The spark is always blue. If your coil is bad your engine will misfire.

How do you test the ignition coil on your 1994 Geo Metro?
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.
1989 Mazda will not start it is getting fuel and has a good spark from the coil to the distributor cap but has a week spark at the plugs Have replaced ignition coil distributor pickup coil plug wires?
try to get a new ignition rotor
What could cause a 97 z28 to have no spark had coil and ignition control module tested and are good?
is there spark through the wires to the plugs?
Your mx-6 will not start has no spark out of coil but tests good?
TRY IGNITION CONTROL MODUEL. THAT WOULD BE A GOOD GUESS.
94 Honda civic wont stay running fuses good has spark new ignition switch new ignition module new ignition coil?
Check Gas pump and relays
Why is there no spark on a 1994 Mazda Protege if the engine cranks and the ignition coil is in good working condition?
It could be the ICM or the pickup module.
1989 Jeep Cherokee 4L won't start but will try to turn over and it has no spark also has a good ignition coil what could it be?
it could be the coil pick up in your distributor
F250 1989 no spark all new plugs new coil coil wire good what can it be?
I would look first to the rotor, and then maybe at the module check the ignition module
After changing the ignition module on your probe gt still have no spark?
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.
One ignition Coil does not spark on 2002 Mitsubishi lancer?
I had similar problem...Ensure that when you replace the Ignition Coil, you also replace the spark plug (might as well do all 4) and the wires. This will prevent further Coil problems. The Coil could blow the plug or wires and when you replace the coil, the plug /wires will blow out the coil again. Also get a full diagnostic...specifically check to ensure the Head Gasket Cover is still good.
Do you have to grease your new spark plug wires?
You do not have to but it will be very good if you place a die-electric grease on points where ignition wires contact spark plugs and distributor/coil pack.
Why is there no spark on a 1993 Subaru Impreza?
Check that battery has power. Check that coil pack has power and is grounded. Ground out one spark plug and see if there is any spark. If there is no spark, then it is either a fuse or your coil pack is bad. Rule out that the coil pack is good and that your spark plug wires are bad. Test them all individually. Don't get shocked by the 20K volts from the ignition, it really hurts.
