The EGR has nothing to do with the fuel system. More likely is that your Inertia sensor has cut off the power to the fuel pump. This sensor can be tripped by a door slamming at the right frequency. The reset button is on the part and the part is usually around the front floor kick panels or in the trunk, especially on cars with Air-ride.
Check pictures from parts stores to see what you are looking for.
It is possible you have a leaky head gasket, allowing combustion gases into the water jacket. If this is bad, you will see white bubbles in the coolant, like dry ice, but not in every case.
There is a test for this condition you can have done

It is possible either or both are bad. You can get them checked free at most Autozone, Oreily,or Advance parts stores.
Your old units should have been checked before you bought new ones. The problem, if both new parts test good, would be the wiring in the car. Make sure that you connected the wires when you installed the Alternator.
Tip****The plug in Alternator wire which has the small wires going into your stem tab has a habit of riding up the plastic plug and failing to secure the wires to the tab. Make sure your battery ground cable is disconnected, then try to slide the wires out of the plastic clip and directly attach the wires to the Alternator tab. Then slide the plastic plug and lock it into the Alternator housing. Reconnect battery ground cable.
Check the battery cables and engine to chassis cable for voltage drops. You have either a cheap crappy rebuilt alternator or a problem with connections causing the alternator to go bad. Make sure the battery is tested properly.
it can be the connector in the unit. you would need to open it up and re solder the parts back on, it dont take much for it to come away from the board. being dropped bumpy road.
