Hey, so I have another rotary that turned off one day and will not start back up. I pulled all my plugs and one of them had the black goop on it, so I replaced it. I cleaned the rest off with starter fluid, deflooded the engine, put new coils on, upgraded to an optima redtop, put everything back together and when I turn it over, it runs for about 1-2 seconds and dies. If I try to start it after it dies, it hits but will not completely fire up. So, I take my spark plugs back out and 3 of them have fuel on them, and the 1 I replaced has just oil, or I think it's oil. Is this another symptom of bad apex seal? Do I have a fuel injector out? Is my fuel pump failing? I've tried pop starting it but at 18mph it turns over a couple times but doesn't seem to get enough fuel to keep it running.

Spark plug location is the top left, trailing, not sure if that helps.

 

Sounds like the plugs are not in the correct order. Also do the 20 brake stomp. Make sure you CAS is plugged in and clean.

 

The engine should run if you have one good rotor. Have you replaced the coils?

 

I've done the 20 brake stomp, plugs are in order. I'll check the CAS when I get back home, I forgot to mention it is an '03 with 108k and original cat.

All 4 coils were replaced at once

 

So I cleaned the CAS and I guess that was the problem. I cleaned all the spark plugs with starter fluid, put them back in, this time I tried to make sure the engine wouldn't die and she was smoking like a freight train. The sensor had black junk all over the tip so I cleaned it off and now she runs. Thanks for the help guys.
