Sometimes when I turn my key the engine doesn't turn over right away. Will this problem be remedied by simply changing out the spark plugs or could it be something else. Thanks in advance for the help.

Yeah if your plugs are really wasted it would make it hard to start, but its
probably something else. What kind of plugs are you running, and how many
miles on them.

Ive been dealing with this problem for some time. I ended up replacing the fuel pump and it fixed it for about 2 weeks but now its doing it again but not as much. I have a year warranty on the pump so may take it back and try it again. Im going to do plugs as well (66,000 miles). I did the IAC valve but that didnt help.

does it sound anything like mine? clip starts @ 8 seconds http://media.putfile.com/Flows-and-OR-Pipe--Startup-And-Idle-

now compare that to my warm start up clip.. fires up right away: clip starts @ 6 seconds http://media.putfile.com/startupppppp

on cold start i have to hold the key longer to get it to start. WHen its warm i can just flick the key. If i try to flick the key while its cold iget a nasty sound from the starter.

we changed the fuel filter and it didnt fix it.

I cant listen at work but mine does it only when hot and is fine when cold except for one or two times. I did the fuel filter with the pump.

I'm running the stock plugs still (I havn't replaced them). They have about 60,000 miles on them.

Both of my Mustangs do it too. Seems to happen right after the engine gets warm.
Changed the fuel filter in one of em and so far it starts right up.
