Just called but seems like someone was there but hung up.

Whats the best times to reach you EST?

Start by testing all fuses for power on both sides with the key on as a blown fuse is a common cause of no crank. Also check the inline fuses between the battery box and ECM.... Check your relays and the wiring harness for corroded or damaged wiring creating an open circuit. Test the IGN switch for power in and out in each position as well. Let me know...
