so today was a beautiful day and I went to take the stang out, so I took the t-tops off then I get in to start it and nothing. when I turn the key it didn't even crank it just sounded like when power lines spark ...I don't know how to explain it just like a buzzzzz. I'm sorry its just I've never heard it do that before it was weird. like I've had the problem where it wouldn't start before but it would crank so that was a low battery and one time when it didn't do anythins so I changed the starter solenoid and it started right up but this time it was just like a buzzzzzzz.....so maybe you guys could help in this weird electrical problem I'm having..thanks a lot guys
car wont start????

Check the solenoid. If you can jump the two big lugs (E-brake on, being safe since the car could try to start in gear) on the solenoid and it starts, then try connecting the slide-on terminal to the battery lug on the solenoid. If it doesnt start in the second test, the solenoid could be bad.
If it does start in the second test, check the clutch safety switch for 12 volts out when the pedal is depressed, and 12 volts into the switch with the key to 'crank'.
Jrichker has a real nice post about testing the starting circuit - I know this was tough to follow.
Good luck.

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.

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.
