QuestionQUESTION: HI,
I have a code on my 2001 Sebring 2.7L sedan that is a P0354 which I have read on the Internet that it is the ignition coil #4 is this correct and which coil is it. Also if you would could you tell me the cylinder order on this engine like you are standing in front and facing the engine?
Thanks for your time!!!!!!!
ANSWER: Yes this is coil4 code. First check and make sure the coil wires or fuel injector wire don't have a little black tape somewhere on each one with a # in white thats what cylinder it is. If there is no tape then the best way I can tell you is which ever coil between the right head and left sits closest to the belts would be cylinder 1 then 2 would be the one on the other head in front then 3 would be back on the the 1st cylinder head just next position back and so on and so forth and that would be your firing order and I'm going to try to show you with this diagram I made each C will represent a coil and pay attention to what I mean by front of engine that is where the belts are B will represent the belts and the # will represent the # cyl
C1 C3 C5
B
C2 C4 C6
Hope you understand I tried

QUESTION: Thanks for your response!
Well we changed the coil, spark plug and still have the problem of
car missing on the same cylinder. We checked the wires coming from the
computer with a light tester(all we have no volt meter) and we get fire
there and at the coil and going through the coil. but still no spark at
the plug looks brand new still. We also check the fuel injector on that
cylinder and it was fine. Does it sound to like it is a computer
problem?
Thanks
ANSWER: I would check you cylinder compressions

QUESTION: Hi again,
Checked the compression already and it check great. But the problem is the spark plug will not spark even with a new coil and one that we know is working.
We are getting fire to the coil and through the coil just nothing comming out the spark plug on that cylinder. We have also tried a new spark plug. I think it maybe the PCM what do you think?
Thanks
Steve
AnswerCould be but didnt you say you had power on one wire going into the plug on the coil and with the car running I believe the other wire going into the plug on the coil should be pulsing ground I think I hope you understand what Im saying I am refering to checking the electrical part of the coil cicuit with a test light
Heres the test for that code out of a online service manual

Review the DRB Freeze Frame information. If possible, try to duplicate the
conditions under which the DTC was set.
Refer to any Technical Service Bulletins (TSB) that may apply.
Visually inspect the related wiring harness. Look for any chafed, pierced, pinched, or
partially broken wires.
