Need help diagnosing. All of a sudden car only clicks when I start it. And it only clicks once. Battery checks fine and car wont jump. My question is: Is there a way I can test my started to see if it is bad? Or test the starter solenoid? I know on my 67 I can jump the solenoid with a screwdriver. Not sure if it is the same with a 5.0. 92 GT convertibe.

Any advice appreciated.

Here's a checklist:

Since some of the tests will bypass the safety interlocks, make sure that the car is in neutral and the parking brake is set. Becoming a pancake isn’t part of the repair process…

Check battery, terminal connections, ground, starter relay switch (also known as solenoid) and starter in that order.

A voltmeter is handy if you are familiar with how to use it to find bad connections. Measure the voltage drop across a connection: more than .5 volts across a connection indicates a problem.
See http://www.fluke.com/application_notes/automotive/circuit.asp?AGID=1&SID=103 for help


1.) Will the car start if it is jumped? Then clean battery terminals and check battery.

2.) Check the battery to engine block ground, and the ground behind the engine to the firewall.

3.) Jump the big terminals on the starter relay next to the battery with a screwdriver - watch out for the sparks! If the engine cranks, the starter and power wiring is good. The starter relay is also known as a starter solenoid.

4.) Then pull the small push on connector (red wire) off the starter relay (Looks like it is stuck on a screw). Then jump between the screw and the terminal that is connected to the battery. If it starts, the relay is good and your problem is in the rest of the circuit.

5.) Remember to check the ignition switch, neutral safety switch on auto trans and the clutch safety switch on manual trans cars. If they are good, then you have wiring problems. See http://www.autozone.com/images/cds/gif/large/0900823d80195963.gif for 88-90 year cars .OR see http://www.autozone.com/images/cds/gif/large/0900823d80195964.gif for 91-93 year cars. See http://www.autozone.com/servlet/UiB..._us/0900823d/80/1d/db/3c/0900823d801ddb3c.jsp for 94-95 model cars.

6.) The starter may be hung, loosen up the bolts that hold it on, and give it a good whack with a big hammer. Tighten up the bolts and try again.

7.) If that doesn't work, use a jumper cable from the positive lead on the battery direct to the starter post where the big wire from the relay connects. If it cranks then, it is the power wire from the relay gone bad. This will be hard to do, since there isn't much room to do it.

8.) Pull the starter and take it to Autozone or Pep Boys and have them test it. Starter fails test, then replace it. If you got this far, the starter is probably bad.

Check the GROUND!!!

I bought a new starter because I thought mine was bad a few years ago and it simply turned out to be a corroded ground wire. Expensive mistake.

Like said before, take a hammer and hit the starter a few times, give it a few nice wacks, if its the starter, it will start. If that dosent work check the other stuff mentioned.

Sounds like a loose ground to me, I had it happend just like Vipersix. The easiest way to check if its the solenoid or the starter is to see if you get any voltage to the starter when the key is in the start position. If yes, than solenoid is okay.

If you can hear the starter click out, then your solenoid is working. Its either a ground or the starter itself.

here's the easy way, if the car has change and nothing happens when you turn the key, jump the solenoid, if it works it's the solenoid....

im sure you are hearing the solenoid click. best way to check is to jump the solenoid with a screw driver and see what happens....if you dont have a multimeter
