Whats make a Ignition coil not get fire

It could be your crankshaft position sensor, which measures the rotation speed (RPMs) and the precise position of the engine crankshaft in relation to top dead center. If you had an intermittent stalling condition before this no start, this is most likely your culprit. It is located behind your engines main pulley. This may also produce a P0335 code if you have a check engine light on.. Hope this helps you.
