I have a 99 Civic Si and it just stopped firing altogether. One second it was running, the next it just shut off. The engine cranks, but there is not spark.

I replaced the spark plugs, distributor cap and rotor. The engine is still not firing at all.

Could anyone give me some suggestions on what to do from here? Preferably someone who has had this problem in the past.

Thanks in advance.

Check the coil/igniter.

 

What would be the best way to check to see if the coil is working? I know where it is, just don't know how to check if it works.

 

Someone else would have to answer that one, but I believe u have to check for the proper voltage, if any.

 

Ok. Thanks for the suggestion. Anyone know how I could check to see if the coil is working or any other suggestions to the problem? Thanks

 

Ok to put this simply, you can take the time to check voltages etc and confuse the **** out of yourself, or just find a buddy or a junkyard/salvage with another coil and make it easy and swap them. Cheap and an easy indicator.

However, the coil doesn't seem to be your culprit. My suggestion would be to check your Crankshaft and Camshaft sensors. Not 100% sure but they should be AC sensors, so just put a Voltmeter set to AC Volts onto the two pins of the sensor, have someone crank the engine over and watch for voltage. If it makes AC voltage, 99.9% chance its good, if it doesn't make any voltage, replace it and enjoy driving.

 

Check grounds. I've had situations where my car developed rust overnight after a rainy night/day and wouldnt start. sparks on some grounds due to corrosion. sanded them down, retightened them and bam. on other occasions it was my distributor/ignitor. other times, the spark plug wires were fried.

it could be any number of things honestly. just go one by one, checking all aspects of it, before you go really tearing into anything.

grab a multimeter and poke around.

 

Thanks for all of the suggestions! I ordered an ignition coil because I found one cheap ($28) and it started up! If something like this happens again, I'll keep all of your suggestions in mind. Thank you.

 

I decided to do the coil first because the spring that attaches to the cap looked a little messed up and thought it should be replaced anyway
