I will try to shorten this as much as possible.After my car sat for a few hours, got in it and fired it up and it would sputter and die did that a couple times and then began to run fine, I held it at about 3k rpm for a couple seconds and let off. It began to jump from about 1300 rmp to 2100 rpm on its own (map sensor??) that what I initially thought. All the while the car has had a tap tap tap under the valve cover not bad enough to make me not buy it of coarse or bad at all really but it was there.


I removed the plug wire cover from the valve cover and the plug wire on the #1 cylindar was jumping around a little and also was not pressed and seated as good as the other 3 so I press down on the top of the plug wire on top of the plug and the taping stops so...("death tap") right?? AKA loose plug?? well I drive it home and pull the plug....
Plug was tight but the ceramic piece of the plug had seperated itself from the metal at the base where the socket grabs the plug at. I get in my truck and go fetch a good new plug and come home. I jump in to start her up (on 3 cylindars) no plug no wire on #1 and it spits and sputters for a second and dies on its own.... I put in the new plug and put the wire back on and now it wont run at all just spin over and over and never crank up???? HELP!!!! Fried coil???Ignitor??Both?? I need some advice!! Remember this is a 2000 civic si EM1 b16a2....Thanks in advance for any help!

Do you have a CEL?

When you say you started it up with only 3 spark plug wires it sputtered. You need to have all 4 hooked up. There's a firing order that it goes by.

1) Check your firing order, make sure it's correct.
2) Ensure your timing is correct (dizzy and cam).
3) Use a compression gauge and check compression across all four cylinders. It should read between 140-180 across all cylinders. It should also be even across all cylinders. If one is lower than the other, you'll know what cylinder has problems.
4) Check for charring/residue on the end of any spark plugs. That will indicate whether there's an issue with that particular cylinder, or spark plug.

It sounds kinda like compression to me, but it's hard to tell without actually being there. If your car is throwing any CEL's, it would be good to get an OBDII reader and find out what they are. Also, do you smell fuel strong when trying to crank?

No fuel smell or CEL. I know it runs better with all 4 hooked up but runing it on 3 the car should still run just not well. Since then it has not ran at all and I do not know if it just happened that way or if it had to do with me cranking it on just the 3. I wouldnt think that cranking it with just the 3 would really mess anything up though people do that all the time to blow out the cylindar after drilling and taping spark plug holes and other various reasons.
