I agree with the anti-drainback valve leaking diagnostic. When it leaks, it allows all the gas to drain down out of the fuel injectors and fuel rail and back into the gas tank. The long start time is how long it takes for the fuel pump to get the fuel back up to the injectors where it is supposed to stay even after the engine has been shut off.
That valve is located in the fuel regulator/pump assembly that is mounted in the gas tank so the tank would have to be dropped to replace it. You should be able to find a replacement regulator assembly on eBay.
