You see the wire colors for the coil pack, if that's what your asking? The red wire should be primary voltage to coil pack, the other three wires are grounds for the coil, coils, a b c, one coil fires two plugs. I looked at info for 4.2L engine.
Looking under the hood, fwd, the rear bank of cylinders from left to right, 1 2 3.
The front bank of cylinders from left to right, 4 5 6.
Hope this helps.
You can try unplugging one of the spark plug wires from the coil pack and then touching it to a metal surface, you should see a spark. If you do then that wire and plug are good. Do this to each wire to check for spark. If they all have spark, ensure that they are plugged in the correct order. If they are you may have a faulty coil pack. You can pick one up on ebay super cheap.
if you receive a code indicating ignitial coil c secondary circuit this means a plug wire that connects your ignition coil pack module to a spark plug in the motor has come loose OR has become worn out
(not likely on '05 odel) or one of the coil pack modules has gone bad. If you recently had muffler repair work done, then suspect a wire has come loose and attempt to remove and reconnect each wire to the coil pack. If not, I would recommend replacing the coil pack module that's easiest to get to and testing the vehicle after replacing it. If that doesn't do it you will have to keep replacing until it starts running properly or you will need a shop manual to indicate which one is "COIL C". It's not very likely that a wire will be worn out based on the age of your vehicle, but heat from a motor will destroy a coil pack over a matter of several years especially if the coil pack is near an exhaust pipe or exhaust manifold.
There is a switch relay that plugs behine the ignition switch cylinder.You would have to take apart the dash console to take it apart to replace it.Also helps solve a few problem on the 2001 chevrolet impala, with heat gauage not working and a/c not blowing cold air anymore.Replacing it, should fix the problem with that.
