1999 Honda Civic Q&A

1999 Honda Civic Question: My car will not start or go into gear after replacing the radiator.

I just replaced the radiator and the sensor that plugs directly into the thermostat (don't know why I can't think of the name of it). And now my car will not start, or go into gear. When I turn the key to the "on" position, I do not hear the "click" from the gear shift after applying the brake. I checked all the fuses, and all look good. Any ideas?? -
Answer 1
Is the battery charged and hooked up? -
Comment 1
Yes, it is charges and hooked up. The lights and the radio come on and it tries to turn over, but I will not. -
Comment 2
Does yours have an immobilizer system and if so does the green key light on guage panel flash continuously? And as far as it not coming out of park , first easy thing to check- brake lights - if brake switch is bad it will cause that. -
