Hi guys. I really need your help. I have a 97 civic with an ls engine. Im having a problem that when i run the car for a while it will shut off and wont start for a while(it will start after waiting for 30 minutes and it will do it over again). Ive been doing research and have gotten alot of possibilities. Ive read it can be the ignition coil, i changed it and its still doing it, they said it could be the coolant sensor i changed it and nothing, they said it could be the fuel pump but i hear it turning on and also it will literally just die completely. RPM's just go to zero like if it was a alarm cutoff. So its not the Fuel pump. When it happened to me yesterday i checked and it had no spark. I would appreciatte some help and some input, it is extremelly frustrating.

It works perfectly before it turns off, it has no engine light or any light whatsoever.

thanks in advance

 

I would try changing the ignitor module inside the distributor (if the OBD2 dizzy has one.. I'm not sure)

 

yes sorry. that's what i called the ignition coil and nothing. But thanks. Anybody with that problem before and solved it?

 

Did you also replace this:

 

i did replace what is on the second picture. Ill check the module tomorrow. I thought it was the same thing i checked but looked diff. Thanks netfreak. This is really frustrating and i really appreciate your help

 

Check your wiring.
