If you remove the DIC, the cylinder numbers are marked on the head. #1 is towards the pulleys and #4 is near the transmission.

The possible causes are many: Bad DIC, cracked plug boot, no dielectric grease, bad plug, bad injector, bad wire to the DIC or the injector, bad compression, vacuum leak, etc. etc.
