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.

How do you test the coil on lesabre 3800 engine?
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.
How do you check a coil for lawn mower?
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.

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.

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.

1993 Toyota Camry no spark motor just died you replaced timing belt tensioner and water pump with new plugs cap rotor and wires you still have no spark coil ohms good what next distributor ohms good?
You could have a bad ignitor. It is located on the drivers side fender well. There is also still a good possibility that your ignition coil is bad, despite the fact that the coil resistance is checking out within specs. I would change the coil first; it's cheaper than the ignitor or the distibutor. If still no start and you have verified that the coil is getting voltage then it is the pickup coil in the distributor. Unfortunately, the pickup coil is not replaceable on its own. You will have to change the whole distributor to get a new pickup coil. Good luck.
