Misfiring


The coil is inside the distributor.
You could pull one plug wire at a time and use a spark plug or tester to check for spark.
Usually a visual exam will find fault with the cap or wires.

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.

I put a new long block in my 1997 Chev truck 1500 4.3L Vortec. I am not getting any spark from my coil to my distributor. What tells my coil to fire? And where do I check it?


If you have a distributor then it is the one that tells the coil when to fire then it distributesb to the correct plug. What you do not have is ignition power, be it manual or electronic ignition. Check for that. A picture of your ignition system or deeper description would help.

2000 chevy siverado radom missfire


Hello: Have you recently had any work done to it ? It may need a tune up.That includes spark plugs, spark plug wires, and a distributor cap, and (rotor if applicable).You may have a bad or cracked spark plug wire causing the spark to jump once in awhile.

Need firing order spark plugs 98 chev express 1500


I am going by the '99-'06 Full size truck Chilton's Manual. The firing order should be the same. It is 1-6-5-4-3-2 on the v-6 engine. 1,3,5 are on the driver's side from grill to firewall and 2,4,6, are on the passenger's side from grill to firewall(this is in the heads). From the boot coming off the main coil(the only one not going to a spark plug) clockwise the firing order on the distributor is 5-1-3-2-4-6. Also make sure the plugs are gapped at .060 in. Hope this helps.

Distributor cap and rotor location on chevy silverado


Most chevy 5.3 do not use a cap and rotor. Most have single coil per spark plug and wire. Trace spark plug wires to coil usually above the valve cover.
