Vacuum Problem?? Help Please

I have a 2002 wrangler sport and i was wondering if anyone had the same problem that I do. Most of the time you have to keep the ignition turned for a few extra seconds for the jeep to crank. The jeep always starts but it is delayed. It will start right up the first start of the day but each start after that though out the day it is delayed. I know that i have a vacuum problem because i have the classic defroster and cruise control problem. I know that is a vacuum problem. Hoping to work on the problem this weekend but wanted to check out if anybody knew a definite fix first.
Thanks

Look for the elbow fitting near your intake. that will take care of your defrost and cruise. Your cranking problem is probably fuel pressure regulator related.

As Zeep said, a likely spot for the vacuum leak is the take-off port on your manifold. Mine was harder to find, however. I took a hand-held vacuum pump and tested each line individually and eventually found the culprit. It was the rubber elbow on the vacuum canister in the right front wheelwell (I don't remember the exact location). It's not round like the old school canisters, but square.
Rubber hose replaced; no more HVAC problems.
