1985 LTD wont start

Postby washandy98664 » Fri Jan 23, 2015 9:39 am



I have an 85 LTD that wont start.
I last ran it about 3 weeks ago and it was fine.
I go out to start it and no Tail light and no fuel pump engaging for a few seconds.
Check all the fuses in the faux tank in the fuse block, but all are fine.
Been reading that some people are reporting a fuse in the left side of the fairing.
Can't find that one.
So what would cause my tail light and fuel pump to stop working?????
Any and all responses are appreciated.
Thanks Andy

I forget... the LTD designation means fuel injection, right?

There is a supplemental manual for the "EFI" bikes. I have a copy at home and if you don't have one (I think I downloaded it for free in .PDF format) I will email you a copy if you want it.

Running from memory here... the fuel system on the "Fuel Injected" Goldwing operates a great deal like the early "fuel injected" auto engine, without the O2 sensors included nor catalytic converters.

The ICU/ECU (can't recall exactly what Honda calls the electronic control module) receives input from several sources. There's a cam-shaft angle sensor, a crankshaft angle sensor, two plenum sensors (they pick up plenum/intake runner pressure) and possibly a sensor (probably a Throttle Position Sensor) or two I can't remember. The electronics sort out all this data and provide a signal to what I call throttle bodies (I'm sure Honda calls them fuel injectors) so that the "correct" amount of fuel is dispensed into the intake tube(s) just upstream of the elbows. There is one injector for each "side" of the engine...

Having said all that, I'd begin at the bginning and work my way toward the end, meaning I'd start with battery terminals and work my way toward relay(s) and other connectors, including any and all grounds to ensure the electricity from the battery can actually get to where it is supposed to get before I started into the circuitry that determines when it goes where it wants to go.

If you take the battery out to start, you can put it on a charge while you're cleaning and re-attaching so that when the time comes to try it out, the battery will have a full charge... and if you want that supplemental manual, PM me with your email address and I'll send it along... won't even cost you a stamp.

I am wrong as often as I am right concerning what is wrong with someone else' motorcycle without having seen the machine in person. Guessing with limited information, as to the source of the trouble, is sketchy at best.

I took the battery out this morning and cleaned all connections and the dog bone fuses.
I finally heard the fuel pump engaging and it started .
Came back later and no fuel pump sound and no start.
At this point I would have to say my fuel pump is bad.
Got the bike early last year, did all the basics to bring maintenance up to date and rode her for about 7500 miles.
I ride almost year round, they make cold weather gear for those frosty days!!
Anyway gonna order a fuel pump now.
Thanks for the reply.

Before I put a fuel pump in it, I'd look over that supplemental manual (I just emailed it to you) and I'd be sure the fuel pump is "getting the message" to turn on and run from the rest of the electronics... it could be something VERY simple.. or not.

Best of luck to you... and if you have questions about the schematic for the fuel/starting wiring, feel free to email me at the address I sent the manual from, and I'll trace out the wiring with you. It's been a while since I looked at it, so I'd have to start from the begining. The fact that it does work once in a while is encouraging to me.

Have you checked the second dog bone fuse that is located behind the starter relay just behind the battery?
I've replced both dog one fuses on my ltd with inline bled fuses.
There is a fuse in the left side of the fairing under the left storage box.
It's a 7.5 amp fuse

Alright, I got my new fuel pump in today.
Replaced it and no go......
When I go to start there is no sound from the fuel pump engaging.
Now it looks like the fuel pump was not the problem.
Any guess or information would be greatly appreciated.
Thanks Washandy98664

Do the lights cycle on the ECM(CFI) module... (if it has them)....I'm wondering if the ECM is getting power...
This post may help... viewtopic.php?f=5&t=25613
Is there the CFI relay.?

Sounds very much like my LTD when I first got it. Turned out to be a faulty relay in the fuse box.

Found the problem a while ago just forgot to update....
The wiring connector located on the rear fender, under the seat was loaded with fine dirt causing no connection.
Cleaned it real well, runs great again.
