The three hot wires come from the computer with no splices except at the bulk head.
I don't see any other way to pulse the coil. If one wire pulses and the other two don't
but are hot it indicates all wires on the hot side are good to the computer. You may have a bad computer. I would pull the right cover over the timing belt and make sure its tight. If possible roll the engine over and check for a broken tooth on the belt. The cover has five bolts on my 2006 I pulled mine today for a no start. I had a bad fuel pump relay. You also have to remove a few other bolts holding brackets to remove the cover.
Remember a junk yard computer would be cheaper.
