but it wont start unless i spray a little starter fluid into the intake. it didnt do that while it was in my other rig. the other thing is that if i snap the throttle open it dies. its a 93 4.3 vortec w/ 700r4. im thinking its a fuel problem (i have to dig my pressure guage out). i had a spare cpi unit that i swapped in but that didnt help. anybody have some ideas as to what i should look for?
