i bang on the starter for about 2 minutes then i wait for the fuel pump then i start

 

I used to have a car like that.

I also had one that I had to bang the battery. And another one that I had to bang the starter solenoid which was located by the battery on that particular car. I believe is was an old cherokee.

 

any idea on how much one of these should cost...maybe a part number also?

also... are they hard to replace?

 

mine cost $50 through advance auto parts. They're real easy to replace, no more than 5 min.

Here's the part for yours:
IDLE AIR CONTROL VALVE

Let me know if this is what you're looking for.
