Battery box area wiring question

[datsun72z]

Hello all, Ive finished installing an SR into a 96 240 and the SOAB wont start! I can hear the fuel pump priming everytime i turn the key to start, getting plenty of spark but will not light off! Im thinking the injectors are firing because the plugs are relatively wet after a few turns but im kinda running out of ideas! On a "good" turn the engine will start hitting on a few cylinders but not enough to start/.... So any ideas? And i noted that after reading a buch-o-posts that at no time did i ever hook the upper(Main) SR harness into the original lower KA harness. not near the fuse box or anything. Should It? Im working with a harness that was cut and spliced before i got it so im at a loss.. Thanks DAN

Timing may be off, rotate the cas while someone else cranks it. Also the battery tray plugs need to be repinned depending on which SR is going into the S14.
