Did the change of spark plugs cause hard starting?

Question type: Maintenance & Repair
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?

What you describe sounds like a problem with compression on one of the cylinders. Could be possible that one of the sparks is not sitting correctly or the thread is weak, I doubt there would be a problem with the new sparks, but it could be possible too.
make sure all of the NGK's have seals on the plugs- have seen them without thus causing low compression.
could also gap your plugs properly should say the gap in your manual

darnit my high tension wires were toast... i pulled the socket out using long nose pliers... glad i still have the stock plugs and replaced all of them... i think i figured it out... the wires werent able to withstand the current... what more could happen if i put back the stock one? its just temporary though...
the clicking sound i would have associated with a bad battery but since you found the wires that were "toast" that sound you heard was probably the spark plug wires shorting out.
