A few months ago my car was not starting. It would just click when I turned the key. I replaced the starter and it fixed it. About a month later, its doing the same thing! It was an autozone rebuilt starter, could it really have gone bad in month? I lost my reciept so i'm not going to get a warranty on it, so that pisses me off. Is there anything else it could be? If I push start it, the car runs fine and holds 12+ volts perfectly now matter how long i drive it, so its not the alternator, and its not the battery.:bang: :bang: :bang: :bang: :bang:

Could be starter solenoid as well. I bought a reman starter from Schucks once and it lasted only 1 week! So it is still possible to have a bad starter. You could pull it out and have it bench tested as well. Autozone should do that for free.:D

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. The clamp on with 2 bolts battery terminal ends are a know problem causer.

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 for help troubleshooting voltage drops across grounds.

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.

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.
 
Jrichter's my hero. Also Autozone puts your warrenty in thier computer. Remove it and get them to test it for free if you suspect it. Most likely you have a wiring problem (if it doesn't work it's open, if it's smoking or won't shut off it's shorted)

I've had a starter relay go bad on my merkur xr4ti, that was an experience!! Scared me to death because it just would not stop cranking and everything started smoking.
