I also think it could be a sensor, but which one? Either that or a bad connector, another bad injector, bad ground or bad ECM. The list could go on and on.

While I was broken down I called the dealer and told them about no spark. They told me to pull the Crank Position Sensor and clean it in case it had some crap on it.

Even if you have spark, it may not be occurring at TDC on the compression stroke.( I'm not real sure about this but I think it's a possibility). Timing could be out in left field.

I've just about worn myself out worrying about it. That's the main reason I haven't put many miles on it. I don't like to play guessing games although I do appreciate all of the suggestions.

I do have a manual and will as suggested begin to check all of the connections to make sure they are good. Other than that, I can't do much of anything else.

With my limited mechanical and electronic knowledge of Harley systems, I can only guess at it and become a parts changer after all. That's if I decide to continue riding this bike.

Posted this in the General Forum the other day. Not saying this is the problem but I was always taught to rule out the simple stuff first. Tight connections, bulbs, fuses, whatever Thought this might be worth posting here too. They sorta know their chit over at AIM would not think this would slip by if not true.
"Read something in American Iron yesterday about starting on the new bikes here is the quote from Chris Maidas article. Hope he doesn't mind. "Did you know there's a sensor in the circuitry that will not allow the spark plugs to fire if the battery voltage, as you crank the electric starter, drops below 12 volts? The battery may indicate over 12 volts with no load on it, and the starter motor may even spin the engine over just fine, but if the voltage drops to 11.9 volts or less when you are cranking the starter, the ECM will not fire the plugs." Another case for keeping an eye on your battery. If it is suspect maybe a load test is in order. You might also try pulling the ecm connector and cleaning it. Cured a charging problem on my RK and some isuuse w/ other bikes. You could do a search of the General HD Forum and read whats there

Thanks vet767 for the input. As I posted earlier, I have had the battery load tested and it tested top shelf. I've cleaned the ECM connector as well as the battery connections. The only ones left are all of the sensor connectors. I've been looking at the manual and I don't think I can access some of the sensors without removing a few parts.

Thanks!

When it's cranking over and not starting, does it make a grinding noise?
