Car wont produce a spark
 

Ok Im new here so excuse my ignorance lol ok first things first my car will not produce a spark i have tested the plugs distributor and wires in my buddies 92 lx and it ran just fine so no its not the spark plugs or the wires or the distributor i have run out of ideas as to what the hell is wrong with my car oh its a D16zc motor with everything from my d15b7 hooked up to it... it ran just fine and then one day i went out to go start it and it would fire up then backfire like crazy misfire until i let it high idle then it would be smooth and then it would just die once it got hot and now it doesnt get a spark at all. It gets fuel and everything just fine so its not the fuel either if someone could help me out it would be greatly appreciated i cant afford to drive my V8 around much longer
