I'm wondering if a shorted wire to the fuel pump relay would impact the ECM and spark

Very unlikely. Inside the ECM there are different circuits and, I think, those two cricuits are different. Since you now know that the ECM is working, but still have no spark you should check for power to the coil. Altough is the same fuse for the ECM, make sure we have power to the coil. All green/white wires at the coils should have battery voltage.
