P0351 - Wiring test?
Hello fellow F150 owners,
I recently did a timing job on my 2004 SCREW 5.4 and now i have a constant misfire on cylinder 1. I have replace the plug and tested 4 different COPs which made no difference at all.
Considering it is a constant misfire im starting to wonder if the COP is getting any signal at all (maybe pinched or broke a wire during the other work i was doing, especially as the wiring is getting a bit dry and crispy) but im not sure how to test for this; can anyone give me a step by step guide?

OK, I may have found a newish/used wiring harness but its not in the same country as me. Is anyone near their truck or do you have pictures of the PCM to check the number of pins? the seller is asking me to check but I'm nowhere near my truck and I cant find a decent picture anywhere. A good pin out diagram would be good if anyone has one
