Hello and welcome to JustAnswer!

If there were an immobilizer issue then you shoudl see the immobilizer light either staying on solid or flashing during the no start period. If it's actually an immobilizer issue then it could be the immobilizer module itself or the key. If it starts after a key cycle it's less likely to be an immobilizer problem.

Do you see an immobilizer light flashing or staying on solid when this happens?
