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.
use a screw spark voltage guage they cost 5 bucks ya stupid foctard
