It is important to recognize the signs of car parts going bad. The symptoms of an ignition coil going bad are bad fuel economy, backfiring, starting problems and engine misfiring.
No electrial spark or fire at the plugs.
A bad ignition coil normally won't allow your engine to start given there is no spark. If it is starting to go bad, it causes misfiring which can be noticed as a stutter, or random shake of the engine. Check the ground of the coil before replacing it.
You can test the ignition coil on a car by using a multimeter. A bad ignition coil can be the cause of a car not starting.
It could either be a bad ignition coil, a bad ignition rotor, a bad ignition cap, a bad ignition control module (if equipped), or a bad coil to cap wire.
Yes, a bad coil will prevent the ignition from firing and the engine will not start.
The engine will either not start, or run poorly if the coil is bad.
There are 5 symptoms of ignition coil failure. They are: backfiring, starting problems, fuel economy is off (less millage per mile), engine misfiring, and vehicle stalling.
Ignition coil is bad, is it right on top of the cap maybe a bad wire in the wirng harness or bad connector.
When an ignition coil goes bad the car will not run right, or not at all. An intermittent coil will cause shudder, or a jerking motion. When the coil has no output then the cylinder that the coil feeds cant burn the fuel and cause power.
Check following symptoms: Weak spark? dirty plugs? old plug wires? bad ignition coil?
You need electronic equipment and know how to to diagnoise the ignition system of the new cars.
