Alright i recently put a brand new JDM motor into my 91 g20, it didnt come with the distributor or anything like that so i used my old ones that i know worked before the motor blew. It turns over fine, but no spark, i tried another distributor, different sp wires, different coil, different plugs, and ive tested all the cylinders and i get nothing, the only code the ecu will throw is my water temp sensor code which i am aware of cause i havent hooked it up and im pretty sure that shouldnt keep it from sparking....:zoinks:I NEED HELP IM STUMPPED
