2010 1.6 aveo, how to test coil pack using multimeter

[davalc89]

Hi,

I have a P0303 misfire cyl 3 code on my vehicule. I swapped injectors and spark plugs to no effect. I have access to the electrical schematic for the coil pack. Even when a try to check for any resistance between power and individual coil wires, theres no resistance.

Thx

I've checked for fire on the spark plugs. I moved the spark plug to all 4 boots and there is fire. Hard to sell what is a good fire but there is fire. The car idle supper smooth but stumble on acceleration. Even after moving parts around, keeps coding only on cyl 3.
