Ignition Coils

Does anyone know if the Ignition coils on the 2.7, or V6 for that matter, act like christmas tree lights? If one doesnt spark the others wont as well? Sort of like a safety feature.

 

they are all powered by the same circuit referance volage in most cases. but to answer your question . one bad coil should not make the others quit.im guessing they are not getting the signal to fire either from the pcm,lack of power (bad fuse or broken wire),lack of ground, or cam/ crankshaft position sensor. also check the connectors to these.sometimes somthing as simple as unplugging them and pluging them back in will break the corrosion inside and cure the problem.remember mostl sensors run off of a 5 volt referance. not the full 12 volts.it doesent take much corrosion to degrade that voltage. also check your engine ground. an easy way to do this is to hook you jumper cables to the NEG side of the battery, and the othe end to a clean metal part of the engine. check for spark.if it sparks. clean your grounds and your good to go. if not check the above.
