Ok guys any help is greatly appreciated. I just bought a 2000 grand caravan sport. It has the 3.3L motor in it. After it sits for a long period of time, such as overnight, It cranks for several seconds before turning over and starting. It does start and stay running though. When it starts I can smell gas inside the van. I have been looking for days for an answer of where to start. Everything i have read points to the fuel pressure regulator. Question is where is the FPR located on this car? I looked along the front of the motor on the fuel rail and in the close proximity and cant seem to find the regulator. Thanks again for any help you can give.

THanks for that helpful diagram and the help locating it. I will have to wait until i get lower on gas to do that though. Does it sound like I am on the right track in my diagnosis or is there something else i should try?

 

Maybe a leaking fuel injector? Look for a wet plug or heavy gas smell from a particular cylinder. Any evidense of a leak anywhere near the tank or fuel lines?
