As to fuel trim it is almost always trying to lean it out. We are thinking maybe a gasket went by by and will pull the upper and lower pleneum and check that next. The regulater seems ok as every one we had go out had fuel in the vacumn line and we don't have that.
You are welcome for the thank you.
Fuel pressure sounds good.

Could be vacumn leak and also check MAF sensor and air intake hoses.
Let us know how it goes.
