Engine will not start..hear a clicking noise. NEED HELP!!!

I am trying to figure out the problem with my sons 2000 4Runner with the 3.4 V6 and an auto trans.
It will not start.
You can turn the key and all of the dash lights and stereo come on but it does not turn over all you hear is a "click".
I put a new starter in this morning and that did not help.
I put a new starter relay in this afternoon and that did not help.
The battery is fine. I tried the battery out of my tacoma and that did not help.
The auto parts guy said it could be the ignition switch?

Anyone got any ideas.

 

All signs point to starter, but you put in a new one...uuhhh

 

Id take a look at the starter you installed, make sure all the connections are good.

 

Have your battery tested, a bad battery does not have enough amperage to turn the starter over, so you will just get a clicking noise, but still have enough power to turn the lights on...

 

Neutral safety switch? Mine went bad after a dip in some water and all it did was click, try to start "N" if you have an auto trans.

 

Sounds like the starter. But check your battery first.

 

Is the shifter in park?

 

I'd check the wiring between the battery positive and the starter. The clicking you hear is probably the starter solenoid, which means everything else in the circuit (including the ign switch) is working fine. Unless your new starter is defective, it's probably the main power wire to the starter.

 

Replace the battery terminals, probably a bad ground like Whippersnapper said.

 

Starter relay?
Solenoid?

Sub'd for outcome. Good luck.

 

do u have access to a multi meter? stop buying parts on a whim. get u a way to trace the problem so you only have to buy one part. Sounds like a ground or a low amp in your bat
