I assume the pump was replaced because it was getting power but no fuel pressure ? Are you still not getting fuel pressure ? Spark to the plugs ? Normal compression when cranking the engine ? Security light not staying on ?
Check your fuel pressure at the schraeder valve that is on the fuel rail. If you have fuel pressure, check for spark.If no spark, then ignition diagnosis is needed.If no fuel pressure, check for diconnected, or pinched wires, as this can easily happen during an engine swap.
when changing the computer you must first disconnect the battery if you fail to do so you risk damaging the computer and other electrical components. i/e fuses relays and circuit breakers.
Are you sure the filter was installed in the right direction ? On some models the fuel filter has an arrow marking where the front of the filter is supposed to point.
