Going to chek out my ignition coil packs with a multimeter. Anyone know what the resistance in ohms should be for a good or bad? I've tried searching and just get sites selling new coils. Called Infiniti and they said their techs would have to search online but cant do that at this time. Called some shops and said to look for any burning or bubbling. I've had code p0300 for about a year now. Thinking its coils or injectors

 

From the FSM,

 

So anythin but 0 is bad?

 

yeah. What i would do is measure all your coilpacks and see if any of them are way out.

0 means shorted, infinity means open.

Wonder if measuring the capacitance would be better.

 

Pretty much got 1.7 on 5 and one was 1.9

 

Measure the capacitance?

 

i dont think so. i just tested the 3 prongs on the ignition. should there be 2 reading for primary and secondary?

 

except zero means the coil is good as long as it has resistance (which means continuity). So 0 is bad, everything else is good.

 

Should there be 2 reading with the 3 pins? Primary and secondary?

 

so I got the p0303...went to check out the #3 coil...removed coil pack and smelt burnt wiring in the pack. probably obvious that it's shot because of the electrical burnt odor...but for ***** and giggles tested resistance....im not a pro...but good instruction taught me how to get this far. so I'm getting 1.62 1 to 2 pin....and 0 on 1 to 3 pin and 0 on 2 to 3 pin. just looking for a verification from someone that this is the issue. thanks
