Ok so i go to start my car the other day and when i turn the key all of my accessories have power but i notice that 1. i dont hear my fuel pump, 2. my afc wont turn on, 3. i dont hear the main relay click, and 4. the car wont even try to turn over. I have checked just about everything so far, the ecu is fine, i replaced the main relay, checked all fuses and grounds, and the ignition has power to all of the wires. this has all of my friends and myself stumped so any suggestions short of taking it to an electrical specialist is very much appreciated.

 

try relaceing the ecu fuse under the hood, mine did the same thing.

 

alarm?

 

try checking the ground wires that are connected near the thermostat. those groundwires are connected to the wiring harness and if it is loose, it will sometimes cause your car to do that
