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.

you can test the resistance across any two terminals of the coilpack. that gives you a total of 3 possible combinations. i dont know the specs but i can tell you this. the chances of you having 4 bad coil packs is pretty slim. check all of them and as long as they are all the same you are good to go. thats all i can tell you without specs.
