1985 Limited Fuel Problem, PLEASE Help!

[farleypug]

I would like to say thanks in advance to anyone who can help me with this question. I recently picked up a 1985 Goldwing Limited Edition from the original owner with 18,000 miles. Well, it hasn't been on the road since 1997 and I am trying to bring it back to running condition. First I had to put a new fuel pump in because the old one went out. Now it has great pressure going all the way to the fuel injectors but the bike won't fire up without starting fluid. I don't think the fuel injectors are firing because the plugs are bone dry. I took a test light to the power wire on the injectors and they have power, but I don't think that they are pulsing. When I turn the bike over, the test light is constantly light and I think that it should be pulsing. I did find a couple wires that had been chewed by a mouse going into the fuse panel. I fixed those but I still have no luck. Does anyone have any advice other than trying a new ECu? Fuel injection is beautiful when working, but it's a headache when it's not. Thanks everyone.

I just got my Clymer manual in the mail and read up on a few things. It says that if there is a fuel delivery problem, one of the LED lights on the ECU will blink a code. When I turn the key on, all five lights come on, but then go off after about 1-2 seconds. They don't blink or stay on. Also, all of the dash lights go off except oil because it's not running. Could the ECU be bad? Does anyone know if there is a way to check the ECU? I'm guessing that it's like a cdi box and there's really no way to check it. I'm worried because the manual says to not jump the bike because it would ruin the ECU and I know that it has been jumped. If I can't figure it out, I'm just going to sell the bike for parts or something. Thanks again everyone!!

Keep us posted if you decide to part it out

I'm now getting a reading on the ECU that indicates there is an open circuit/shorted signal wire on the left-hand camshaft angle sensor. The 3,1,0 lights are blinking and the "w" light stays lit. Would this cause the injectors to not fire? Can anyone break this down for a simple mind ? Hopefully this is a simple fix. Thanks and sorry for all of the ridiculous posts!

I would check the following: Is the cam sensor connector plugged in and does it have a good, tight fit, with no corrosion?; Does the cam sensor have the correct resistance?; Is there obvious damage to the sensor?

Most problems that I've seen on the Ltd injection system have been relatively simple. Mostly loose connectors and wires chewed by mice. You really need a copy of the Honda ETM (Electrical Troubleshooting Manual) that was put out specifically for this bike. I'd hate to attempt any electrical diagnosis on this bike without it. It takes a while to figure out how to use the manual, but it goes into great detail, showing exactly where every connector is located on the bike, etc..
Not sure, but I think if you go to the "Manuals" section on this website, there's a link to Helms, the company that prints the Honda manuals.

Good luck and let us know what you figure out.

Wonder if ne ever got it started ?

I would love to know that too. I picked up one from a farmer in Iowa, had 29K miles and stored inside. He quit riding it when it quit charging and he took it to dealer and found it would cost around $2K to have fixed. I got really lucky (for once) and soldered the wires and it charges like a champ!

I have one of these as well as a 1500 and these are awesome in performance. A pain to diagnose and adapt parts to but when they run correctly they are mini rocket ships

How did he get the ECU to start reading anything, after it would not to start with?
I have a 1200 LTD also. 100K without a niss and now troubleshooting a miss. I cannot get my ECU to read anything but red lights for a second when I turn on the key and then nothing.

Old thread, but relevant to us that own these '85 FI bike(s).

I'd check the fuse for the CFI system. It is the one beside the battery and the wire is connected to the battery terminal of the starter solenoid. If it is the old dog bone fuse, jump it and see what happens.

If this does not correct the issue, I'd check the power to the main fuse panel from the ignition switch.

When the key is turned on does the dash go through a start up sequence, cruise lights on then off, Fuel System light on then off, and such.

Does the fuel pump start then stop after 2-3 seconds!

Having mentioned the above, sounds like a power issue.

Good luck.

Thank you Rednex60, Yes the bike goes through the full proper sequence when I turn the key on. I have two of these bikes, and they both do the same thing properly when I turn the key on, including the fuel pumps running a couple of seconds etc. It's why I wonder if I'm simply missing a simple step that makes the unit display. I get red LED's for a second and a half when I turn the key on like its supposed to, then blank. Is it possible the troubleshooting computer reads blank if there is nothing wrong with the system?
I'll double check the fuses as you suggest. Thanks again.

I'm a little confused. Does the bike start? If all the signals are correct the ECU will not display any error codes - no lights will be illuminated. If the bike starts and there are no error codes, there will be no lights.

If the bike goes through a normal start up when you turn on the key as you mention, if the Fuel System light goes out there will be no error codes on the ECU.

Ooh man thanks! I get it now. Yes the bike starts and runs fine. And the fuel system light goes out. So the miss I'm getting is not anything the computer would show. (Hopefully just a little bad gas, though I haven't ruled out a failing throttle sensor.)
Thanks again,
Bruce
