2000 GL 1500 won't start

Postby papa02 » Mon May 07, 2012 8:36 pm



This is my first post on goldwingdocs, I have a 2000 GL1500 SE which I purchased about 7 months ago. When I purchased the wing it had 15000 miles, it now has 19500 miles on it and I have had no problems until last saturday. Had been riding all day with my CMA buddies and was returning home when it "sputtered" a couple of times and then died. The starter would engage and the motor turn over just would not start. Got it home and got to break it down, checked all fuses, all where good Checked to see if it was getting fuel, and found the fuel pump was not working. Checked and was getting no power to the pump, went to the ECM and jumped the blu/blk and blu/white wire as indicated in the service manual and the pump worked. My question is have I found the problem, bad ECM or do I need to check anything elese, any advice for novice mech.

I wonder if it's got spark?I seem to remember that if you hit the kill switch,it not only kills the spark,it will kill the power to the pump as well.

As I understand it.The pump is only energized when there is spark.
Pull one plug wire and put on a spare plug.Crank it and see if there is spark.If none,wiggle the kill switch a few times and try again.They do fail.
Could the bank angle sensor has failed and killed the power to the ECM ?Worth at least testing .

If there is spark,you could bypass the ECM output to the pump and get the pump running. .Disconnect the pump wire at the tank and connect it to the battery with a fused wire.
Try to start the bike.This will eliminate the ignition part of the ECM as a problem.

I remember a post a long time ago about a dead fuel pump.I'll see if I can dig it up.I'll also look into the schematic,and poke around a bit.

Regardless of spark, on the 2000, the fuel pump should operate for a few seconds after the ignition switch is turned to ON. If it does not, then check main fuse B and fuse 11.

I'm assuming those fuses are good.

To isolate the ECM as the cause, pull the connector off the back of the ECM (it's on the right side, right underneath the fuel filter). Short the Black/Blue and Black/White wires in the connector together with a small wire:



Then turn the ignition to ON. The fuel pump should run continuously. If it does, then the problem is with the ECM.

If the pump doesn't run, then disconnect the Black/Blue wire from the top of the fuel pump/sender on the top of the fuel tank, and apply 12 volts directly to the connector on the fuel pump/sender assembly that you just disconnected the wire from. If the pump runs, then the problem is a connection or within the harness between the ECM and the fuel pump. If the pump doesn't run, then the problem is the pump itself.

I don't have a 2000 just a lowly 88,
Yes,even on mine,when the key is first turned on the fuel pump will cycle for a second but to continue to run it needs a pulse from the ignition primary signal.
I do know that my pump will not run until the engine is cranking or running and the kill switch will not only kill the spark,it kills the pump by killing the ignition.
The 88 uses a separate module under the seat to run the pump and is sustained by the ignition primary pulses.I believe the later models just combined the 2 modules together,but use the same theory of operation.
Yes the ECM can fail,but I'd only replace it after all the inputs have been tested.Power,ignition pulse coil,etc.
I truly believe if there isn't spark there won't be any power to the pump.
Here's the schematic and things I think must work to get the pump to run.

Really? I seem to remember reading somewhere that the "fuel pump cycle for a second" when turned on started later in the GL1500 model series? I could be wrong however, that's been known to happen, especially when I go by memory. :)

Mine cycles for 1 second when the key is first turned on.I grabbed that power to operate my flasher circuit and found it was dead until I either cycled the key or the kill switch.

OK first off thanks for all the great post and advice I ordered a ECM from ebay and got it in this evening, went to my buddys house where the wing is and we installed the new ECM, turned key on and still no fuel being pumped, put the fuel line back onto the filter and I told my buddy lets take 12 volts straight to the fuel pump and get some gas in the carbs to see if we have spark and to see if the motor will start, did that and varoom, varoom it started up, and keep on running, rechecked voltage was great, checked fused again all good, stoped and started the wing several times no problems. We let the wing run for awhile and started putting it back togthere and after each part started and stoped the engine. Got it all back togthere took it for a small test run, everything checked out great all systems go. I really do not know what we did, or did not do, guess the good Lord was looking out for me, anyways will take several small trips see how it goes, any thoughts or sugesstion, and again thanks for all the post.

So did you leave the fuel pump hooked up to 12 volts, or did you hook it back up to the ECM when you put it back together?

A thought....12 volts direct to the pump.....When it started,the pump filled the carbs....Unhook the pump and the bike has enough gas in the carbs to start and run for a good while.

Before the seat was put on,did you verify the pump is now getting volts with the bike running ??? or now just running on what was forced pumped into the carbs from the direct hookup?
Second question.Is there a small(1X1X1/2") box on top of the fuel pump mount with 4 wires on it?
Mine has one,it's a noise filter,did you bypass the ECM and hook to the pump wire to it or the connector on the pump?

Did not leave 12 v hooked up went back to ECM and was getting 12 volts, mine does have that small box on top of the fuel pump. Everything still working like a champ this morning.

Boy you got me.
Somehow you sprinkled enough pixi dust on the connectors to shock it into running.
Makes me wonder if the old ECM is still working and something that was done elsewhere was the real problem.
Maybe a corroded connection?
How about this random theory.....
The ECM may also monitors current draw to the pump and if draws too much from binding,worn bearings,debris in the impeller,it shuts that circuit off to protect the ECM from blowing a fuse.
Now that the pump has been shocked into running direct from the battery,it settles back to normal and the reset ECM returns power.?

I can only speculate,but you might want to keep a FUSED wire and connector on the bike.Just in case it dies again on the road.At least you'll know how to bypass the ECM to get fuel.
Actually,It's good idea for the gander too,goose. :D I think I'll do the same thing,you know,just in case.

Has me wondering too, planing a raod trip to orzark mountains first of June, would really like to know what happened, will be making several small trips in the meantime to see if the problem happens again.

Hello everyone. First let me say how impressed I have been over the past several weeks at the amount of amazing information and how wonderful Goldwing owners are to fellow owners. I have been reading this forum for a while and I just recently experienced an electrical fire on my '93 GL1500A. I am currently rebuilding. Well after installing another wiring harness, my fuel pump wouldn't work. I could jump from my battery to the pump and it would run.

I followed the instructions on this thread and was able to have her running in no time. My wife and myself are so excited to have our best friend back. It's pretty close to losing a family member, not quite, but close. LOL. Anyway, thank you to everyone who has posted such priceless information for members to read and learn from. And all for free. Please keep up the great work. I am considering posting the pics from the fire as well as the rebuilding job. Take care.

After 35 years of electrical service it still amazes me how many times a simple unplug and reconnect can correct a problem.

Well I agree. You would think with the types of connectors used, it would be impossible for them not to make a proper connection. Just glad it worked.

Sorry to hear about the electrical fire.
Did you determine the cause of the problem.???
I'm most interested in preventive measures.

So what?................
I'd like to know if there might be a impending fail point on mine that could cause a fire...

Or it could have been that you didn't notice that was posted 3 years ago............ :P :P :P
As much electrical knowledge as you have, you already know if there's an impending fail point on yours. Not buying that excuse :lol:
