What is an ignition coil and how does it work?

An ignition coil transforms ignition voltage (12 volts) to the very high voltage pulses (20,000 volts or more) that fire the spark plugs. The number of ignition coils varies depending on car model and year of production. Older cars will have one coil covering all engine cylinders while newer cars may have a coil-on-plug type arrangement — that is every cylinder will have its own dedicated ignition coil.

Ignition Coils

When to consider replacing an ignition coil:

  • Hard starting or no start. Ignition coils are subject to heat damage and electrical overload, both of which can cause partial or total failure. If the coil is faulty, you may have difficulty starting your car or it may not start at all.
  • Misfiring, loss of power, poor acceleration. Once the car is running, a bad ignition coil can cause poor operation of the engine. Should you have misfiring or loss of power, faulty ignition coils would be among the list of causes a mechanic would investigate. The Check Engine Light will often come on with a trouble code(s) indicating which cylinders are involved.

How do mechanics replace the ignition coil?

  • The ignition is checked to assure it is in the “off” position.
  • For single coils that supply all cylinders, the coil is disconnected from either a bracket located in the engine compartment or, in some cases, is removed from within the distributor. The replacement coil is secured and all electrical connections reattached. If the distributor was removed for any reason, the timing is adjusted as required.
  • For individual coil-on-plug applications, the coil is detached from the top of the individual spark plug and replaced.
  • Once the coil is securely in place, all electrical connections are reattached, and timing adjusted as needed, the car is road tested to ensure normal operation.

Is it safe to drive with an ignition coil problem?

Yes. A malfunctioning ignition coil will cause loss of power and lower fuel efficiency but that will not present an immediate safety issue. If the coil malfunction is causing misfiring, this will allow unburned fuel to enter and permanently damage the catalytic converter from overheating.

When replacing an ignition coil keep in mind:

  • Ignition coil failure can be caused by faulty spark plugs or wires. The mechanic will inspect and may recommend replacement of those components.
  • In a coil-on-plug ignition system, if only one coil fails, you need only replace the faulty coil. Remaining functioning coils can be left in place.
  • In systems with the coil located in the distributor, it may be more cost-effective to replace the entire distributor rather than remove and replace just the coil.

98 1995 - Oil Pressure Light is on - Houston, TX
They just sent an email saying the mechanic is on his way. It is only 8:12 am! He is off to a good start. He is supposed to arrive between 9:00-9:30 am. He arrived well before that time! It was not 9:00 am yet! He did a diagnostic and he checked all the work I did. He said I did great work with everything I did. He said the car is very good shape. He said this car is indeed a runner! He checked everything. He checked all the fuses and relays too. He did a complete diagnostic too. He checked fuel pressure, oil pressure, and more. He found out what it was. It had nothing to do with oil pressure or anything. The fuel pump is going out. When he came the car started right up. He said they never go totally out. He said that is why it started when it did. He connected tools I do not have to the Ninety Eight. It is not getting any fuel pressure, and this is why it shut off all the times it did. He fixed one of the spark plug wires too. It was burnt. He jacked the Ninety Eight up and got underneath and checked the wires, the oil pressure sensor/switch and oil level sender for everything and the connections and made sure they have power and were installed correctly. He said the engine uses oil pressure along with the fuel pressure to start. The fuel pressure is non existent and that is why it would not start. After all of that, he looked at the Oldsmobile Toronado, my other car . He got the air conditioner to work again. He said the compressor bolt was loose and he tightened it up. He used this huge screw driver device and bent it back in place. He said the shims were loose and he bent them back. It cools just fine now. We turned it on and off several times testing it. He checked the pressure and it was filled with refrigerant. He checked the relays and the fan too. It was all fine. He said it is clear you take care of both of your cars. He said one thing I will not do is guess and I like to know what is indeed wrong. He said your cars are in good shape. He said you do not need valve cover gaskets. There is no leak. I booked him to return to install the fuel pump I need. I look forward to seeing him again soon in a few weeks. Today only cost me 70.00. That's it.

98 1995 - Oil Pressure Light is on - Houston, TX
The mobile mechanic came. I must say I am impressed! He found my house. He and I started talking. He said he owned two Ninety Eights previously. He was there to look at my Oldsmobile Ninety Eight. He had two Oldsmobile Ninety Eight Touring Sedans. The ones he owned were from the 1987-1990 era. He was describing the floor shifters and they had and how much he liked Ninety Eights, Touring Sedans, and the Oldsmobile Eighty Eight LSS too. He talked about how a family member owned one and how he was fixing his. He talked in detail about the Touring Sedan and the things he loved. He asked me how long had I owned my Ninety Eight. I told him 2003. He told me how he become a mechanic and went to school for it and more. He got into the Ninety Eight and it would not start. He got out and disconnected the battery and rubbed the negative and positive battery terminals together. He reconnected them and the Ninety Eight started! The instrumentation then told him exactly what it was. There is a sensor at the bottom of the oil pan. He said by doing what he did with the terminals, it cleared the computer and reset it. We went underneath the car and he showed me the sensor. He said which one did you replace? I told him. He said you were on the right path. You know what you are doing. You need to replace this sensor and not the one you did. You can get the sensor and replace it because it is clear you know what you are doing and on the right path. He said you also need to replace your valve cover gaskets. They are leaking. I told him I will request him to come back and do that. I am not doing that even thought I can.
