Fuel pressure
What psi should my gauge read and also is it normal for the pressure to drop to 0 psi immediatly after turning the engine off ? Are my injectors bad or leaking ?

i believe it should read between 55 and 60 psi. it is a possibility that you have a leaky injector. if you have stock fuel rail you can pull the rail off the manifold with injectors attached and turn the ignition to prime the the system but dont try and turn it over you'll be able to see any fuel leaking out of the injectors. another thing it could be is the pressure regulator which over time leaks and dosnt hold pressure in the lines but usually thats not a big deal as long as the car start rights up. you could also have a leak some where along the hoses and connectors. if you are in doubt about the injectors you can remove them and send them off to be cleaned and test to make sure they are working properly
