I have tried to pinpoint the problem but would like some advise. Let me start from the beginning. I was cruising in Fifth gear this past friday when all of a sudden the voltage dipped a little and then the car shut off. Tried cranking it would not start. I got it towed home and started poking around. I notice the fused labeled Fl AM2 40a in the front was blown. I tried replacing it, with the igition in the on position the fuse was ok but it popped again as i tried starting the engine. The ignition main relay clicks when you put the car in the on position, but the fuse label ecu-ig 7.5 after the relay is getting no power, which in turn goes to the igniter and then the coil pack. So im trying to pinpoint what could be wrong: igniter, coilpack, relay? I have included pic of electrical set up with some labels to give you guys a visual. Any feedback would very helpful. Also nothing is melted, wires to and from the harness look good.
