So I have a 89 crx hf body with a d16a6 bottom end and d16z6 top end I have converted to obd1 from obd0 and have a p28 ecu my crx is cranking but isn't starting I'm not getting any spark but I have pulled my distributor off and put it on my friends civic and it is all working and all the wires on my crx are all good I have no cut wires and getting what they are suppse to get I am thinking I have a sensor unpluged or broke and the ecu is keeping the car from starting so I am wanting to see if anyone knows how to pull the codes scince it is all the obd0 wireing so if there is a jumper that I haven't found or what I need to do.

 

jumper should be at the driverside shock tower. trip the 2 wires and the cel on the gauge cluster will start blinking if you have codes.

 

i second that motion!.... ounce you find out the codes youll get a better idea of what is going on
