Cleaned the battery terminals and checked that my grounding strap is good. And I replaced the ignition switch today and still the problem remains. I see that sometimes after I have removed the key from the ignition, some of the the diag lights still remained faintly illuminated like a relay or switch is not resetting. Other times when I turn the key I get all the diag lights illuminated brightly as if I'm getting full power and then when I turn the key to start the engine I just get a click.
