I have an 08 Nightster with only about 2200 miles on it. I put 1000 miles on it then had the HD service done. After that I installed V&H shortshots, SE high flow filter kit, and a TFI fueler. Just last week I rolled the bike down the driveway to head off to work only to start it up and realize only one cylinder was firing. After some initial troubleshooting I found the following; spark is fine, does not seem to be getting any fuel into the cylinder. Checked all the connections between the TFI and the injectors and they seem fine also. LED lights are blinking which according to Dobeck is an indication of a bad wire. Seems plausible to me but I tried one other thing just to see if the injector was working, I hooked up the factory injector cannon plugs and it still is only firing on the rear cylinder. Also the battery is not holding charge well, have to charge it prior to troubleshooting or it won't start. Could the injector be bad so soon? Is the TFI defective? Any suggestions are welcome.
