No start issues 2011 Genesis need help!!!!!

[Arob1]

Hello to all, my Genesis will start up fine the 1st time but if I shut it off and try to start it back up the dash lights will flash but no start! I go to the trunk and take the negative cable off and put it back on it starts right up again just fine!
Taking the cable off and on is resetting something ?
Any help before going to the stealership will be greatly appreciated.

Things I would check:
1. Starter Relay, marked START in the fuse box right side of engine compartment.
2. ECU Relay, marked ECU in the same fuse box.
3. Engine sensor fuses (3 of them), marked ENG-SNSR-* same spot.
4. Immobilizer & anti-theft circuits, switches, fuses, etc.

IIRC there are not any circuit breakers on the car, but you might want to have a look at the fuses atop the positive side of the battery just in case.

Then unfortunately it's a trip to the best local automotive electrician you can find that's not at your local dealer. My best guess after the above is faulty ECU or BCM.
