Bad coil pack on crown vic

We think the coil pack is bad, but how do we test it to make sure? How long do they usually last? And what is the primary and secondary resistance supposed to be?

Well if you have checked the spark plugs and they look good then its probly the coil If the plugs have never been replaced i would start with a tune up and see if this fixes the problem. If not there is no good way for you to test it you would need a computer to hook up to the car

Test coil pack


You can test the pack. Not sure what the tolerances for this particular pack are, but the Primary should read in the .3-.9 ohm range and the secondary usually usually 1.0-9.0 ohms range. If you get some resistance at all, it is likely not bad. If there is zero resistance at either primary or secondary, it is probably bad and needs replacing,

My 1996 Crown Vic. recently started to buck and backfire a bit, turned out to be a misfire on #4, have been looking into it with a bit of progress but not complete success


I have faced the same thing with my car, this is not a single answer to this problem. It could be a bad boot on the coil pack, it could be a improper coil install, sometimes the spring does not sit in well, it could be that the intake manifold is leaking, it could be that the egr valve is stuck, it could the exhaust manifold is leaking, sometimes these issues are not caught by the OBD 2 sensors, you can try to move the coils around to see if that works out.

P0307 code on a 2005 crown vic


Cylinder misfire on #7.could be bad spark plug,or bad coil.try replacing coil and plug at# 7. It is the second last plug on the driver's side. If you pull the coil out and there is antifreeze in the spark plug hole,you may have a bad intake gasket or cracked intake manifold and the antifreeze is shorting the coil out. In that case you may have to replace the intake manifold.

I have a 1996 crown vic i need to know these trouble codes po301 po304


PO300 Codes-- are cylinder misfires

PO301 thru PO308

Last # is the cylinder

Could be bad ignition coil for a cylinder
or a coil pack for that side,depending what
engine you have

#1 &#4 are at the front & back of the passenger
side of your motor or firewall side if transverse

You will need to provide details of who worked on it
& exactly what was done besides replace a coil based
on a code

Codes aren't very good with COP Ignition but a complete
coil pack on one side should take care of some issue

Vacuum Leaks & other items can cause misfires & the codes
don't tell you to replace ignition parts as you may have

My 2002 crown vic started backfireing then would not start seems to not be getting any gas could this be my coil pack?


It sounds more like a timing belt has failed.
check for spark at the spark plugs
If there is no spark you can have the coils tested
But i till think timing belt due to the back fire and then the no run
If this was helpful please rate this question
