Okay so I've dropped a ls/vtec into a 89 crx Si using a obd1 setup. So I've got the obd0-1 ecu jumper, p28 ecu and all the sensors. Yes I'm using the stock harness with the addition of the extras that I need. And the motor is not firing up. So I've narrowed it down to one thing, no spark. I have gone through all my wiring to check it and it looks fine. The coil is receiving the 12+ volts The entire ignition system has been replaced with new stuff that includes the entire new distributor, cap, rotor, wires, plugs The battery has juice. The motor is cranking (not seized) so yes the rotor is turning. Ive even tried connecting back my pm6 Si ecu and still no spark. Whats could be my problem?
