I am brand new to this site and don't know where to get info on why my 1991 tbi 350 swap into my 1984 k20 injectors arent spraying. I have spark. New ignition module and cap. Brand new airtex pump. I pulled the harness out of the donor truck still attached to the motor and spliced into the computer plugs. The fuel pump comes on with the relay as it should with the key on and cycles off but I don't hear it when it's trying to start. Was wondering if someone could point me to a wiring diagram to help.
