump inside the tank, and it pushes fuel up and out. So if the hose is cracked enough to leak, you will have fuel leaking out of it when the fuel pump is running.

I would try disconnecting one of the hoses on the fuel filter and put the end of it into a container, then try to start the bike and see if any fuel is actually flowing out.

Replaced the hose, submerged pump and reconnected to bikes power. Directed the discharge of the pump upstream of the fuel filter to a bucket. No flow when cranked. Verified voltage is seen at the pump terminals while cranking. Thinking its definitely the pump at this point. I read previous forums about replacing it with the NAPA 72190 fuel pump but it doesnt seem that NAPA carries that any more. Has a different non-OEM pump been identified?

Aftermarket pumps that work are tough to find. They need the correct flow rate and pressure. Too much pressure, it will push past the needle valve in the carbs and flood the carbs. Insufficient flow, and you'll bog down at highway speeds.

A long shot, but you might see if you can resurrect the OEM pump this way:

Can't hurt to try if the pump is already considered to be junk. Probably won't work if the pump motor is simply worn out, but if it is gunked and seized from sitting in bad fuel for a long time this might be enough impetus to make it spin again.

With the pump removed from the bike, see if you can come up with two 12v batteries, the battery from your bike plus jumper cables from your car will work if you don't have other batteries about.

Hook them in series. You can do the bike and car batteries easily, connect the Positive clamp of the jumper cable from your car to a convenient ground on the bike, clamp the Neg cable of the jumper cable from the car to the chassis of the dead bike fuel pump. Run a wire from the Pos terminal of the bike battery and touch that intermittently to the power terminal of the fuel pump.

You'll be feeding 24 volts, not 12, to the pump. and intermittently jolting it with 24 volts might just break the stuck pump motor loose so it can spin again.

You'll be able to hear if the motor starts running, if it starts going don't run it more than a couple seconds with 24 volts. It is designed to run wet with only 12 volts, put the business end of the pump into a tupperware tub of Seafoam and see if it can pump that with the normal 12 volts. Put a hose on the pump output to feed the seafoam back to the tub so you don't waste it, and pump the seafoam with 12v power a little while. This would clean and lube it.

Kinda thinking outside the box here, but with the difficulties sourcing a replacement pump I can't help but think it would be worth a try. :ugeek:

How long has it been since this Gold Wing was ridden on the road? If you look in gas tank do you see rust and corrosion on inside surface of gas tank? You could also be looking at needing the carburators overhauled. Possibly brakes and clutch master, and slave cylinders need attentiion. Of coarse, new cam belts if you do not know when they were last changed. Change anti freeze, tires could be dey rotted. It could take lots of time and money to get this Gold Wing on the road again.

The good thing, the pump is still available from Honda. Just not cheap.

16700-MAF-000 is the part number. Check with your local Honda dealer or buy on line.

When you pulled the pump out and drained the tank, did you inspect the tank for rust and debris? What did you find?
If rust is present in the tank you will need to clean the tank, electrolysis works great or you can buy 7 gallons of Evaporust (expensive)to completely fill the tank. Other ways are apple cider.
