Did the change of spark plugs cause hard starting? i recently changed my Denso performance plugs and put in new NGK V-Series plugs... i tried starting the engine but it's not starting after a few clicks... it starts immediately when the engine is still warm but hard in the morning...my old plugs do not have problems at all, they're just old and worn out... idle is also lower than usual but a slight acceleration difference is felt...its the starting that bothers me...could the change of plugs cause this? 
If you think a good mechanic is expensive, try hiring a bad one

Possible, if you put the wrong NGK plugs in.
Probably should be a ZFR5F-11 OR ZFR6F-11.
Screw the old plugs back in for testing how it starts, maybe you have something else going on there.

if it doesnt happen with the old plugs i think you awnserd your own question...but if it does, sounds like possible fuel issue, not staying presureized?
