I believe that if you remove the cold-start injector, you can also remove the thermotime switch, and the last part of the wiring that goes to the thermotime switch, because it is just an extension and plugs in via a pair of bullet connectors near the #2 injector. I don't know if you want to cut off the bullet connectors, but it might be good to just tape them off, in case you want to reinstall the coldstart stuff. Later, if you want to remove the cold-start stuff permanently, I'd follow the thermotime/coldstart injector wires as far back to the ECU as possible and cut them there. Where'd you get a custom fuel rail? I'm having trouble finding sources. thx
