I need my car working..TODAY, i've been trying all weekend to get it to work. I was driving it to school friday and it quit. I stopped at a light to let someone go and it just cut off. It cranked right back up. I drove another 100 ft and it shut off again except this time i had to coast to the side of the road. I tried to crank it again and it started after a couple times but only for seconds. Now it wont start at all. I turn my key and you here the starter but it wont roll over. I have replace the regulator, solenoid,alternator, and coil. We tested the spark plug wires by sticking a screw driver and in and trust me we had spark. I am getting fuel to the carb also. I even sprayed ether in it and it still wont even try to roll over. What could be the problem?
