SOURCE: No fire from coil to #1 cylinder
Ok since you did all that if you want to swap around fuel injectors taking note where you put cylinder 1 injector. Lets say you swapped it with cylinder 4 . Now if you get a different code say P0304 which is for cylinder 4 misfire then you know it is your injector at fault. These are wear items and should be replaced every 100,000 miles.
Also i would suggest if you dont want to do that is get some good high octane gas when you are completely empty and fill to 1/4 tank now put in Lucas Oil fuel injector cleaner and run the car till empty. Now fill up tank with high octane gas in see if this helps. Clear code after your second tank of gas and see if the code comes back. if code does pop back up then i would do the swapping of injectors as i stated earlier. I hope this helps and good luck with the diagnosis.

power not reaching cylinder 1 ignition coil. check electrical connections and wiring for any damage. test for power and ground at cylinder 1.
hope this helps.

Try the ignition module.This is more than likely your problem.It is on the coil pack where the wires connect to.I have had a few of these go on me.This should take care of your problem.Hope this helps.Good luck.
