I have a 2002 i35 that has a P0021 code, I pulled the plug on the vvt solenoid and was testing the plug with a multimeter. The plastic connector Broke so the connection leads are now bare. With the key on, the connection leads touch and created a spark. Now the car won’t start. Did I fry my ecm? If so can I replace it myself?

 

Also the car is not getting spark
