Hey everyone. So im swaping a b18a1 OBD1 in my 90 crx dx and i've just used my dx harness and followed directions for this website here, MPFI Swap. Its an MPFI swap so i just followed every single direction from that. Using a PR4 ECU. No check engine light is on, the motor is cranking, i am getting fuel, main relay is good, i am getting spark, just changed the cap, rotor, spark plugs and wires and still nothing.. checked all fuses. checked all grounds. batt started dying out so i re-charged it.. Theres a half tank of gas, theres plenty of oil. went over the wiring hella times, and everything is plugged in. Help please!!
