ok if you get 12v at the red wire at the injector resistor but still have no injector puls check to see if you have 12v at each red/blk wire to the injectors.if you don't you have a open from the injector resistor to the injectors. if you do check the ohms on the injectors 1.5 ot 2.5 ohms.ok if that passes you will need to do a continuity test from the injectors control side to the computer take the computer connectors off first if you get continuity is the computer if you don't you have a open in the wires from the injectors to the computer.
