Ok I have spent hours on google trying to find out what my fuel pressure should be at.. And I can't find jack shit... With the key on and engine off it is at 40-42 and when its running it is around 30-35??? So my problem is when it first starts up it has a rough idle for a few seconds then it smooths out.. After I drive it around for say a hour or two then shut it off for a while. And when I go to start it up it just cranks for bout a minute or two untill it wants to start.... I have checked everything but the egr an maf sensors...

 

This seems to possibly be what's going on with my TL as I explained in my most recent post , did you ever find a fix for this ?
