Well i had the same problem first thing you did wrong was put in bosch plugs. thats a no no.. NGK V-Power BCPR6E-11 are the correct plugs for the DI yes Dielectric grease is a must and correct gap .040 theDi sends a signal to the PCM to ajust and with bosh plugs or the rong gap can really mess things up for the DI ifi were you i would do that first then if thats not it. Take and remove the DIafter motor has been OFFfor a minute or two and flip over so the 4 tails are facing upplace the plugs in ang run a wire from each thred to the negitive battery.. Then Crank over to see park if you do not see onespark yourDI is gone try at least 3 time to insure as for the DI its avaible at CarQuestfor $420 big price tag and comes in a GM box although its easy to replace its costly if you end up replaceing the DI contact me and i will give complete directionsfor replaceing and torx specs for everything. Good Luck!
