What are you driving ? A beamer ?
Fill you info in if you want help. The part you skipped in your profile. Model year engine size. Don't just post either - Filling in your info provides us with the Model year and engine size.
Look at the top right corner in this post, That's what needs to post when you do.
Do that and I or someone else will help .

sorry about that i wasnt thinking about putting model info in there since i dont drive a ford im working on a friends F-150 4X4 with the 5.4l triton in it. ok a little more info than i posted earlier. since last post i have found that coil c is the 3rd coil from front on the passenger side of engine. i swapped this one with the #1 coil and still get the same code and miss. now this leads me to believe it is in the wiring of the truck. so what i need are the test procedures for this. or a link to a downloadable FSM so i can get the info i seek.
again sorry for the lack of information in the first post and the somewhat ignorant question asking for test procedures for the coils on this truck. I am not farmillar with ford engine management since i own a nissan titan and my software for reading the computer in that truck will not work with the fors since it is for the nissan computer only. thank you for your help and patients.

i know which one has the problem it is coil c (#3 cyc) third one back on pass side. what i really need is an ecu pin out or a link to a downloadable factory service manual so i can test the wiring form the coil to the ecu since i have changed the coil with a known good one.
That's what I was going to say. Definitely not the Coil or Injector. It's in the harness. Look down by the AC accumulator first. Make sure the harness is not contacting the top of the accumulator - If it is , pull it away and give wires a visual for apparent damage. Then tie the harness away from the accumulator. The MAG field creates havoc on our Ignition systems.
You won't get a SM download anywhere. ALLData might provide one , but you need an account. Hang on , Ill thro in the Ford Service DVD for 02 and see if I can find that particular pin - If not, PM me your email and I'll send you the file on that model.
I should have something by 6pm.
BTW - You should have pulled the plug by now right ? Your PS codes are wrapped with that DTC. So a plug check is warranted. Also post the manufacturer's name on the plug - you can check Secondary w/replacement or good spare connected to the coil/determine Primary Failure (true or false) until I find the pin local. The Plug needs to be inspected anyway.

I would install the right plugs first . Honeywell/Autolite DOES NOT make a spec plug for that model/stock. If Bosch plugs were installed - Then I would check the compresion in # 3 . Bosch plugs can and have compromised the motor in the past. They fall apart inside the cylinder and guess where the pieces go ...
This is Ford engineered motor, so the safest bet is to use what's speced for the truck.
Pick up a set of Motorcraft (Honeywell) Plugs. When people use the wrong parts and when things go wrong , they wonder why

i used what the owner brought me man so im have to use the parts given if the guy had given me the bosch i would have recomended against it and if the owner insisted would have put them in his truck anyway it is his truck after all. now let me see if i am reading this chart right the coil driver wire is the 4th over from the bottom right of connector c correct. well im going out to the shop to see what i can find on this thing.
also where does the start run wire go back to does it go back to the ecu or to the cabin harness or a relay somewhere?

well found the culprit it was the CD circut thanks jbrew it was broken right where you were saying on top of the accumulator. in working on this thing im of the belief most of the ford engineers should be shot in the head twice for some of the boneheaded component placement. just a slight rerout of that harness would prevent this prob
