I have a 2002 3.8 V-6 mustang it is not firing from the coil on 3 and 4 . I have replaced the coil pack and checked plug wires . Still not firing . I measured the primary side, pin 4-1 pin 4-2 and pin 4-3 about the same resistance,
measure from secondary 1-5, 3-4, 2-6 and there about the same. I cranking the engine, check for a pulse to ground at harness side of the connector to the coil. Pin 3 did not pulse so I ohm pin 3 to the computer pin 52 very low resistance. Do need to replace the computer? Thanks for the help.

Has 98000 mile
Same thing with old coil but I don't think its the coil because there are 4 pins that plug in to the coil pack pin 1 and pin 2 pulse my test light pin 3 doesn't and the wire from pin 3 to the pcm pin 52 is good.
I didn't change the plug this time because plugs and wires where changed last November
Nothing else has been done to the car
Coil brand was duralast
I don't have a electronics book for this car.
PCM has not been wet.
I have a motorcraft coil on it right now it is doing the same thing
It is not the coil because Im only getting a pulse on pin 1 and pin 2 not on pin 3 these are the pins that plug into the coil from the pcm and you should get a pulse on all 3
All the plug wires are in the right place.
