Turn the ignition key and I get nothing?

This sounds like the starter is having problems or the battery needs to be load tested these guides can help us fix it.

Please run down these guides and report back. I'd make sure the battery has a full charge and the connections are good. Next, I'd check the voltage circuits at the starter relay, in the power distribution center, under the hood. Also, your theft/security system might cause an issue? Did you try cranking in neutral?

Hi and thanks for using 2CarPros. Com.

The key does have a transponder in it, but the anti-theft or security light will flash or illuminate if the transponder is bad. If that is not happening, I question the ignition switch itself since you mentioned it catches at times. First, the ignition switch is not part of the cylinder where the key goes. It is an electrical device located in the steering column. There is a shaft which is moved when you turn the key which engages it. I hate to suggest this and be wrong, but you may want to inspect it to determine if something is loose and not allowing the shaft to properly engage the switch.

Here are directions for removal and replacement of the switch. I am not saying to replace it, but the directions show how to access it and work on it. The attached pictures correlate with these directions.

IGNITION SWITCH REMOVAL

The ignition switch attaches to the lock cylinder housing on the end opposite the lock cylinder.
1. Disconnect negative cable from battery.
2. Place key cylinder in RUN position. Through the hole in the lower shroud, depress lock cylinder retaining tab and remove key cylinder.
3. Remove upper and lower shrouds from steering column.
4. Disconnect electrical connectors from ignition switch.
5. Remove ignition switch mounting screw with a #10 Torx bit.
6. Depress retaining tabs and pull ignition switch from steering column.

INSTALLATION
1. Ensure the ignition switch is in the RUN position and the actuator shaft in the lock housing is in the RUN position.
2. Carefully install the ignition switch. The switch will snap over the retaining tabs. Install mounting screw.
3. Install electrical connectors to ignition switch.
4. Install upper and lower shrouds.
5. Install key cylinder (cylinder retaining tab will depress only in the RUN position).
6. Connect negative cable to battery.
7. Check for proper operation of ignition switch and key-in warning switch.

This is rather common on all car brands. Start by following the smaller battery positive wire to the under-hood fuse box. Check that connection. You may need to shine it up, then be sure the connection is tight. Also follow the smaller negative wire to the body and be sure that connection is tight and not rusty. This guide can help us fix it

Please run down this guide and report back.

Ok I have adiagram now check fuse 9 under hood then where yellow wires enter should be on when you go to start then brown wire is activated for pcm finally to starter. If you hear clicking at the starter hit the body of starter with a hammer if it starts you need a starter.

Have you checked if you are getting power to the starter solenoid when the key is in the start position? It is the smaller wire on the starter which only gets power when the key is in the start position. You mentioned there is power to the starter relay, have you tried a new relay?

Also, make sure the grounds are all good to the engine block from the battery. Based on your description, it does sound like a grounding problem.

Here is a how to for checking a relay:

If there is power to the relay, we need to check if it is getting to the starter. If it is not, there is either a wire issue between the two or a ground problem. Do me a favor, check continuity between the battery ground and the engine. While doing that, move the main ground wire around to see if there is any disruption in the connection. Other than that, we need to check power at the solenoid.

Anything is possible. Keep in mind, if there is power to the solenoid (smaller wire) when the key is in the start position, the starter is bad. If there is no power, you will need to trace that wire back to find where the open circuit is. I assume you tried switching the starter relay with a different one with the same part number.

Can I ask if the security light is flashing while you try and crank it over?

We are loosing power somewhere here is a guide and a starter wiring diagram so you can test where the power is being lost.
