You can usually connect fuel injector harness by length of wiring connection at the injector. I strongly recommend the purchase of a Chilton or Haynes manual for this vehicle. The Code you have maybe a stored fault from a prior event. Stored faults must be deleted in order to view current status of ODBII (ECU). The manuals have wiring diagrams as well as a list of the fault codes.

That won't help. If firing good other cylinders, then the module is good. It could be an injector problem. You need to check the spark on #1. Make sure it is sparking good, then look for air/fuel mixture problem-bad injector or something else in that cylinder affecting the air/fuel mixture so it doesn't fire good. Maybe a valve not sealing- need a compression test to check that.

First of all, even though the Issue says Coil Pack, that does not necessarily mean the Coil Pack is Bad. It could be a Loose Connection, it could be a Bad Wire, it can also mean a Bad Spark Plug or fouled Injector but to answer your question...

The Coil Pack is located under the Plastic on top of your Engine and Directly connects to the Spark Plug. If I was you I would Swap the #1 and #3 Coil Packs and see if the Fault Code follows the Coil Pack. If it does then replace the Coil Pack. If it stays with the Cylinder, I would be checking the Connectors, Wires, Injector and Spark Plug.

Check the piston rings,are them plugs oily.

202 Injector problem #cylinder 302 misfire #2 cylinder bad fuel injector, wiring going to it. Your PCM could be bad I don't think so Check coil on # 2 firing. Check # 2 plug make sure gap didn't close when you put it in. Bad injector or Coil or plug

If you changed the plug, wire and coil and it didn't clear the misfire, then I would look at the injector. try switching it with another and see if the misfire code moves to the cylinder that you put the suspect injector in.

Vin "7" or '9"???if #4 is firing so is #1. they both fire at the same time. have you swapped the wire with number 4 or another cylinder? have you checked for a injector pulse on #1 fuel injector? Compression on #1 Cylinder?

you may need to perform a leak down test to the cyliner and maybe you may have carbon on that valve. make sure the new spark plug wire has the correct continiuty

I had exactly the same problem when I bought a ford pu last year for resale. 4 injector wiring lines were chewed through. I tried starting it before I fixed them, and it ran on the other 4... but it did foul the plugs that had chewed lines, so I changed them & that solved the problem. So if you have the right fuel pressure at the fuel rail, and your injector wiring has been done correctly, i would not buy new injectors until i put new plugs in those cylinders.

If the plug and coil are good and you have good compression you should probably replace the cylinder 8 fuel injector.
