Non starting Sebring
 

I have a 1997 Sebring Convertible, 2.5, saturday car wouldn't start, no spark, pulled the distributor and had it tested, they said it was working intermittently, put in a rebuilt distributor, still no spark, there's also failure to connect to my OBDII reader, does this sound like the ECM? If so, anyone know a source for a reasonable used ECM in the L.A. area?

Thanks
