Default Radiator/ starting problems

Recently I was driving my GTO and it started to over heat. I pulled over and when I popped the hood I watched coolant flow out from under the car. After I got it home and looked at it, it looks like it was leaking from just below the rad cap. I can see were the radiator is wet starting under the rad cap and going down and towards the left. I've read online that the GTO has a problem with the radiators cracking, but when I tried to start the car it won't start. It sounds like its trying by it catch. Im ok with replacing the radiator, but is my starting issue just because the radiator is cracked and not full? Ive nver had a starting issue until this happened.

This should solve your radiator problem and keep your engine cooler.

I had to replace my radiator cap a while back since it was not relieving pressure. But I only had the described issue of coolant leaking under the car, it was not overheating.

Radiator leak shouldn't have anything to do with your car starting.
