I have a new battery, all connections from the battery are good. When I turn the key on, all indicator lights come on, and when I turn the key to the start position, it will click in the control box one time under the hood. The starter does not do anything though.

Welcome to the forum, does the theft/security lite, stay on or flashing, when trying to start? Next, I'd check the circuits at the starter relay in the underhood fuse box. Voltage the load side of relay, terminal 30, is hot all the time. Voltage to the coil side of relay, terminal 85, goes hot with the key in the start position. Use a dmm to check for voltage.

The pcm grounds the coil side of relay, if no ground, I'd have to double check the security system.

Some of the national brand autostores will test the starter. Yeah, you have to take it off and take it to them. I'd still have to be sure the battery has a full charge and the connections are good.

I did check the security light, but it seems to be working properly. I am going to check the other now. Is there a way to bypass the security system? Thanks for the info on the relays.

If the security system is the problem, cranking the starter won't help. I can't help you bypass it.

I understand. I did check the battery, and it checked good. I went ahead and put a charge on it though. Thanks again for the info.

I have taken the starter off and had it tested. It was good. I show power coming in at the terminals on the silonoid, and main power cable from battery. After putting the starter back on, the car did crank two times with no hesitation. On the third try, it did the same thing, nothing??? after a few min. it cranked again. I changed the positive cable end it did have alot of corrosion. same thing. it cranks when it wants to.??
any more suggestions???

When the starter refuses to crank, Is the purple wire at the starter solenoid, hot? You have to test when the problem is ongoing.

If voltage and ground circuits are ok. The purple wire and the starter field terminal is hot, when the starter refuses to crank. Either someting is putting a load on the engine and starter, in that case, if you had the lites on, key in the start position, the lites would react if starter circuit from switch is closed. or the starter is faulty, don't care if you had it tested. Anymore the starter and solenoid is considered one unit. I guess I don't know how to help you, have a good day.
