Distribtor does not fire has new coilpac new ignition module new cap new wires and new plugs. need to know what could be causing the problem. a dude dowm the road said he had to buy a whole new distributor. I was trying to swee if anyone knew what could be the problem w/o replacing the whole distributor

I guess you could have the ignition analyzed on an oscilloscope. Maybe a tech could see something then.
I always heard the only gap was the spark plug gap-the rotor has no gap-are you sure you got the correct rotor? And does it touch the top distributor cap coil wire tower?

Let us know. It is a mystery worthy of a solution.

This diagram is for 1998-1995 Chevy 6 cylinder 4.3L engines.
Your got the firing order exactly correct, at 1-6-5-4-3-2, but here's the thing to double-check:
The distributor rotation is clockwise (note badly rendered arrow in picture).





Since you probably got everything right, then you're left with really unusual/rare causes of
failure of the ignition system:
(a) rotor button misaligned/failing to make contact?
(b) rotor button not pressed onto distributor shaft far enough therefore failing to provide correct
proximity to distributor cap contacts when coil fires
(c) coil wire or contact loose/disconnected - press coil wire firmly down into distributor cap.
(d) distributor shaft of other damage caused during installation of rotor.
(e) spark plug wires defective from factory
(f) spark plugs defective from factory
(g) battery low - may need a charge to start
(h) ICM (ignition control module) failure - hook up your HEI (high energy ignition) tester, and
watch the quality of the spark on each cylinder.
(i) fuel problem? If spark is being properly delivered, its gotta be a fuel problem...
(j) distributor cap not screwed down flush to top of distributor? maybe just on one side?

Inspect the inside of the distributor cap - if there are lots of little metal bits all over the inside
of the distributor cap, then you know you have a misalignment of some type in there, and the
rotor and cap are destroying each other. normal operation will throw a quota of spark-ed off
metal bits inside the distributor cap, but since your cap is brand new, your attempts to start
the engine should have rotated the distributor so few times, you should see no metal debris.

Inspect the distributor cap contacts to see if any spark marks are more of less in the middle
of the cap's proper "contact zone". If not, you've diagnosed an internal misalignment, which
you know how to correct.

Coil, ignition fuse, or a bad rotor/cap issue.

Does it have a pick up coil under the distribtor cap if you dont know ask ato zone if your jeep has a pick up coil

get a 20 dollar haynes or chiltons manuel and find the module and coil. always change the ignition module and coil every 4 no more than -5 years to be safe.

take the distributor cap off, and have somebody crank the engine while you watch the rotor, if the rotor isn't turning, then the distributor shaft is broken

Also, if you have not done so, replace distributor cap

Souds like ignition module has failed. Check for 12 volts to mod and replace mod if voltage is good.

Check the resistance of the pick-up coil in the distributor. Reading should be between 800 to 1200 ohms. Disconnect the two wire connection at the distributor control module to measure the resistance.
Let me know.
Regards,

yes it is the ignition coils . po304 is a miss fire on #4 cylinder.wires and plugs should fix the problem unless ignition coil is not firing. there are 2 coils they run 1&4 2 &3 cylinders.
