misfire on cylinder 1, 2006 5.4 f150
I originally had a no start and no spark issue, after replacing the #33 coil fuse I had spark and the motor would start and, I've since replaced the COP (coil on plug) the spark plug on the #1 cylinder, it made no difference in the idle or running. I can pull all the other injector wires off one by one and put them back on and it makes a difference in the idle all but the #1 cylinder. I checked and have great spark on all cylinders but #1 seems like it's not doing anything but sparking. Could this be a clogged injector? I've got a palse on the injector cables.

was over thinking the problem. Was a simple resolve in the end.
First I didn't have spark or power to the ignition coils, I changed out the crank sensor, resolved it by finely checking the fuse on the coil power.I had a code of 301 so I had a next door neighbor look at it and he had swapped number 1 coil with number 5 coil without telling me, this lead to additional problems in my trouble shooting. It ran but ran ruff so took off each injector on all eight cylinders one at a time to see if there was a change in the motor running. This showed the number 5 cylinder was not preforming. I had bought a new coil and plug to put on number 1 cylinder, I took the coil I pulled off number 1 and installed it on number 5. Problem was solved!!! I have learned so much from the people on this site, I want to Thank everyone that helped.
I plan on changing the rest of the plugs and coil over plugs.
