The coil. ? older post.
the PCM reports even one drop out of 10 , on the CKP or CMP sensors. 99.9% of these changed are good.
why not tell me what you have,? full symptoms and evidence.
got P030x misfiring? are you even using a scan tool,? or working blind.
may be its the coil.?
can can you feel the misfiring.c
can you see the engine shake? all of this is evidence.
do not miss out on that.
does the scan too shop pending misfire codes?
stored codes, or codes while driving, learn to use the scan tool.
do a 60k mile tune up yet?
your engine is not COP coils like the V8
its COIL rail that is a COIL pack with 3 coils inside
that runs 2 sparks each called WASTED park.
so did you try new sparkplugs(dah)first then new coil pack wires HV
next , then a new coil pack last.
start with the cheap spark plug and wires, (called a tuneup)
then pop for coil pack./
misfire can be clogged or leaking injectors too, and that ill skip
with out you using the scan tool fully.

If you have no spark, the most likely problem is a bad crankshaft position sensor. it is mounted on the bellhousing. below intake/exhaust manifold. held in by 1 bolt. A new CrankShaft position sensor should come with a small pice of heavy paper/ thin cardboard to use to set proper air gap between flywheel and sensor.

1993 jeep cherokee. Can't get spark out of coil.


Check the Crankshaft Position sensor. Usually it will reveal itself through the check engine codes. If this is faulty, the coil will not get the signal it needs to fire.
