Take it for what its worth but I was told that the two plugs on the transmission if loose can cause this problem amongst others. There is a plug for the neutral saftety switch and if it is not securly in its slot then this MIGHT be the cause of your problem . You can find both of these plugs one on either side of the transmission coming down and plug in just above your oil pan

318 ci. Why does it lose fire to new coil?


Check for loose wires around the coil post also check for broken wire inside the dist/pickup coil in the distributor and if maybe a relay is intermittent in the ignition system. Hope this helps. .

Do you have battery power at the coil when the key switch is on and when the engine is cranking ?
The rotor on the distributor is turning, right ?

No spark at coil or distributor


I would buy a book with the procedure to troubleshoot the ignition system. The problem could be the pickup coil in the bottom of the distributor among other things. The module uses the pickup coil to know when to fire the plugs. The computer only controls when the cylinders fire.

I have a 1993 chev pick-up v6 4.3, i just installed new spark plugs,new plug wires, distributor cap and rotor button.All plug wires are back in the right position,and i used the firing order 1-6-5-4-3-2...


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.

Are you getting power to the red and green wire on the module with the key on and power to the red and blue wire on the module when cranking? If yes, I would say you pick-up coil is bad.

Your problem sounds like the distributor, points and pig tail wire.
I suggest you try changing the distributor / servicing the points and pigtail wire.

The reason why p 1 inst firing is cause it isn't getting any power from the distributor. because of this it has the ripple effect your experiencing.

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.
