The first thing to check is the ignition timing then the spark plug gaps. There are specific settings/size for the above and must be correct for the car to run smoothly.

ok first shoot one little shot of gasoline in the throttle body or in the air cleaner to see if it will start up . If so it is a fuel problem .. Than I want you to try and turn on the Key and go to the rear of the car and crawl under the car and hit the gas tank as hard as you can with your fist.. this only sometimes works it might wake up the electric fuel pump and then try to see if it is picking up by starting the car.. also you might try it several times like hit it like your mad at it.. only use your hand not a hammer or anything damaging .. then try to start the car .. if it starts and runs you are soon going to need a new fuel pump... thanks jerry holler if you need more...

To check injector pulse, you need 2 people. One is to crank the engine. The other is to watch the voltmeter connecting to the plug delivering the electrical signal to an injector. If during a period of cranking, there is no voltage displayed that means there is no injector pulse. Here is an image of connector port going into the injector to open its valve as needed.
