Engine seized? Check for loose or corroded battery cables Weak or dead battery? Flat spot on starter? Bad starter solenoid? Bad neutral or clutch safety switch? Bad ignition switch?
solenoid or relay switch
If your car works fine when its not cold and only wont start when its cold outside then its a bad solenoid and most likely the one that regulates voltage to your starter. This solenoid can not be replaced with out replacing the starter because they are combined. Unless you have a aftermarket starter that will let replace the solenoid without replacing the starter. So all you have to do is take it to a shop and have a new starter put in and your prob should be fixed.
Check the battery cables. If there is no corrosion and you have good connections, then the starter solenoid/relay may be at fault.
Low voltage. Clicking is the starter solenoid. Low battery on the good car, bad cables or a bad connection. If they are all good, then the solenoid may be bad.
Replace it with a new radio or use car insurace
Check the 96 Caddys starter solenoid. Also check the wiring between the battery and the solenoid for any breaks or loose connections.
if it does not turn over and no clicking noise but headlights on, check start fuse and relay if it doesnt turn over and clicks probable starter solenoid
"hot start" issue. Could be the solenoid, or starter itself.
you can tell when your breaks start to Squeak or the car wont slow down when turning
Solenoid
seized engine? defective or disconnected solenoid? starter not grounded? starter is engaging a damaged gear?
Sounds like you might have a bad starter solenoid. Test your battery terminals first to see if they are loose or corroded.
