All the lights in my car work, but when I turn the key, you only hear the slightest click sound. Ive checked the starter and it tested fine. This is for a 2002 camaro ls1 engine.
Check your battery voltage
If it's ok then there are three things that will cause this:
The security system - If the security light stays on then your key is not registering right with the ecu
The starter relay is faulty
The park neutral safety switch on the transmission is faulty
You have to check for these things in sequence before you get to the starter.
