Run a vacuum line to a switched electric solenoid Then to the vacuum shut off. There must be a hole in the line ie vacuum leak between the solenoid and the shut off valve just a small one to release vacuum to the shut off valve so it can restart quickly. poke a hole in the line or use a hot sewing needle in the plastic part just before the shut off valve on the injection pump. It has to be able to bleed vacuum after the solenoid closes but not to much that the vacuum cant over come the leak and still close the shut off valve.
a vacuum leak in the car will drive you nuts from the noise
