there is a small nipple on the fuel rail...looks like a valve stem for your tires. open it up and push the pin in. If fuel sprays out then you have good fuel pressure before the injectors. If it just drips out, then your fuel pressure is not what it needs to be.

Well, you have good fuel pressure. I will do some research and figure out where to go from here....so it only dies in D or R? Have you flushed the trans and changed the filter?
