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

 

are you positive you're getting fuel? if you are getting spark and fuel you will at least get a sputter. have you removed the optispark or replaced it? make sure you've got it installed correctly. get a code scanner and see if you've got any codes.

 

yes getting fuel and the opti is keyed on it so so only goes on one way

 

Sounds like a vats problem .....gotta love it

I'm glad I had mine taken out of the PCM.

Or the fuel lines are hooked up backwards.
