you need to disconnect the hoses above the fuel rails, remove the air instake hose, remove those filters on the hoses, remove the fuel lines off the fuel rails, pull the fuel rails up not sideways you may brake the injectors! the injectors do not screw on they just pop in and out of the fuel rail and engine block...pretty simple id be glad to do it for anyone free if your around elizabethtown ky, i have a ls400 1991 and i know these cars pretty well!

Cleaning the fuel injectors is a good start.
67 chevelle's never had fuel injectors, they had a carburetor.
Fuel filter, fuel pump, or pressure bypass/relief valve is not providing the correct, enough fuel pressure at the injectors.
When all fuel injectors are stuck open, this generally means that the injectors are not getting the right voltage. You will need to not only check the voltage, but make sure the injectors are receiving the right signal.
take fuel rail off unplug injectors from wiring harness pull out injectors make sure you get all the rubber o rings out of the intake manifold and fuel rail reverse for install
NO, The injectors are different on the 454
behind right headlight
fuel pump or fliter
