My car has some hard starting issues as well. It is periodically that the car will not start until the second or third try. I find that if i turn the key and let it sit for 5-10 seconds until the radio kicks on(stock mach amps power up) that the car starts pretty well every time. If i just turn the car over with no delay it may not start well. I really wish I knew why the car started hard sometimes.

Have you checked the basics like.........
-clean all connections at the battery
-clean the body ground
-clean connections at the starter
-had the battery checked (they can sometimes have lots of amps to roll the starter over while the voltage has dropped low enough that the ECM will not properly function)
-fuel filter (has it been awhile??)
-plugs (old or maybe have the wrong ones in there?)
Many times it's the simple things that cause that kind of issue.

After doing tons of research about my problem, a gummed up IAC is a very common cause of a hard start. Take it off, it's just two 8mm bolts and clean it inside with some carb/TB cleaner. While you're at it, disconnect the battery and reconnect it once the IAC is cleaned and back installed so that it resets the KAM memory. :tup

Another tip to help those with rough idle would be to check vaccum lines they can cause havoc.
