alternator or starter

[fastpace]

Hey what's up yall. Well I got my 240 about a week ago and everything is fine up until now. I let a friend test drive it yesterday. When we got back to the house I was trying to move the car out of the driveway and it would not start. I tried pumping the gas and pushed the clutch as far back as possible. It finally turned on and was okay. But today I was going to go for a little spin around the block and it would not start again. However, after 5 or so minutes the car started up. About 15-20 minutes after this I was going to go put gas in the 240, but would not come on this time. I tried the battery by hooking up some jumper cables. But there was no problem with the battery. My other two reasons why the car is not starting up is either the alternator or the starter. I was wondering if yall had an ideal what the problem is? I don't want to go to the mechanic and I would like to do it myself. I was wondering how much the alternator or the starter are if that is the problem.
