I want to send the coil pack back if in fact my jeep doesn't have one of them...Then I will buy the ignition coil and get new spark plugs. Don't remember when I've replaced them...I appreciate all the help though
Hi Kathy, welcome to the Forum from Fantic.
I suppose from what I read that you are not very confident with mechanic skills, but this is not a problem since you have stepped in the right place here.
If i have read correctly the engine cranks but does not fire up right?
There are only two things that cause this problem in a gas engine.
A. No fuel to the engine.
B. No current to the spark plugs.
Since you are already dealing with electrical stuff, I assume that it's option B.
You could easily check if it's A or B with some simple operations, ask me how if you are not sure.
Before you spend other money in wrong and expensive parts and lose the faith in Jeeps you might check a very common failure in a part called
CRANKSHAFT POSITION SENSOR (CPS).
This is a little crappy stupid piece mounted
at the top of the bell housing and slightly to the drivers side with 2 bolts and a cable with connector coming out of it.
Find the connector and unplug replug a few times to see if it's just a cotact problem.
If it's bad you can buy one for
$85 at O'Reilly.
Let me know.
