RE: JDM trueno not starting. need help!
no rpm signal probably means the pickup in the dizzy is knackered, of you have a break in the cabling between there and the ECU (maybe where it runs through the timing belt cover). Can't imagine that the code 4 temp has anything to do with your problems.

No rpm signal also means no injector pulse. Some of the older ecu's also used the rpm signal as a fuel pump cut, so in a crash when the engine stopped the fuel pump would shut off as well.

Check the resistance of the coils in the dizzy pickup, should be 140 - 180 ohm.
