I was overheating so I went to change the thermostat and It was very difficult and I did something that now prevents the car from cranking or even running if I hot wire the starter. I have all the lights, and dash lights, horn interior lights but when I turn the key to start it I get nothing. No click. No turn over. I hot wired the starter to see if it would run, and it turned over but it didnt start. Any ideas on whats happening?
Also, it is locked in park.
