Coil Pac

[bigfoot2]

Hi all

tested my coil pack yesterday using a fluke 77 meter, got a reading 9.40k ohms on 2 & 3, 9.42k ohms on 1 & 4

took off the vehicle and tested it today now getting 10. 40k ohms 2 & 3 and 10.43k ohms on 1 & 4. i was not getting reading from 1 & 4 yesterday and put it down to a faulty coil, but i think it was my test lead.

are these readings within the ranges they should be, as i have no way of comparing them with original values.

hello again

ive been messing around with the car, trying to work things out and ive found that, all 4 cylinders have a nice blue spark,

but if i move the spark plug away from the engine about 1/ 1.5 inches away from the cylinder head, i find that i get a strong spark from plug to engine block. i tried this on all cylinders, 1 -3 fine, cyls 4 would only spark 1/4 inch away.

so im thinking my problem must be the coil pack, what i dont understand is if the coil pack fires two plugs at once then why arent both cyliders affected. cyls 4 is still the fault im getting on scanner, so i think i will buy another pack and cross my fingers it works. the car is like a kitten when idleing.

thanks all

if you are getting a poor spark to one plug and it is not the fault of the ht lead, spark plug or ecu it must be the coilpack.

 

i was sent down the wrong path very early in the diagnosis of a misfire because someone told me that it couldn't be the coilpack because of the particular cylinders that were misfiring.

good news. its a huge relief when you fire car up for the first time after changing the coilpack and it does sound like an old moped anymore.

Apart from sounding like an old moped what are the usual symptoms from a knackered coilpack just for future reference ?

misfiring, three cylinders in my case. no power, popping, cat glowing red from unburnt fuel.

 

firstly if you have the hardware/software you need to check if any error codes have been logged. then, you need to eliminate plugs, ht leads and any damaged wiring to the coilpack. if you still haven't got a healthy blue spark to all plugs you need to check for an electrical pulse from the ecu to the coilpack. if that is there then it is 99% certain that you have a faulty coilpack.
