Seems like you have checked and/or replaced everything. Do the old fashion test on it, while cranking spray starting fluid in to intake manifold, if it does not try to start you can suspect the ignition system. So check 40 amp fusible link (hot all the time) then ECU # 1 20 Amps fuse (hot with key on) check ignition relay. If the car tries to start when spaying the starter fluid into the intake manifold, then suspect a fuel problem. Check fuel pressure if pressure low, check fuel regulator, if regulator good then check fuel pump. Fuel pump should prime the system when you turn on the key..it should run for about 5 to10 seconds, if you do not hear the pump priming then turn key off for a few minutes and try again. If you do not hear the pump at all check ECU B+ 15 Amp fuse (hot at all times) and the fuel pump relay, if good suspect that you have a defective fuel pump. Make sure spark plug wires are plugged correctly. Good luck.
