With the ignition switch in the on position, use a voltage tester to verify power on each side of your fuses, replacing any fuse with power only on one side. Swap your relays one at a time with a known good one for testing purposes. Check between your battery box and your ECM for any inline fuse holders and blown inline fuses. Check for power in and out of your ignition switch in each switched position. With the ignition switch in the cranking position, use a voltage tester to test for power at the starter solenoid signal wire or S terminal. If there is power there but the starter is not responding, it's an indication of a failed starter solenoid or starter assembly that is in need of replacement or rebuild. Reply back with the results of these checks if any further help is needed. It is a pleasure to help anyway I can.
