SOURCE: have 94 grand dam change fuel pump change presure regulater and relay pump stays runnig and car wont start

If by cranking you mean the engine starts then you are having fuel issues. If the car starts with starting fluid then you either don't have fuel pressure or the injectors are not opening. After starting with starting fluid does it continue to run until you shut it off or does it shut off on its own?

Either way you will need to install a fuel pressure gauge to make sure you have enough fuel pressure. If you do have fuel pressure then you will need to make sure the injectors are firing. There is a tool available called a noid light or injector pulse light. You will need to unplug one of the injectors and plug this tester into the connector. If the light flashes while cranking then the injector is being companded to fire. If the light does not flash then you either have a bad engine computer or a control module. More than likely it is the control module. The control module uses the input from the crankshaft position sensor to fire the coil and the injectors the module may be loosing the signal for the injector.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

My car stop running while i was driving it now it wont start

Look at the alternator to see if it's working. If it doesn't work you won't have enough power to keep the computer, the ignition module or the fuel pump going. If the battery is older than 3 years, you may have to replace it too.
