    Just had a tune-up...distributor checked OK...don't know about the capacitor...why would capacitor affect only 3 cylinders? Thanks.

Did you change the rotor inside the cap and there is a capacitor in there also and you might want to check the gap on your plugs

    the rotor may be worn just right and your not getting getting spark across the gap also your cap. may not be giving off enough juice to cross that gap your losing the spark some where since you are getting it at three of them it could be a combonation of any of these things or some i have not thought of have you changed the plugs can you check for continuity from the distributor cap to the plugs and do you have a coil pack that regulates the spark

How to Replace a Distributor Cap in Toyota?


Its a plastic cap and and on its top the sparks wires get connected.A small plastic rotor spins inside the distributor cap, firing each spark plug as it rotates. If the distributor gets faulty there the engine may not perform well. in most cases it has been noticed that only replacing the cap does not helps but with cap the rotors also need to be replaced. The procedure is as follows:--- 1) First of all disconnect the negative battery terminal. 2) Then remove the spark-plug wires . Note:-- Before removing the spark plug wires please note down how and where the wires are connected,then only remove the connections. 3) Then on the distributor there will be a cap.remove that cap.the cap is connected by two pins.you will have to press the pins from each side to loosen the distributor cap.Then lift the distributor cap from the top. 4)Then remove the rotor From distributor The rotor is fitted with two screws.Remove the screws and loosen the rotor. 5) Then lift the rotor out from its shaft. 6) To install new rotor and cap.reverse the procedure. This will help.Thanks.

Spark plug wiring from distributor cap to spark plugs on a 95 honda civic dx 1.5 liter 16 valve sohc


If you look at the distributor cap from the wires side carefully, you would find either a line mark on one of the outer side of four holes (where the spark plug wires are inserted) or the numbers printed on the top of distributor cap (1,3,4,2). Fix one end of the longest high tension plug wire into number 1 hole or the one marked with a line mark on the distributor cap and the other end on spark plug number 1 (the number 1 plug is toward the pulleys and the belts side, then No 2, No 3 and No 4). While standing in front of right wheel you will see the distributor cap in front of you. The rotor moves clock wise. After you fix the 1st cord, next comes number 3 plug wire. Insert one end of the cord into the next to 1 on the right hand side and press the other side of the cord on spark plug number 3. Next to 3 is the cord number 4 and the last one is number 2.

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.

1987 GMC Jimmy Distributor cap and Rotor replacement


A diagram may not be needed as its a reasonably easy fix to do on your own.the distributor ca p will only fit on properly one way because at the base of the cap locaters can only fit the distributor if they line up.When doing the spark plug leads do them one at a time and if nessecary write or mark leads as 1,2 etc .The rotor can only fit on one way but put a mark on the distributor to show where the rotor was pointing when you took it off and if it still points there when the new one is fitted.When changing distributor cap and leads they have to go to the correct place.Pays to mark the outside of distributor cap where the locating bits are On the new and old one.Fit the new cap and rotor then take a spark plug lead and fit to new cap 1 at a time.You can tell by lining up the marks on the outside of the distributor cap when you hold them one on top of the other.Good luck
