There is no spark plug voltage when cranking
The power supply to the coils has no voltage during the cranking even with the
plug on there is no spark
Check your main power fuse under the hood. An see if it burnt.
The most common is a failure in the ignition switch, but 89yota is right also you should check the fuses, if you do find any that are blown then you need to find out what caused it too blow.
Yes one engine management 20 amp fuse was blown I replaced that one in the engine fuse box but still no spark
Does the battery power still go away when you put the key to the crank position on the coil power wires?
