96 ka24de swap to 92 s13....need help!

[ShouldaHadaV8]

The car already had a 96 motor on a 92 transmission..so I bought a new motor after spining a rod bearing. I swaped the motor using the 92 distributer, ecu, and made a hybrid upper intake manifold. The car gets spark, and is properly timed, my fuel pump is not getting enough power but does work .need wiring help, and intake difference knowledge.
