[Diy_efi] could i have multiple bad injectors?

as a background, i have just installed staged injection on my 6 cylinder, as 
it was being tried out, the smell of fuel was prevelant without the car 
running. after searching for leaks, i could see fuel leaking in between the 
upper and lower intake manifolds, because it was leaking past the injector 
and into the manifold, then puddling and seeping past the gasket

... now, how could i have more than 1 injector do this? the odds are pretty 
astronomical i would think? the secondaries are bosch style 440cc injectors 
out of a talon (1 and a half sets) and the car ran great before removing the 
very injectors i am trying to use, and upgrading to larger ones.

so to summarize, i have 2 or 3 failing eclipse/talon/laser injectors, base 
pressure is only at 37 pounds, and there is no electrical signal going to 
the injectors to open them. i can't see the injectors having a normally open 
coil, or everytime the car ignition was on, and the fuel system was primed, 
it would flood before the ecu started to oscillate the injectors and 
signalling them to close

sorry for the long post, i just can't figure out what is going on here, any 
and all info or theories would be appreciated. thanks
