Engine Light On (well sometimes)

'99 road King... Stock engine, stock electronics (except power Commander), Stock EFI, True Duals Exhaust... nothing fancy. Turn the ignition on... wait for fuel pump to stop, engine (fuel pump light) light goes out, start engine. Start riding and a couple minutes later the light comes back on. then goes off. then back on... when it turns on it stays on for quite a while. Sound like a fuel pump issue to you? Bike doesn't miss a beat when I'm riding. Am I riding on borrowed time with the pump?

thanks

Have you tried to pull a error code off the bike?Directions to check for error codes can be found in your bikes service manual.

What you are experiencing is a historic code that is reappearing. As has already been stated, check the manual to see how to retrieve the code and see what it is. I am not sure how to get the code from your year and model. Someone else may be able to chime in.

I have a 2010 Electra Glide Classic... My Check engine light came on one day, so I pulled over and shut it down. Restarted it and it was off. Road a few miles and it would re-appear! A few days later, I was riding with some friends and they noticed my brake light was on. I had the brake light switch (rear) replaced, and it never came on again. Oh yeah, my cruise control stopped working because of that too. All is good now. It sounds like my ECM would recycle and it would reset and the light would come back on. As far as an error code, never looked for it. Just fixed the switch so I had a brake light to keep the fuzz off my butt...

I had the same problem with my 2006 Ultra. Both sparkplugs were replaced and that solved the problem. Good Luck.
