does anyone know the best way to check the ignition system for spark
with coil on plug ignition? you can't just pull a plug wire and stick
a spark plug in it to see if you have spark.
i am guessing a code reader will be necessary, without taking a fuel
rail off and removing a coil to check for spark. i realize each coil
has a low voltage and a ground to it. that would just verify you have
a pulse from the control module right?
I don't understand, why can't you pull a coil pack, jam a spare plug in
it, and watch for spark? You can use any regular spark tester on COP,
as far as I know. You can also measure the resistance in the pack just
like a distributor or DIS system, you just have to do for each pack.
