spark plug is good but when its plug in to coil on spark
I think you remove one of the spark plug wires from the coil and hold it far apart from the coil. Have someone turn the key so the car is turning over. Bring the spark plug wire closer to the coil and if there is spark the coil is good. Note: if you hold to close you will get a very good jolt of spark if the coil is good, that is why you start far away and work your way closer.
start with checking the fuses, coil wire, distributor cap and rotor.
try to get a new ignition rotor
Why start with the module? The coil is is a good place to start. Make sure of course you have voltage at the coil, if not trace it back.
The spark is always blue. If your coil is bad your engine will misfire.
Is there any chance that your fuel has water in it? This happened to an older vehilce of ours and while there was what appeared to be fuel at the injectors, it was too watered down to allow the vehicle to start.
You will still have spark, car will try to start or backfire. If no spark at all the plugs see if you have GOOD spark from coil. If coil is working then you will find the problem in between the coil and the plugs, probably a distributor component issue. The ballast resister is a possible cause also.
If you have access to a spark tester, use it. Otherwise, remove the spark plug, reconnect it to the spark plug wire, and rest the tip or threads on a good engine ground, AWAY from the spark plug hole. Attempt to start it, and watch for spark. If none, replace the spark plug and try again. If still no spark, the magneto coil may be faulty.
it could be the coil pick up in your distributor
To check a coil you just need to take out your spark plug but leave it plugged into the coil and ground the spark plug while trying to turn it over. If it is a good strong spark than your coil is fine. If it doesn't spark than unplug the wire going to it and try it again if it doesn't spark than it is a good chance your coil is bad. if it does spark than it is a wire problem. Also make sure that your spark plug is gaped correctly, usually at about 0.030.
Check spark plug wires, distributor cap, and coil for cracks that let moisture in.
If you know the coil is good then the Igniter is bad. It is right below the coil.
Several things can cause no spark. A bad coil pack, bad crankshaft sensor and camshaft sensor are good places to start.
whats it not doing?? no crank no start or crank no start? thats where you need to start ----cranks good..good spark..good fuel pressure..new battery ..new coil I REPLACED THE COIL, PICK UP, IGNITION MODCULE, NEW PLUGS. WIRES , CAP AND ROTOR. CRANK TRIGERAND FUEL PUMP AND PCM
The coil provides the extra power needed for a good spark, without it, a weak spark may or may not ignite the fuel/air mixture. It's a good idea to replace the coil every 50,000 miles, or every time you replace the distributor cap and rotor.
Disconnect the distributor cap end of the coil wire and attach to an ignition tester. Attach the ignition tester to a good ground, away from any fuel lines. A good spark tester can be made from an old spark plug gapped to 0.200". Crank the engine and observe the tester for spark. If a crisp blue spark is noticed, the ignition coil is working properly. If a pale yellow spark, or no spark, is noticed, the coil is more than likely bad.
Recently had same experience with my dodge and escort. in the escort it was the distributor and the dodge was the brainAnswerCheck your ignition module in your distributor that is a good place to start.
Connect a known good spark plug to a spark plug wire and ground the threads to the engine while cranking. If there's spark to the electrode you know the coil is good and it's sending current through the wire.
If you don't have a known good coil wire to substitute, try hooking a spark plug to the coil wire and grounding it to the engine. Then crank the engine to see if there is spark.
Do you mean you have no spark?? if so, start with looking at the coil packs usually these are the main reason for no spark, if your coil packs are good then work your way backwards with the electrical system. posible ecu fault
If you're not getting any spark at the plugs, check and see if you're getting power to the distributor. If you are, you might just have a blown fuse for the ECM. It should be a 10 amp fuse (red in color) and should be clearly labeled on your fuse box cover. If it's not, just start pulling fuses one at a time and checking them. I had a similar problem with a Prizm and that's all it was.
The spark plugs are located below the 'coil pack' in a hollow tube in the head. You must remove the spark coil retaining screw to access the removal of the soark coil. The reoval with expose the spark plug at the bottom of the hollow tube in the head. The total spark coil is about 6-7" long and when it comes out that is when you will see the spark plug at the bottom of that tube. It sounds difficult to find but once you know it is easy. There is no coil wire(typical spark plug wire) attached to the spark coil. It is fed by a special connector on the side of the spark coil. Look on the side that has the least number of hoses and equipment in the way. Find the top of the spark coil (about 1-3/4-2" in dia) with a wire connected on the side. There is a single small metric bolt holding the spark coil in place. It will not come out until that screw is removed. I hope that this helps. I was lost the first time I looked for it myself. I had the code and wanted to find the spark coil. Good luck
