What is the problem if when you turn the key over all you get is clicking on a 1990 Chevy Silverado 5.7 L?

Answer 1

The clicking is almost always the starter solenoid (also sometimes called the starter relay)trying to activate the starter. There are several possible answers from this point. 1. Your battery may not be delivering enough current to the starter. 2. The heavy cable connections (one or more of the following)on the + side from the positive battery post to the solenoid, from the solenoid to the starter, and on the - side from the starter to the engine block (loose mounting bolts), from the engine block to the frame, or from the frame to the negative battery post may not be clean and tight. Start with the battery and make sure it is fully charged. Then go over the cable connections as listed above. If all of that checks out OK. the starter may be bad. Good luck! my trucks doing the same thing its not the starter because i have already tried three new ones from kragens Depends on where exactly you are hearing the clicking from. Inside passenger side is more than likely the actuators that open and close the doors for your defrost vents for floor and windshield settings. They get stuck from time to time. If it is in the engine bay then it could be many things. First find out where bout it is, then go from there.
