no spark in start

if you have a 4 wire ECU run a jumper wire from battery + to the wires on the side of the ballast resistor that provides voltage to the ECU and Coil, that will bypass the wiring from battery thru firewall to ignition switch back thru fire wall and thru the ballast resistor. If it starts and runs you know where to start backtracking from. (I would disconnect the same lead from the ballast resistor while testing as a precaution)
