COIL PACK
2000 cherokee sport. Does it have a coil pack or an ignition coil or both. Jeep won't turn over. Put in an ignition coil, didn't work. Took to Pepboys and they said problem was coil pack and needed spark plugs. I thought they were the same thing. Nope..two entirely different parts, so ordered a coil pack - used, on ebay. Did I do the right thing or am I totally confused

When you say turn over do you mean the engine won't rotate when you turn the ignition key to start?
That is a differnet problem from an ignition coil or spark plugs.
It could be a dead battery, or a loose ground connection, or even a dead starter.
If it does in fact turn over but won't start then maybe you do have a coil(s) problem. However I don't think it's that. You have single fire ignition on your jeep meaning you have a coil for each cylinder. Just like a bad plug won't stop the entire engine from running I don't believe a single bad coil will do the same UNLESS there is a safety feature that will not allow the engine to run. Don't know much about that system yet. However it should still turn over (try to start).
Sooooo we need more info.

The engine does rotate, just won't start. Brand new battery. Even put jumper cables on, thinking it was a bad battery. The coil pack I just purchased. Does a 2000 cherokee sport have one of them or is it the long ingintion coil. 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
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.

Unfortunately I traded in my baby with the cash for clunker program today. I was the only owner and had her for 11 years. 230,000 miles so it was the best car I ever had. I wanted another jeep but they don't qualify with that program, but I did get a Dodge...Again, thanks for all the help. She's in jeep heaven by now
