i have a 90 lexus with a 4.0 leter motor it has never failed to start last week i sent it for a full detail . saturday i went to start it and all i got was a clicking sound as if the battery was dead . i got my jump pack out to jump but i still got nothing but a clicking sound i also noticed that the detailer had the battery ends off and did not tighten them after i tightened them i tryed again still nothing but clicking . could the lose terminals have triggered something to cause this the security light is off . what could have happened and what can i check or do to get it running again . thank you for your input
