need help...
You need a special test light for the coils. A regular 12v test light will not work in most cases. You will overload the light and it will either blow or just not read correctly.
The reason I am asking is because, baring a lightning strike, all your coils do not go bad at once. And if indeed all the fuses are good and you have checked your inertia switch then one of two things is wrong,
You have a bad tester for the coils and this is actually a fuel related problem or
You have a sever in the lines to the coil or in the loom somewhere.

He only has 2 coils. It's an early 4.6l. 3 wires to each coil. 1 wire will be constant power, red wire. Other two wires should be PCM ground to fire the coil. Can be checked with a test light. Make sure you have constant power on the power side cranking. Check the ground trigger while cranking. If it lights up test light, should be sparking.
