Hard starting '87 Dodge

I have a 1987 Dodge Conversion Caravan. It sits in my drive way most of the time, but I use it a couple times a month to go hunting, fishing, etc. I love driving it, and it runs great, but it is a real pain to start when she's hot. After she has been sitting for 5-10 minutes, I really have to play with it to start it. I usually have to crank it over 3-5 times, and I pump the gas pretty heavily. Is it normal for this to happen? I always have to give her a little gas when I start it, but I am concerned about flooding it.

Sorry...just reread my message, and realized my question is not too clear. I actually have a couple. First, is my van fuel injected? Second, is it bad to pump the gas when I'm starting it? I have tried not doing it, but it just won't start without pumping it. I am just getting frustrated (last weekend, my son and I were coming home from his game and we were stranded for nearly 45 minutes trying to get it started).

What size engine?

V-8
