SOURCE: No spark?

Hi, common thing with the mazda was the coil or the ignition amplifier going faulty, both of which are located within the distributor, the coil ususally gives the symptoms you describe, a weak spark. The coil is the most common failure aswell for your vehicle i would recommend a new one, also make sure distributor is spinning as it could just be a case of a broken timing belt.

Good luck Davelee

Do you have voltage to the positive post of the ignition coil with the ignition key turned to run? You do not mention that you have done any testing for system fault codes either, this is a very important test.

Why is there no spark from spark plug 1995 k1500 silveraldo


1995 silverado has a distributor, remove the the distributor cap, make sure the distributor spins with the engine. also make sure the ignition rotor is not burned out or have a hole were it makes contact with the cap. also make sure the cap has a good carbon inside to make contact with the rotor, at this time get a screw driver, put it on the end of the wire from the coil to the cap, don't touch the metal part of the screwdriver, it will shock you if good, so put it at 5/16 from any metal on the engine, bracket, alternator , thermostat housing no matter, some one turns the engine over, check to see if the coil produces a spark, if the rotor turns, if ok it should have spark on all the wires, if it has no spark, remove the wire from the ignition coil and check if you have spak at the coil, if you have no spark, try getting a wire lead, connect it from the battery ground on one end, a screw driver on the coil to check for spark, and the other end of the wire with the key on, touch the - negative plug on the coil, that should produce a spark, if not spark yet, make sure you do have power at the coil with key on, if you do and it doesn't produce spark, replace coil. if it does spark but it is weak or yellow in color, replace coil. if coil is fine, replace distributor module,

Ignition mystery! 1994 GMC Suburban 2500 5.7 mtr. No spark to spark plugs. Have spark from coil to distributor. Have changed coil wire, cap, rotor, ignition module, and coil. have 12.5 volts going to...


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.

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.

On a 1992 chevy 1500- 350 engine, I can not get this thing to get a spark- i have replaced the plugs and wire, distributor cap and rotor, but you still don't even get a spark, it's getting fuel... Please...


Hi, Hope I can help you.
I do not know how you have checked for spark, but lets start from the beginning.
Lets start with an ignition systems check.
1. I want you to remove the high voltage coil wire. ( That's the wire in the center of the distributor cap.) Using a good pair of insulated pliers. I want you to hold it about 1/4 inch from a good engine ground. Now you will need a bit of help from a partner. Get them to turn the key and crank the engine. You should see a bright blue and well defined spark. Ok, If you have spark I want you to slowly move the coil wire away from the engine ground. As you do this I want you to pay attention to the coil tower. (The coil tower is where the other end of the coil wire is attached.) What your looking for is arcing and sparking at the coil tower. If this happens then you need to replace the coil with a new one. If this does not happen then your coil is working fine, and we will have to move on.
Note if you do not get spark from the coil wire replace the coil.

2. Ok if you have spark now we have find out if the spark is making it to the spark plugs. How are we going to do this? By checking the rotor, distributor cap, spark plug wires and spark plugs.First lets remove the distributor cap. This will allow use to inspected the rotor and the distributor cap. What your looking for is, cracks, carbon tracks and wear at the tip of the rotor. On the distributor ,look inside the cap for cracks, carbon tracks and wear on the terminals. If you find any of this replace the distributor cap and rotor. ( Note if you have any doubt of the condition of the rotor or the cap replace them.) Next lets check your spark plug wires. Lets pull off one of the spark plug wires from the spark plug side. Now inspect the wire connection for a white crusty powder. If you find crust replace your wires. Now you should check all of them the same way, but if even one has corrosion replace them all. You are going to have to inspect the wire its self . Going down the whole length of the wire. Holes cracks burn Marks and other damage. Once again if you find any damage replace them all.
I hope this will help you and good luck to all the read this FixYa
leave feedback thank you

sounds like your rotor is bad, it does happen, and that would explain no spark to ignition wires to the plugs-look inside the distributor cap too, and replace it if you see moisture, hairline cracks, or the terminals are badly oxidized.

Where is the rotore /cap located in a 1999 silverado 4.8


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

No spark


Possibly the crank sensor.
