Hi everyone! I'm new to the board and have been trolling it for the last couple of weeks for some answers. As the header states, I'm reviving my Duc from 5 years of storage. But after weeks of troubleshooting I happen to think it's the fuel injectors that are giving me grief.
So first things first:
I removed the gas tank and replaced the fuel pump assembly with a brand new one. The gas had turned to varnish and clogged the old pump as well as deteriorated the hoses to a gummy like state.
I also cleaned out the tank and removed all deposits that had formed over the years. I also completely replace the fuel line. Oil has been changed out as well. I purchased a new battery and installed it, and now I'm into unchartered territory.... I turned the ignition on, all lights came on...I heard the whirring sound of the fuel pump priming and hit the starter button. The engine turned over but wouldn't start. I sprayed carb fluid into the engine and it fired right up for about 2 seconds before dying again. I'm guessing the engine is not getting gas.
So checked the kill switch...that was fine, and pulled the plugs to check for sparks. The plugs fired a nice white-blue spark. Then I went on to check the fuel injectors meanwhile checking to see if there was fuel pressure...and there is. I pulled the injectors and did a testfire into a glass bottle. Nothing. No gas came out of the injectors. :'(
I have a friend stopping over in an hour with a volt meter to test for juice to the injectors. I'm also looking at the igniter boxes as a possible problem.
Now I'm thinking that after all those years of sitting around, it's quite obvious that they can become plugged...so now what? How can I clean the injectors if that's the case? Can I detach the injectors and soak them in Seafoam? Has anyone tried this? I can always replace them..but I prefer that to be a last resort. Thanks in advance for your advise. I'll update in a couple hours.
I'm no expert on my Duc but I am also very willing to learn and do my own repairs. I just need to be pointed in the right direction

Last time it made no noise whatsoever! So this means that thes injectors still have a chance of working. I'm so pumped....now I wish I did both of the injectors at the same time...I would be listening to my Bella right now! . Thanks for the info Chromo! I'll update again tomorrow when I have both injectors done and installed.
