when you turn the key all the way forward, it does start the car....so do you mean you turn the key to "RUN" (no it does not pulse the injectors, just primes the FP).
or if you mean turn it all the way forward (to START), but dont push in the clutch, or you have the car in Reverse, so it wont start? for that, if the clutch safety switch/neutral safety switch are open, you might as well not have the key turned to start, so no, no pulse there either.
as i recall, if you are actually starting the car (and it is turning over), the only way to keep it from firing injectors is to floor the pedal (kills the injectors - for clearing flooding, etc).
im not Jrichker, TMoss, etc positive on all of this, but im very confident that this is correct.
also, the injectors spray into the lower intake, not directly into the cylinders (air and fuel need to mix a little first for stability).
let us know what exactly you mean.......
