Question about 1992 Mercury Grand Marquis
It can be several things. First, try unhooking and cleaning the Battery terminals and the Battery cables. Then reattach them and try starting your car.
If that does not work you need to test the Solenoid. Unhook the small wires on top of the Solenoid. Then take a Battery jumper cable and attach one end to the Battery cable nut on the Battery side of the Solenoid. Take the other end and touch the Terminal nut on the Starter side of the Solenoid. The Starter should spin. It will arc a little, but the engine should be cranking using the jumper cable to supply power. Remove the jumper and reattach the small wires.
Now you can diagnose the problem. Primarily you need a good Battery, if you could bypass the Solenoid and get the engine to spin at normal speed-the Solenoid is bad. If the Jumper cable really arcs and the Starter refuses to turn, the Starter is bad. If the engine slowly cranks with the jumper cable, the Battery is weak or bad or the Starter is dragging.
The click-clack noise you hear are the contacts inside the Solenoid. The Solenoid is the weakest connection between the Battery and the Starter. If either the Battery or the Starter is bad the Solenoid will make the sound. It does not mean the Solenoid is bad. The test I wrote about will verify if the Solenoid is bad when you bypass the Solenoid. You go on to testing the Battery and Starter with the methods I presented. It is really more simple to do than to write about.
