Still have no spark at plugs after changing rotor,cap,leads.I have spark from coil. 1999 Honda Civic?
1999 honda civic, was driving along and it just died on me. I have changed the fuel filter as I thought it could be that. I had a reply yesterday about checking spark at coil and that it could be the rotor\cap which looked like the issue.Changed these and leads\plugs but still no spark. could the coil be putting out to weak a spark?? I am thinking about returning cap\leads\rotor and trying a coil, what about the ICM, how can I check that? Any ideas?? Thanks!!

If the timing was out I would get a backfire, that's why I think the ICM is cooked or coil is not putting out enough power? Off to store to get replacement distributor, will let you all know how it goes

Double check all the fuses and relays including those for the ECM. The ingitor is known to fail after a lot of mileage, usually these are cheaper on craigslist or a junk yard to verify the problem, you can always get another brand new one if you want to toss the $80+. Can you hear the fuel pump engage? if not check for voltage at the fuel pump relay on all four connections (positive and negative). if you are getting between 6 and 14 volts that is good. check for injector pulse as well; since you know you dont have spark, if you dont have injector pulse, very likely your ECM is bad. if you have any friends with a same model try to swap the ECM. if I catch your update, Ill do my best to respond. Good Luck
Edit: "civicmagnet" has made a very good point; double check all the grounds. There is a rear motor ground which also supplies the ground to the ECM. Verify the ground is there and possibly even add another temporary one to check the ground. Also check: when you turn the ignition to on before starting, check all the indicators lights on the dash come on, if the "check engine" light does not come on, it could indicate the ECM is not sending a signal.
Not many things between the coil and the plugs. Check out the timing roughly by pulling the engine through to TDC and looking at the rotor position, then comparing the rotor position to the towers on the cap. If they seem to agree you will need to get a timing light on the ignition and see if the ignition is firing near TDC.
I have a hunch the timing belt is not right - the timing belt has failed or otherwise is producing a spark at the wrong time. A proper spark from the coil is easy enough to recognize because the Honda ignition is high energy. The spark will have some orange but will be mostly fat and blue, with a healthy snap sound.
I anticipate that you've 2 major themes to regulate now: the unique undertaking, and the 2d undertaking created by potential of the incompetent mechanic. If I were on your shoes, i'd song down the finest Honda mechanic everywhere close to me and performance him look on the undertaking. you basically want someone who's quite, quite acquainted with the ninety 5 Honda Civic to be searching at it now. I somewhat have no doubt that if you're keen to throw a lot of money at it that the automobile would nicely be resurrected. often times, although, that is healthier to diminish your losses and run. no matter if it hurts.
make sure your engine grounds are good. im not sure a bad engine ground would totally kill your spark but its worth double checking. i think your on the right track buying a new distributor.
