What happens if there is no spark in the ignition coil?

Hence, without this high voltage, there is no spark and, consequently, internal combustion cannot take place within the engine. Simply put, the bottom line is without spark the engine doesn’t run.

How can I tell if my ignition coil is on fire?

Have someone crank the engine and observe the center electrode of the plug — if there’s sufficient voltage reaching the plug, you should see a bright blue spark jump across the gap of the electrode every time that cylinder fires. If you see no spark, the coil is a good thing to suspect next.

How do you remove a coil from an ignition coil?

Use a nut driver or a small wrench to loosen the securing nuts on the coil terminals and remove the leads; the positive side of the coil has a condenser lead attached in addition to a positive lead. Then loosen the bottom clamp screw, pull out the center cable that goes to the distributor and remove the coil.

What should the resistance of an ignition coil be?

Switch the meter’s resistance range to the 20K-ohm setting and attach the negative (black) meter lead to the center terminal of the coil. The reading here should be 11.00 or better, with 13.49 being about normal. If your coil reads under 11.00, then chances are pretty good that this is the reason you’re not getting any spark or a very weak one.
