lt1 4 cylinder?
just finished my swap and noticed im running on only 4 cylinders. i have spark on all 8. 12 volts on each injector. i have continuity from the pulse wire on each injector to the pin on the ecu. so there i know a wire isnt spliced. shorted. or just plain not connected. now the car runs off the front 4 cylinders only. that would be 1 2 3 4. 5 6 7 8 are not. it kind of looks funny. 4 header tubes have the paint burned off and 4 dont . any sugestions? i checked on the red plug to see if the ground was working properly. and it is.

Lets see. Your getting pulses telling the injectors to fire, and yet 4 of them aren't firing. Sounds like 4 bad injectors to me...
