No Power From Coil Pack On 2 And 3

[scottclarke25]

hi guys ,

im new here so please forgive me if you have answered this question before .

 

my car is 2001 Y ford galaxy 2.3 dohc 16v

two months ago i had to replace my coil pack as the original one died .

then the other morning i started my car up and it was making the same noises and only sounded like it was running on two cylinders so i arranged another coil pack to try , the new coil pack did the same thing . a friend said to me " take each plug lead out of the coil as it runs " which i did and it seemed as though no's 2 and 3 have very little power output ( not enough to create a spark ) ......... i tested them with a multi meter and there is a little trace of power but nowhere near full .

i was also told it could be the mass airflow sender unit , so i unplugged that whilst running and it made no difference but when i took the unit out of its housing the car cut out ( leaving me thinking that it was ok and not the problem )

i have now run out of ideas and im waiting for my diagnostics reader to come but need to use the car for work ( even on 2/3 cylinders )

 

what i want to know is ,,,,, has anyone on here had the same problem ? or does anyone know what the problem is ? or any more possible theories ?

 

( i started with a full head of hair and have pulled most of it out ) :) :19: :29:

Have you tried swapping HT leads/spark plugs around to see if the fault moves with them, or substituting with spares if you have them or you could buy one of each and try in each pot. Not sure how your testing HT output with a multimeter, HT voltages run into 10's of thousands of volts?
