Make sure it is not antifreeze coming out. Thay much gas in a engine to come out exhaust would flood and not run.

Maybe leaking injectors how does it run? dual exhaust no H pipe? Pull hose offf regulator gas present? 8 digit in VIN if W fuel pressure 55-61 psi if Z then 9-13 psi

It idles ok but you can tell its not running on all cylinders. It has a Y pipe that goes into 1 exhaust pipe. The fuel pressure regulator is inside the intake. should I take the top half of the intake off and check it that way?

I checked the fuel pressure & it was reading 35psi with just the key turned on not running. Does that mean a bad fuel pressure regulator?

I found out what the problem was ! The fuel return line inside the intake had a hole in it. i finally took off the top of the intake & it was full of gas on the right side. After further investigation I found the hole in the line. Replaced the part & it solved the problem. Thank you so much for helping me,your the best !
