1500 won't start after juming battery

Post by glk17l » Fri Oct 05, 2018 4:52 pm



My 1500 had a weak battery and wouldn't crank the engine strong enough to start. I tried trickle charging for a few days, and nothing. Then I used a car charger/booster. Hooked it up and had it set to 40amp cranking (the lowest on the 12 volt setting). When I hit the start button sparks came from the battery. I should have checked the battery first and I would have found that the trickle charger had dried out the battery (lead acid) over the winter. I installed a new battery. The engine turns over, but will not start. It seems not be getting fuel. All lights, gauges and radio, etc. are working. The main fuse is good, all fuses in the fuse box are good. Wondering if the is a hidden fuse some where that might cause it not to pump fuel.

Pull one plug wire and see if it has spark.

Yes there is spark. It seems that there is no gas pumping through the filter.

Check kill switch.

Check fuel pump signal from ecu wire to fuel pump when cranking.

And or check fuel pump by jumping power from battery to pump.

Thanks, I will check it in the morning. Is that the BLK/BLU wire on the ECU to the blue wire on the fuel pump? (with the ign on and the kill switch on). Hopefully it is just the fuel pump relay.

There is no fuel pump relay on your '93. Fuel pump power comes directly from the ECU electronics.
First would be to power the pump only with direct battery power, pump disconnected from ECU.
Does the pump run ?
If so, check the actual fuel output from the pump with the fuel line disconnected.
Within specs ?
Next, do you have power from the ECU to the pump when cranking the engine. It will be briefly powered each time you crank it, unless the engine starts running, which you cannot expect. Push the start button, crank the engine, you should see voltage to the pump for a few seconds.

BTW, I don't think I've ever seen it mentioned, but be very careful about the little sparks you will generate when you jump power the pump with a battery. You've got gas fumes floating around the area. Sparks ??? No good.

I jumped the fuel pump with 12vdc and the pump runs. I do have 12vdc coming from the ECU with the ignition and kill switch on when I hit the start button. I have to take the shelter off to disconnect the fuel filter to see if I have flow. There is a small black box that looks like a relay, (but the 4 wires going into it are hard wired, not terminals) attached to the top of the fuel pump. I checked several wiring diagrams, and manuals and none of them show what it is.

The mystery box may be a "noise filter" added on when a cb was installed.
The next question..Your pump runs with direct power...you mention the ecu has power feeding to the pump when you crank it...Is that with it hooked back up or just hanging loose?
Also the vacuum fuel valve may not open if you open the throttle when cranking the bike.

Thank you for your help.
There is power from the ECU. I measured it from the disconnected + wire at the top of the pump, to ground. Hooked everything up, disconnected the output line on the fuel filter, cranked it and there is flow. After all this cranking, I pulled a spark plug from each bank and they were bone dry. The vacuum fuel petcock was just rebuilt when I did the carbs and it worked fine last season (2017). Thinking electrical, maybe air jet solenoid valve or something obscure, from the dried battery ark.

Please do not make an assumption that the fuel is getting into the carbs.
Prove it.
Lift the top off the air cleaner and twist the throttle..does it squirt fuel from the accelerator jets?
Bypass the fuel valve if necessary.
Spark,compression and fuel is all that's needed to make it pop.
As needed..keep the battery charged too.
The air jets are for finite fuel control when running.Even if they quit,the bike should still start up.

That is my next step; to trace the fuel supply lines, starting from the carbs, up to the vacuum petcock to see where it stops flowing. Hopefully I can get to that tonight or tomorrow.

Once I check the rest of the fuel system, I will go back to possibly electrical, even tough all obvious system are powering up. I will let you know. Thanks again.

Since you've checked everything up through the fuel filter, my next check would be the petcock. A handheld vacuum pump would be handy for the specified check. If the petcock passes, verify there is adequate vacuum from the bike system to actuate the valve as well.
I would also check the measured fuel output to determine that the pump is not only pumping, but with adequate quantity or pressure.
At that point, the only thing left is the carbs.

Thanks Virg and Blue. I checked the carbs while cranking... bone dry. I disconnected the output on the petcock and cranked it...no gas flow. I disassembled the petcock, that I just rebuilt, when I did the carbs, about a year and a half ago, and the new diaphragm was shot. I will order another rebuild kit for it. Any suggestions for a good brand that will last. I checked with the local Honda dealer and they can only order an after market one, which is the same as I already replaced. It did look kind of flimsy compared to original Honda one when I was replacing it.

I just found the package from the petcock kit that I used. It was a K+L. Never again.

Cyclemax generally sells some pretty good parts.

I agree with Bluewaterhooker that Cyclemax is a good place to get parts for your Goldwing. I bought one of the petcock kits from them several years ago and it has been working fine ever since. In fact, I have bought a lot of stuff from Cyclmax over the years and I have been pleased with all of it.... and they are great folks to do business with.

Here's another option that other bike riders use.A electric valve.

I have purchased from Cycle Max before, and no problems.
That electric one sounds great, no gas seepage and fumes. Where can I get one?

I want to thank everyone for the information. I did wind up rebuilding the vacuum petcock, and after installing it, I hit the start button and it started right up. I am going to purchase an electric one, just in case. I went to take it for a test drive, and found that I had no rear breaks, no pedal at all. Pulled all the plastic off to bleed the rear brakes and check the pads. The rear and front left pads were good, flushed out the fluid in the rear and left front, and it works fine. I did the front right while I was at it. I never had to bleed the GL1100, CM 450, or the CL360, unless I replaced the break pads, or shoes. Again thanks to all for the input.

After all of that, I took the bike out for a short spin, 4 or 6 miles, and it ran great. Made a quick stop, and headed back home to put on warmer gear. It started to sputter, as if out of fuel, but the gauge is just above 1/4. I found that it was only under about 1500 RPM when this happens, and at idle it surges. I already resolved one idle surge problem when I rebuilt the carbs and replace the collapsed vacuum hose, under the carbs, that goes to the manifold. I checked the gas cap and the vent hose and it is good and functioning. I put some Sea Foam in it and ran it, let it sit for a day, then started it and it ran fine when it warmed up and shut the choke. Once it reached normal operating temp, the surge came back at idle. Any suggestions?

Seafoam is not an instant fix. It can take a few tanks of fuel to flush out any deposits. And if your problem is idle related, that means running the engine with extended idling. I'd use a good, strong dose, like a full can per tank, let it idle a lot, run it a lot, in several tanks. Then see if things don't improve. I know it solved my idle surging issue years ago. The "fuel sputtering" issue, I don't know. But, it's a cheap, easy try, and might be successful.
