Hello, the vehicle is just silent when the ignition switch is turned to start position. I have tested the fuse and relay they are all working fine, I have tested the starter motor by connecting the solenoid wire directly to the battery, then the vehicle started properly. When I tested for power on the solenoid wire I could find any. I am suspecting the neutral safety switch but I need the diagram, that I may be able to by pass it and to see if there is any other things I supposed to check for.

Hello,

The safety switch is located on the side of the transmission. I have attached a picture for you.

Here is an article to test it:

Hello, I'm Danny.

Here is the transmission wiring diagram you asked for. This diagram is based on the 1.8L engine since you didn't include that information on your post. I've attached below and cut the pictures in half for you to view larger. The wires for the neutral safety switch are numbers 6-12 on the diagram that come from the ECM to the switch. I've attached them below again. Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is. Thanks again for using 2CarPros.
