Normally to repair a cracked manifold its just as expensive to get a new one because manifolds are cast iron, you can get a new one from ebay for 30 bucks apposed to 100$ to have it welded with special matieral here is the firing order

| 2 4 6 8 |

| | 8 ||

Changing spark plug wires on 2001 Jeep Grand cherokee


yah direct ignition coil pack does away for the need a a distributer cap and rotor.much higher energy ignition system where the computer tell when to fire.if that helps.not hard to change.as long as you change them one at a time so you don't screw up the order.

Order of spark plug wires


You didn't specify 2wd or 4wd, but it won't matter as it turns out they are the same. The firing order is 1-5-3-6-2-4. To see a diagram go to http://autorepair.about.com/library/firing_orders/bl-fo-4771.htm

Spark plugs


Firing order for the 4.0L 6-cylinder is as follows:

1-5-3-6-2-4

As for the spark plugs, it looks like the Autolite AL 985 plugs are what you need. If you are going to replace the plugs, might as well also replace the plug wires, the distributor cap and rotor (if you have those, I dont recall which year they went to the distributorless ignition).
