Yesterday I changed my coolant bypass elbows. Before I started I disconnected the negative terminal on my battery. After I got done I reconnected the negative and now my car will not start. I tried to remove my key and it would not come out. It will not shift out of park. My security light is not on. Checked fuses and they are fine. My gas needle does not move when car in on position. My radio works, but no lights on inside. Also when the car is in on position I hear like a hissing noise and one click, but when I try to crank it, nothing. Any ideas on what is going on?

My headlights come on. It seems like nothing is registering in my car. Normally when I turn my key to the ON position it will give me a fuel range to empty but when i do it now it just gives me dashes. Its like that for all of the features on my dash. Could it be some with the computer in my car.
