Engine Diagnostic Test 850

posted by  someone claiming to be Shaker on  Mon Jun 18 20:18 CST 2012 [RELATED]

Klaus,

Thanks for the response. I have pulled the entire rail and put small mason jars underneath. When I turn the key to the II position they give an initial 5 second prime. I also crank it and the engine will run for a minute or so from the fuel already in the cylinders. Afterwards, they all have relatively the same amount of fuel in the jars. None seem to be significantly more than the other. Also, I have put a jar under the return fuel line that runs from the fuel pressure regulator and nothing comes out of that. Shouldn't the fuel pressure regulator be sending that excess fuel back to the tank? I don't have fuel coming out of the vacuum line so I know the diaphragm hasn't ruptured, but is there a way to test the other output? How hot should the fuel injectors get? After the car ran for about 2 minutes I waited about another 30 to pull the fuel rail and the injectors were so hot I couldn't hold them with my bare hands. Maybe a short somewhere? Last Idea:::::: Could I pull 1 injector at a time and start the car to see if I still get flooding? Would this do any damage to a cylinder? Again, thanks for all your help.

Shaker
