Default Dyna 2010 starts and stops directly

Hi,
Had a slow starter so a change as for a new one but of course a new problem appeared.
It starts for a second and then dies instantly. All the lights and stuff seem to work, I can't see any error codes.
The first time after replacing the starter motor, it complained that the side support was down, it then disappeared and is no longer visible..
Could it be that the ecm, racetuner or something has been reset, corrupted after I disconnected the battery or ???
Have not experienced this before when just changing the battery.

Disconnecting the battery shouldn't affect the tune or ECM. Speaking of the battery, check both ends of both cables to make sure they are clean and tight. Load test the battery.
If the IAC is dirty it could cause the bike to die at idle. So could a fuel pressure problem due to a leak in the lines or regulator in the tank. You should be able to hear or see it when you prime the fuel pump. Test the fuel pressure if you can.

How long has it set doing this work? Do you hear the timer running the fuel pump on key on?

In this quote from you 'The first time after replacing the starter motor, it complained that the side support was down, it then disappeared and is no longer visible.

Where are you seeing that and what does the side support do?

If you crack the throttle about an 1/8 turn, will it run? May need help from starter fluid spray but be cautious of popping back at you.

If it will, need to check fuel pressure.

Thanks for your comments,
sorry, side support = Kickstand (bad translation from me) and it was on the ledwindow at the speedo.
Tried to open the throttle but its the same and repeatly, cranck for a sec and the shut down. Its really like as it was programmed.
Tried it several times until the battery was low. But its not a bad battery, lights are fine and respons are fast from the starter..
Will work on it tomorrow.

Your kickstand / jiffy stand safety switch is not working correctly. Needs adjustment, has come disconnected, or is bad and needs replaced. See diagram.

This part replaces 50278-08A.

I had the same issue on a 2012 StreetGlide with a 103. I was given a suggestion of crank position sensor, Replaced with no change. Ended up to be a corrupted FP3 Map .Hope this is helpful, Mine would run for about 2 seconds.

Thanks man, I found what you said and it makes sense.
Now the bike works if I fold in the jiffy stand. still dying when i drop out the jiffy which seems a bit wonky with the N gear in but at least now i have something to go on.
And if I can't find the fault, I can at least take it to a workshop

Thanks again!

Thanks all, I follow all yours advice. The jiffyswitch is the bad guy.

Wow. What a fix thanks to Coolbreeze. So, jiffy stand safety switch needs to be added to the call out on bikes that have it for engine stall after start.

Anyone know the year it and the netural switch started?

When it's right, does the stand stitch kill motor if not in neutral?
