Alright i have my LT4 getting spark and fuel but won't start i have the wires hooked up right i think for the clutch for my 91 camaro so it should fire right up and everythign is gettign fuel checked the enjectors and they are firing and if i spray a bit of starter fluid in there she fires right up and will run as long as i have sparyed it in there fuel pump is brand new so i know it is keeping up with it and i am getting about 45 pounds of pressure what's the deal guys any ideas

 

If you have data logging access, you should check the injector pulse width on cranking.
