On my truck listed above Lariat 4.6l triton v8. I have replaced the battery, starter solenoid, starter and ignition relays, and nothing has fixed my vehicle. It still continues to click when trying to start it. It has completely drained a brand new battery twice now. Please help me.

Good afternoon,

Does it go dead sitting overnight?

Did you make sure the engine turns? When you hear the click, is it the starter making the noise?

I attached a wiring diagram for you to view.

Check the fuse for starting. Fuse 21 in the under dash fuse panel. Check for power on both sides in the start position.

On these trucks the windshields leak water onto the interior fuse box on the driver's side and also can ruin the gem module that is bolted to the back of it. Have a peek under the dash and look for excessive rust and of course water drippage.
