The light should be on before starting, and for 3 seconds after starting, as a bulb check.

What are symptoms of a bad ignition coil?

A bad ignition coil will cause your engine not to have any spark. Without any spark the engine cannot start or run.


Can the ignition coil cause an engine stall?

Yes, a faulty ignition coil can cause an engine stall. The ignition coil is responsible for generating the high voltage needed to ignite the air-fuel mixture in the engine's cylinders. If it malfunctions, it can lead to misfires, reduced power, or complete engine failure, resulting in stalling. Regular maintenance and timely replacement of a failing ignition coil are crucial to prevent such issues.


How can an ignition module cause an engine to misfire?

An ignition module controls the timing and delivery of electrical signals to the ignition coil, which ignites the air-fuel mixture in the engine's cylinders. If the ignition module malfunctions or fails, it can lead to incorrect timing or inconsistent spark production, causing incomplete combustion. This results in engine misfires, reduced performance, increased emissions, and possible damage to other engine components. Regular diagnostics can help identify issues with the ignition module before they lead to significant problems.


Effect of pre ignition on engine?

, Pre-ignition (sometimes called knocking or pinking) is when the fuel is ignited before the desired point in the cycle of the engine. That is not just before tdc on the cycle, because alost every engine begins ignition momentarily before tdc, and as the engine speeds up - even further before. In essence pre-ignition is an undesired ignition of fuel vapours which has the effect of slowing down the piston as it rises towards top dead centre. Because it ignites before the proper time, it can damage the piston surface, cause wear in the bearings/gudgeon pin/little end, big end bearings or cause extra wear on the piston skirt or cylinder bore. The other place pre-ignition can cause damage is on the valve seats/valve head. Either way the engine has problems. It could be an advance issue (mechanical - distributor or electronic sensor - most modern engines have a pre-ignition sensor), bad fuel blend (too high octane), it could be as a result of a carbon build up in the head/valve area (which can cause a hot spot - a source of ignition for the incoming fuel) If it's a modern car - get the pinking sensor checking at your local garage, if its an old car with a mechanical distributor - check the timing.


Would water flood cause engine sensor failure?

Driving through flood water would cause the ignition to fail and stall the engine.


How can you tell if the ignition switch is bad on a 95 Mercury Villager?

A bad ignition switch, on your 1995, Mercury Voyager, will cause the vehicle not to start. In most cases a bad ignition will cause the engine not to turn over.


Can a bad ignition control module cause a engine to stall?

Yes, a faulty ignition control module can cause an engine to stall. This component is responsible for regulating the ignition timing and firing the spark plugs. If it malfunctions, it can lead to erratic spark delivery or no spark at all, resulting in engine misfires or stalling. Additionally, it may cause starting issues or intermittent loss of power while driving.


Will a bad ignition coil in a 2000 town car cause the car not to start?

Yes, a bad coil will prevent the ignition from firing and the engine will not start.
