6 bad coilpacks ?

[winreboot]

I just need some verification from some one that did resistance check on their coilpacks. To check them all you do is follow the manual right?

Over night all 6 coilpacks went bad !!!!! Temperature outside was in 40's raining cats and dogs and the next day it was 19 in morning. I think the moisture in the air got trapped in coilpacks and froze them up or some think. I remove all coil packs and they look little swollen. Resistance on them is 0 for all six. Car does not startup at all. Last year I check them for other reasons and they wore 1.1. How can it be that they could go bad?

Thanks,
Dave

Check your meter,The odds of that are very small.

1. What method is used to check the coil packs? Ammeter? Voltmeter?Ohmmeter?

2. Very cold temperatures do mean lower resistance as in superconductivity type effects..... however those are VERY low temps.

3. I just had all 6 replaced on Wednesday ($700 total) and my mechanic says there's no way of checking the resistance unless they're at operating temperature and that means either heating them up by operating the car (or oven????).

4. Did an MIL code for misfire ever trigger?

5. Dead start, I wouldn't know much about.A totally dead coil pack could be a possibility but could there be another cause? (If you knew that you wouldn't be f******** with the coils aye and you wouldn't be asking in this thread.)

I've never seen any Acura have all the coils go bad at one time. I'd be checking other things.

Could be a fail main relay. Cheap fix. Good luck.

I think he meant they have to be measured at a certain temperature because that's the temp the specs are published at. Regardless of temps, the primaries should never read 0, and a little variation in temps won't make that big a difference. I agree it's probably something else. Check the meter. Make sure it's on ohms and that's it's scaled right at the lowest number greater than 2 ohms. Meter battery needs to be good too. The odds of 6 failing overnight are probably less than 1 in a billion.

Hold the test leads together and make sure the display reads 0 Ohms, then check them, follow the procedure for testing Primary and secondary..report back..

Oh and for your own sake, GET A GARAGE TO PUT THE CAR IN WHILE NOT IN USE!!!:tongue: :tongue:

NSX?,... outside?...In the rain?,....In the cold?,.......I think I'm gonna cry:frown:

All six going bad is not likely. Not to mention from cold weather. If they were bad, if I remember correctly the resistance would be extremely high, not 0. Check your meter, and possibly keep your coils inside for the night and check at room temp?

Take your meter to Radio Shack a measure a few resistors they have in stock.

I suspect your meter can't measure small measurements and/or the input selector is not working properly.
