Hello! Welcome to justanswer!
What is the eighth digit of you vin number?
The 8th digit is L as in larry. Don't know if this makes a difference, but this is a suv that belongs to a fire department.(may have a police package) Oh ya, i made a mistake, its an expedition not an explorer.
i'll get back too u on that
all right. i a little bit forward too. ur original question, the answer is yes. new coil to #3 coil this time and in-line-spark checker lit up. ( so new coil is good. and obiously #3 coil wiring is good.) which leads me to my next question. we checked for voltage at all coils on that bank, 1 wire in each of them has 12v w/ ignition on. the other doesnt and we tested them to see if the went to ground w/ an ohm meter. (it read open.)
Ok, at #4, what is the voltage to ground (engine block) with the key on for the red wire?
Ok, see the file below:
