How do I check the ignition switch? If it was the ignition switch wouldn't it not crank at all? It does turn over fine, just no spark.

Yes, I've checked every fuse under the dash and under the hood. Unless, there is another fuse box somewhere I've checked them all; I've also swapped the main engine relay, alternator fuse, ignition relay with my running 92 but none of them fixed the problem. I found somewhere else that the ecu might need to be flashed into relearn mode and it may not be recognizing the key and causing it to not give any spark...does that seem right?

I've replaced the cps with my running 92 and still did not work, when i pull the codes i get 13 and 14 sometimes or the light will stay solid.

I have a 94 LS400 and i'm getting no electical ignition in the car. I swapped the ignition coils and no spark still i swapped the igniters and still no spark. I got a new ecu for the car and still nothing. does anyone have any ideas of what would have caused this? it was all of a sudden the car ran perfect then nothing...
