When the engine is running, and a volt meter is placed on the battery, what is the voltage reading? This is the first basic step to check the alternator output. Do not rely on the gauge, use a volt meter.
Also rev the engine to approx. 2500 - 3000 RPM, what is this reading?
With the engine running, again, place a volt meter on the battery, turn on all the accessories, lights,blinkers, heater motor. etc. What is the reading when all these accessories turned on?

This could be a problem with your starter -- if you know a bit about engines try tapping the starter with a wrench while someone turns the key (not too hard so you don't damage it if this is not the problem). If your starter motor has a "dead spot" tapping it can get it to free itself up and might help. If this DOES help, please consider changing your starter so you don't have to keep going through this problem. If tapping the starter does not help, it might just be dead altogether. If you are doing your own work, try replacing it and hopefully that should help. If you are not going to do your own work on the car, a mechanic should be able to give you a proper diagnosis and repair the issue without too much hassle.
After you get it started check to see what the output of your alternator is it should be 14.4 volts if this is the reading your battery may be bad you do need a certain amount of not only voltage to start but also amps from the battery

Hi Joe, I am having the very same problem with mine, and was just hoping that you could tell me if you were able to get yours working again, and if so, what you did please?
