Right on . The post did not specify if the engine is getting spark or if fuel pressure is found. Also, a noid light or computer safe test light should be applied to the injector wires to see if pulse is found. Lets hope the CPS is a quality part. Any trouble code AFTER part swap ? Being this engine is DIS , the cam sensor should be checked as you would even a distributor driven ignition.
Clean computer grounds and verify 5 volt reference at any sensor to ensure PCM communication .
what trouble codes were logged , if any before parts replacement ? But yes , start with the basics , fuses , sometimes the obvious is overlooked and you get lucky.
