Check for applicable trouble codes. Your security system shouldn't have anything to do with spark. Check for voltage and ground at the ignition module. Pink wire is voltage, black wire is ground. The voltage goes hot when you turn on the key. The pcm controls spark timing during cranking and running. Is there an rpm signal, during cranking? During cranking, do you have good fuel pressure?
