The usual fault is the module fitted to the top which stops comms between PCM and pump causing non start i.e P1664 'FIP requesting reduced fueling mode'. DI obviously is a rotary pump which supplies injectors with a timed delivery of fuel, injectors not fired electronically like you quite rightly say.
