I replaced the engine about a year ago and it would not crank or start. It had sat unassembled for several months. it had started before without issues. Since the new engine the battery has been disconnected. It does have a new battery and starter. All ignition starter fuses have been checked. I have checked every wiring harness. I am wondering if the security system has locked me out due to long periods of no battery power. There are no codes. No open circuits. Any help is much appreciated.
