s14 sr20 questions

about a year and half ago i swapped in the s14 sr20det into a s14 240sx. had it for a while then i was offered and good price and couldn't say no to selling it. then the kid blew the motor whithin couple months of buying it. so the guy let me buy it back for fraction of the orginal sale. swapped in a new s14 sr20 motor and having fuel issues. i have spark, good ecu, good fuel pump, cam angle sensor new, good maf, and only starting with starting fluid being sprayed into the intake. won't normal start. and kind of not sure what to look for next. any help would be appreciated, thanks.
