"Problem was ....car would make clicking sound when turning key but would not start. All lights and radio came on. Shop said that it was not firing up and the starter and battery were fine."
Ok, now I have to ask............
How exactly did they determine that the starter was ok, if it wasn't cranking the engine over?? Did they pull the starter to check it?
This shop is beginning to sound less than favorable.
If you can't get the starter to spin, you cannot confirm it isn't the problem.
I'm afraid to even ask how they determined the battery was good.
The starting system on your vehicle is the basic of basics. This is first year apprentice stuff. Determining the problem should be relatively simple if one has his hands on the vehicle.
All fuses should be checked.
All fusible links should be checked.
The solenoid/relay should be checked for power in and out and the signal wire (small wire) when key is turned to start.
Power to the cable, as I mentioned earlier.
On the starter, there is One large battery cable.
With the key to start, the large wire should have 12+Volts. If it has more than 12 Volts, then the circuit is working.
All that leaves is the starter.
Simple battery and circuit test (this is a quick check and not to be confused with actual diagnostics)
Check voltage at the battery with a voltmeter. Is it more than 12Volts?
Yes, then keep the meter on the battery, have someone turn the key to start, does the voltage drop more than 2 volts? Yes, then the starter is drawing power but not turning.
Pull the starter and have it bench tested.
No, then power is probably not getting to the starter.
Sorry for the book I just wrote. : )
