No spark at plugs


Do you mean you get spark from coil high tension wire to dizzy cap? If so, the only thing left is the cap and rotor and wires and the engine must have a good ground.

Cranking over but wont start


If you smell fuel in the exhaust, then you can assume the fuel pump is working. Spark at the coil is fine but do you have spark to the plugs? It sounds like you have an older car with a cap and rotor. You might have a bad cap or rotor. It might just be flooded, in which case pulling and cleaning the spark plugs would help.

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

No spark, 1988 Toyota Camry 3SFE 4cyl, 5 speed.


there is no crank sensor on this vehicles 2.0L. If you have power to the coil, new coil, cap and rotor try this if not done yet>>>Unplug coil power first....Try pulling off the distributor cap, and make sure the rotor is spinning with the cam...If this fails to spin, inspect the entire distributor assembly. If it passes, Inspect all the power circuit and wiring to the dist assembly, if ok possible ecu. i recommend having a mechanic check it out!! Hopefully this helps...please rate...thanks

Spark from coil but not from plugs


Hello;
Take the distributor cap off, and turn the engine over. Does the rotor turn? Then pull the #1 spark plug and with your finger over the spark plug hole , tap the engine over to top dead center. See where the rotor is pointing. Also check to ensure your points are opening and closing. With an ohm meter make sure you have continuity through the carbon for the coil in the cap. Hope it helps.
Thanks;

Car wont start


do you have spark out of the coil into the cap? if so i would suggest removing the cap and testing for continuity between the center plug (coil input) and the spring loaded button on the inside also check the rotor, if you have no spark from coil at all be sure you have it wired correctly and be sure the coil wire did not get pulled apart in the ends please rate -jeff
