I tested the IAC input with a noid light. The noid light flashes with engine running. Lights turning red and green if throttle is varied. Noid light does not flash when key is turned to on position. Also no flashes when key is turned to off position. Noid lights stay lit but don't flash either in "on" position or " off " position. Looks to me the ECM is not running the software routine to park the IAC for cranking? Comments please.
