I need a wiring diagram for the ignition control module and distributor cap on a 3.0 V6 motor

check coil wire--distributor /dist cap

Ignition module is bolted on bracket with ignition coil. Not likely to cause issues in wet/damp weather. Suspect faulty distributor cap or ignition wires as the source of the problem. You can run the vehicle and use a spray bottle of water and spray around the dist. cap to see if engine falters or stalls. If so, that will be your problem. If ok, spray around the ignition wires to see if any problems arise

Hi mate start at the easiest point which will be to check your EARTH to make sure everything is earthed.

coils

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.

OKAY STANDING IN FRONT OF ENGINE ON LEFT SIDE CYLINDERS FACING YOU IS 1 3 5 ON RIGHT SIDE DRIVER SIDE CYLINDERS FACING YOU IS 2 4 6 LOOKING AT DISTRIBUTOR CAP NUMBER 1 SPARK PLUG ON CAP IN THE 9 OCLOCK POSITION YOUR NUMBER 5 SPARK PLUG ON DISTRIBUTOR CAP IN 6 OCLOCK POSITION .STARTING AT NUMBER 1 SPARK PLUG ON CAP COUNTING CLOCKWISE COUNTING 1 2 3 4 5 6 THATS YOUR SPARK PLUGS WIRES ON CAP TO ENGINE PLUGS. 6 PLUG WIRE ON CAP IS AT 7 OCLOCK POSITION.

The distributor cap and/or the ignition rotor most likely have a crack somewhere and the distributor cap should be replaced along with the ignition rotor. The ignition module could have been damaged as well as the ignition pick-up coil/stator and if replacing the distributor cap and ignition rotor does not solve the problem then the ignition module or the pick-up coil/stator assembly inside of the distributor is also most likely damaged and the distributor will need to be replaced. There is a certain procedure for removing and replacing the distributor, and the ignition timing is not adjustable and it is not set using a timing light or with the engine running, and if you do have to replace the distributor Let me know if you require the procedure to properly remove and replace the distributor or if you require any further assistance.

from spark plug there a wire (high tension wire)connected to distributor cap, and from the middle of the cap there a wire connected to the ignition coil

I believe those motors have a distributorless ignition system. Each cylinder has a coil mounted on top of the valve cover.

1) #1-4 pass side front to rear #5-8 drivers side front to rear
2) 1-3-7-2-6-5-4-8
3)#1 is usually marked on cap wires go ccw
4) TDC #1 cyl you must remove the shorting plug before timing
it is located by the dist plug or the ignition module small gray plug
