Wont start or turn over just replaced the stater and still nothing

Does your key switch work good? Do the warning lights and gauges on the dash all turn on with key in on? That verifies the ignition switch has power. If not, check fuse #9 in the Power Distribution Center (under the hood). It is a 30 amp fuse, providing power to the switch.
Are the battery cables clean and tightly connected at the battery and starter and the battery ground connection?
There is an Engine Starter Motor relay in the Power Distribution Center, the only thing between the ignition switch and the starter. With key in start, power is sent from the switch to this relay, and if relay is activated by the PCM (engine computer), then power goes on to the starter solenoid on the starter, and starter should then operate and crank the engine. If you have a voltmeter, you could do some tests for power at the terminals the relay plugs into. There are only 4 terminals. Post back with comments, or if you need help with testing those terminals.
