I've just changed my inlet manifold for the same one just painted red as the original paint flaked off. I started it up and it ticks over ok but when I press the pedal it stutters then cuts out. I had removed an injector when I started the job and put it back. Could I have blocked it on putting it back in? Does anyone know the correct seating position for the rubber seals?

 

i would of said its seated properly when its not leeking fuel...
