while cranking using a test light, see if signal is pulsing on both outer terminals with connector unplugged.
you should get the same result on both outer connectors.
if not then do continuity check on the wiring to PCM, if thats ok then check the pulses at ECU by back probing.
you will find the ECU drivers have failed due to leaving a missfiring coilpack on too long and its fucked it.

totally what he said.if the three wires from ecu to coil pack are ok then the coil driver in the ecu is fudged.if it is and you replace ecu make sure you put a brand new coil pack on it at same time otherwise it will do the same thing again
