Coil pack only firing 2 cylenders
I'd add the information on how to test the coil packs yourself to make
it a more complete thread...
How to verify if your coil packs work!
Engine worked with: 1996 maxima
Requires: An ohmmeter (cheap purchase at radio shack....)
Conditions: Make sure your engine is cold, or it'll be hot on your hands
you have 6 Ignition coil packs. 3 up front and 3 near your firewall.
(when asking for new ones, they are referred to as L and R)
3 are hidden behind the plastic piece on your engine that says NISSAN...
simply remove the bolts and remove the plastic piece.
once removed, you should see 3 coil packs. un plug and test them one at a
I won't go into how to remove them since it should be fairly obvious Simply remove both bolts
(do one coil pack at a time...) and pull the coil pack out. i had one
where it was very hard to get out... so you may have to pull hard...
Once out, look at the area where you removed the electrical plug. You
should see a "+" on the back end of the electrical plug. There should
also be the letter "B"....
the spot where you see the positive symbol, means that's prong number
one on the electrical connector.
Turn on your ohmmeter and place the positive wire on the 1st prong in
the electrical plug of the coil pack. The negative wire should be
touching the middle prong. Verification of the ohmmeter at this time
should say "0" aka infinite... if it's anything else, the pack should
be changed. Next test: reverse the wires... positive on the middle prong
and negative on the 1st prong.... on a new coil pack, it should give a
value of approximately 1.3-1.7 mega ohms. If any of the readings are
off, replace the coil pack.
Note: Firewall coil packs are extremely easy to find, simply look in the
cracks of the intake header. you'll see 3 similar looking coil packs to
the front ones. The exception with these is that they are longer and
look a slight bit different. removal is the same process as the front
coil packs. Simply pay special attention to not dropping the screws in
the intake area... it'll be hard to get out.
to test: follow the front coil pack testing method. Look for the
Positive symbol, this is your first prong... and go from there.
Good luck (remember rated this help).
