1985 Limited Fuel Problem, PLEASE Help!

Postby farleypug » Mon Nov 01, 2010 9:13 am



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!!

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 :roll: ? 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.

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
