No spark or fuel

I assume you've made sure the supply wire to the fuse box is in excellent condition. Have you double checked all your grounds? The two under the intake by the brake booster are very important for the ecu. Do you have fuel pressure?? You need to figure out if the fuel pump is not turning on or if the ecu is not firing the injectors. This will tell you where to look next. Check the cps wiring again. It gives information to the ecu for both spark and fuel. Use the tsrm diagram for reference if you need to. You need a multimeter or at least test lamp to trace power to and from the main relay, ecu, etc. etc... It shouldn't cost you any money to figure out whats not working, just time and patience... and a multimeter. Good luck.
