If the car itself won't stay running, you either have a pinched fuel line or possible blockage. Is the fuel pump electrical or standard?

In ANY no start situation there are two possible causes.  Either no spark or no fuel.  I'd have to assume with a new fuel pump you are getting fuel at least to the filter.  To check, simply loosen the nut on top of the fuel filter just a little.  Turn the ignition key to on.  1. You should be able to hear the fuel pump hum for a second.  2. Go check the fuel filter where you loosened the nut it should wet with fuel now.  If not check to make sure the fuel pump is getting signal to work (voltage sent through the e.f.i. relay.  You can hot wire the fuel pump directly to the battery to see if it works.  If it does, check the e.f.i. relay.  It's located in the passenger compartment on the passenger side on the center console near the floor.  Remove the side panels from the console  You should see a silvery metallic "box".  Carefully unplug it and check the contacts for corrosion.  If you have a service manual handy (and you should always have one!) check the procedure for checking the relay. This relay controls not only the signal to the fuel pump but also the injector and the signal to the ECM.  New one should be around $100 from the dealer.  At least it is in Ohio.  Hope some of this helps.
