EDITED to reflect more current issue:

1986 GL1200 SEi (Fuel Injected)
16,000 miles
Just bought it last week

Hello Fellow Wingers:

I NEED HELP. I just bought this 1986 GL1200 Aspencade SEi last week. This Special Edition, Fuel Injected GoldWing has the digital dashboard and the faux tank mounted fuel/trip computer. The previous owner provided me with receipts that show that new timing belts and new tires were installed within 30 days, saving me the work of changing the timing belts, which was a huge buying point for me.

I was driving the bike at 60 mph yesterday, nearing the end of my very first day riding it, when suddenly the engine just DIED as if I had simply flipped the engine kill switch from RUN to OFF. I was unable to get it restarted…here’s what I have gone through so far:

At first, I suspected that I might have run out of gas, but that was not likely as I still had 1/4 tank. I added some fuel just in case...However, no matter what I tried, the starter would crank and crank but the engine would NOT FIRE. Even tried coasting downhill and popping the clutch, but still it would not fire.

I was concerned about the timing belts, because I had one break on a different bike years ago and the engine died in a similar way. So, after I trailered my GoldWing home, I tore into it and pulled off the timing covers to discover (to my great relief) that the timing belts are just fine, as are the tensioner pulleys, and everything under the timing covers looks as it should. At least I didn't mess up my valves and pistons, right?

Next on my suspect list to eliminate was my FUEL PUMP. I ran some jumper wires to the fuel pump from the battery, and the fuel pump RAN when I applied the 12v power. I tried cranking the bike with the power manually applied to the pump, but still the engine would not fire. Although the pump runs with power manually applied, I don’t hear or feel any fuel pump activity when cranking the starter. My understanding is that the fuel pump SHOULD run both when cranking the engine over and also when the engine is running. I've traced the pump wiring to where it connects under the saddle, but I don't see any problems, frayed wires or anything.

I have checked all the "dog-bone" fuses, and they are all fine.

I tried to check for spark, but was unable to determine if I’m getting any spark. I don’t think I am. When I sprayed some engine starting fluid into the air intake, the engine would not even attempt to fire, so at this juncture I’m thinking that NO SPARK is my problem.

In pouring over other technical posts about this and similar issues, someone suggested the KILL SWITCH could have failed, so I took it apart. The kill switch has two wires that go to it, the switch either interrupts or completes the connection between those wires. I tried starting the bike with those two kill switch wires connected, and tried again with them disconnected, but I think I’m still not getting spark. I have a non-fuel injected 1984 GL1200-I parts bike and I’ll replace the kill switch from that bike.

I’m planning to put my timing covers back on, as well as the radiator, etc. and put all that front end stuff back together because I don’t think I’ll need access to that stuff again since that doesn’t seem to be where the problem lies.

So here’s my question: Where do I go from here? What would cause the engine to shut down like this and not deliver any spark out of the blue while riding? I’ve checked the fuse panel under the faux tank, all the blade fuses are OK, but I don’t know about the relays. There are 6 "gold colored" relays and two "black/blue" relays on the same fuse block.

I went from riding to walking in 0.5 seconds flat. I’m very frustrated because I literally JUST bought this motorcycle and it was running great…until it wasn’t. I thought I had avoided any major repairs by buying a bike with new timing belts, only to be stranded.

I live in Frazier Park, CA, about 50 miles south of Bakersfield and about the same distance north of Santa Clarita & Valencia. Are there any GoldWing experts or mechanics who are within a reasonable distance? I have the motorcycle on a trailer right now, I left it on the trailer while taking it apart in case I needed to tow it to an expert. BUT, before I do that, perhaps there’s some input I could get from some of you experts and enthusiasts here on the site? I am going to post this on the two GoldWing sites I’m a member of.

Best regards,
Rob Eubank

Hi, I'll move this to the tech forum so you'll get more help.

Is it throwing a code? I'm not that familiar with the fuelies but it sounds like a pulse gen, or kill switch, or maybe even an ignition switch.

It won't show a code if there is no power to the ignition. I would suspect the kill switch, you should be able to take the top half of the housing off and connect the 2 wires together.

I would check the bank angel sensor as if is going bad it will shut the bike down. Just my 2 cents----------Hal

Thank you. I finally figured out how to post in the tech forum and so I did so...and I went into more detail about what happened and what I've done so far.

I don't know anything about bank angle sensors, but from what I've learned in scouring the forums, my pulse generator is on the back of my engine (fuel-injected version) instead of somewhere under the timing covers.

I took my kill switch apart, tomorrow I will connect the two wires and see if it'll work. It didn't work on my first try today, but by then my battery was getting low so I put it on slow charger overnight. If kill switch bypass doesn't work, how do I go about testing the other sensors?

I don't know how I'd determine if it's throwing a code. When I turn on the ignition, everything powers up, but engine cranks and won't fire. I don't think I am getting spark at this point. Hopefully you can see the post I put in the tech forum, maybe the detail I went into will help narrow things down a bit?

You have three pulse generators, one under the timing belt cover and two on the rear of your right camshaft.

I had already moved this thread to the tech forum, and now I've merged that new thread you started with this one.

I also moved the "Need a Mechanic" thread to the Motorcycle Discussion forum. You'll get more responses to it there.

I'm assuming that if just ONE of the three PG's fail, it could cause a complete shutdown?

I do have a carbeurated GL1200 parts bike. Is the pulse generator something I could pull out of my parts bike, or would it be SEi specific? I see several auctions on eBay listed for pulse generators, some of the new ones list multiple bikes, including the A, I and SEi for compatibility...

For the front pulse generator some have used one from a 1500 but half of an 85 or newer 1200 pulse generator should work.

For the one on the camshaft I know of no replacement other than from the 85 LTD or 86 SEi.

If I manage to pull the pulse generators off the donor bike, should these all be fairly plug & play? I mean, should they easily bolt in and plug in? If one of the PG's was the issue, should it start up? When I get home from work tomorrow, I will make an attempt at this solution. In the meantime, if there are any additional suggestions for things to check, I'm open. I will post all results of my troubleshooting efforts tomorrow evening.

Does the fuel system indicator light on the dash come on?

Problem solved - hallelujah!!!!

Dear fellow RIDERS!!!! I say RIDERS, because I'm going to be RIDING again just as soon as I reassemble my Wing!

The whole problem was a blown fuel pump relay, which also powers the air suspension system, and a BAD KILL SWITCH. I charged the battery last night and this morning joined the two kill switch wires and swapped the fuel pump relay for one from my parts bike. The fuel pump came on as soon as I touched the kill switch wires and it started right up!

When I get home from work today, I'll be reassembling my GoldWing and riding her to work tomorrow!

THANK YOU, THANK YOU, THANK YOU for helping me by process of elimination! I'm glad it was not the PG's!

I look forward to more time in the forums on other issues. I've decided to build one good GL1200 (carbeurated) from my two parts bikes, now that my SEi is fixed.

Best regards,
Rob Eubank
