And if it doesn't, the problem is most likely fuel pump/fuel filter or ignition related.

If the vehicle will not start, pull air filter metal cover, pour very small amt. of gas into top of fuel distributor and try to start car. If it runs for a sec. or two, you have a fuel issue. If not, you have an ignition issue.
