2015 Iron 883 cranks but won't start
I rode this bike about a week ago. It ran ok although I noticed that when cold it would stutter just a little if I gave it the throttle a little too fast before it warmed up. I had been messing around with my V&H FP3 since I removed a set of Cobra mufflers and put the stock mufflers back on. I had it in autotune the last time I ran it. When I tried starting it today and it wouldn't start I put the stock tune back on the bike and charged the battery. The bike cranks fast but no start, I can hear the fuel pump running like normal. It has 7,000 miles, I changed the plugs about 100 miles ago. Looking for advice as to what I should check. Thank you

Is there any codes stored? Harley Trouble Codes (fuelmotousa.com)
I realise "messing around" is a technical term. Are you sure the ECM is out of auto tune mode? The FP3 makes certain mods that might affect starting.
Check with V&H on the steps you have taken whether that would leave an indeterminate state.
If you put back the stock tune and mufflers what about the air filter?

why? Sounds like its still in auto tune to me, and you can still get better performance even with stock mufflers using FP3, the bikes all run lean from factory.

I just sent an email to V&H tech support to see if they can help me rule out the tuner as the source of my no start condition. The only code that the tuner tells me I have is U0100. Reading on their website it looks like it's a normal code. I'll go back outside and try removing the tuner and see if disconnecting it helps.

Confirm it isn't in auto tune mode.
I guess you do that by loading a different map as I think part of auto tune is it modifies the map you want to base auto tune on and it flashes that to the ECM.

V&H just replied to my email and said that code says I have a bad battery. I guess it could be but I read the FAQs on their website before I contacted them and it said that code is completely normal and will not trigger a check engine light, you can periodically clear the code through the FP3 app if they occur. My code wont clear. Im going to head out and check the battery and connections now. It cranks fast so it seems good from that aspect.

I checked my battery and it reads 100% charged, 334 CCA and 12.81 volts. Looks like I need a troubleshooting guide ... I checked the spark by grounding both plug wires on the block, both sparked well. What next?

Yes, Autotune is off. I flashed back to the stock map and a previously used map as well. Today I will trace the pos/neg wires and make sure they are all connected well and clean. The bike cranks so fast that I wouldn't think the connections would be the issue but just to be sure...
