There is a black box underneath the trunk. On the left hand side you should see a series of LEDs. This is where you should see the code patterns.

I am at work right now and can help later today when I get home and look them up for you if you want.

Have emailed manuals to him.

The ECU should light up when key is turned on, and then everything going out is the way it should be. If this is what is happening there is something else that is the issue besides the electronic ignition system.

Will read your thread again. No spark seems to be the issue. I would also look for a loose connection at the coils. Take the shelter off and make sure the wires to the coils are on tight and secure. The black/white wire going to the coils is from the engine shut off switch (kill switch), the other wires go the spark igniters.

Good luck.

I have the shroud off all connections look good and tight.I have pulled apart a few all clean no corrosion ... i have been told that the PG's could be the issue, as they will just lose spark at random times, Its like someone turns the Kill switch off, I have tore the kill switch apart and its perfect inside, even when the bike doesnt start I can hear the fuel pump kick on so I know the Kill switch is working properly... don't know if this makes a difference or not, but it does it hot or cold..so its not a warming up and quitting issue..its random ..H or Cold....

There are no PG sensors on the '85 LTD. You have an Ns sensor located in the timing belt compartment for engine timing. There are Gr/Gl sensors located on the back end of the right cylinder head for injector timing; however, the ECU uses all sensor inputs for engine timing/operation. The carb models have PG sensors.

The bike will not start if the Ns sensor is faulty, and/or if BOTH the Gr/Gl sensors are faulty. The other sensors can be faulty but the fuel injection and engine timing will be fixed.

You have to have had the engine started to have an Ns or Gr/Gl sensor error code. When you do get the engine started, and if it stops, do not turn off the ignition key. Check the ECU first for error codes because the error codes for faulty injectors, Ns and Gr/Gl sensors will go out and not be indicated again until the engine is started again.

Hope this helps.

Cheers

When I was dealing with what sounds very much like the same issue that I had several years ago, after several looks at the ecu under the trunk, I finally discovered that part of the leds could not be seen with the ecu totally mounted in place, when I moved it out I could see all of the leds and my problem with exactly the same symptoms was the crank angle sensor located under the timing belt cover. They are no longer available and at the time I bought a used one, and it has stuck with me thus far. If that is your problem, there is a method on the forum somewhere for using a sensor from either the 1500 or 1800, I don't remember which
