Two things that will make the car start. Fuel and Spark...cant have one or the other, must have both.
Since you've already done spark plugs, you have a few more areas to check around to see if you are getting spark. You should change your wires, dizzy cap, rotor, COIL. 90% of the time ppl dont get spark is because of the coil. In a worst case scenario, your whole distributor is bad....not likely though.
When checking for fuel, make sure your fuel filter is good, fuel pump, main relay is working, all fuses. Also, make sure your injectors are not clogged, and seals are all good. Others will fill in, Im tired.
