check for power ground and signal.
THE MARKS ON THE COILPACKS MEAN NOTHING!
you should have 12v, ground, and a pulse signal. you will need a good multimeter to test the signal. the coilpacks are marked with a +, -, and e. those do not mean 12v, ground, and signal respectively. rather they will be mixed up. get me? i have been through this on 3 cars with supposed coilpack problems. all three were bad wiring at the ecm killing the signal.
