Disconnect the supply line from the three/four-way connector. Make sure the line that goes to the shutoff solenoid on the pump is properly connected. Now, start the car. Hook the hand-held pump up to the supply line (the one you disconnected). Turn the key to off. Pump hell out of the mightyvac. If the car doesn't turn off, try switching the lines at the ignition and repeat.
This assuming your shutoff solenoid is 100%.
If the car doesn't turn off with the lines in either configuration (your shutoff solenoid is definitely good, ya?) then I'd feel pretty comfortable saying the shutoff valve is defective.

Thanks Jay. Let me review what you have here. I can try it as you have said it, but I think I have already tried this. I have hooked the lines up the way i believe they should be (I can only pull vacuum on one side of this valve and then it releases when turn the key to off - so I figure that has to be the supply side - yes?). Then I disconnected the supply line (but I did so right at the injection vacuum valve and hooked the MityVac on right there. I connect the other line that goes to the fuel shut off solenoid to the other end of the ignition valve.Then I start the car.
At this point you say to turn the key off and pump the MityVac - i can do that and it will shut the engine off, but that doesn't really solve my problem. So, what I have dones is to follow the above up to the point where I start the car, then I pump the MityVac on the supply side to simulate the vacuum pump - it holds vacuum. If the ignition valve is operating properly, then turning the key off at this point should kill the engine - yes? But it doesn't. So, I think to myself - well, the ignition valve is bad. However, if repeat the above but just disconnect the the line to the fuel shut off solenoid and place my finger over the valve outlet, i can verify that that when i turn the key to off the valve opens and it pulls air through which should effectively kill the engine . . . but again, it doesn't kill the engine when I have that line (to the fuel shut off solenoid) attached.
I know that the fuel shut off solenoid is good because I can hook my Mityvac up to the brown line (w/ purple stripe) while the car is running, apply a small amount of vacuum and instantly kill the engine.
I don't know, i guess I am completely missing something here, but it seem like each of the indiviudal components is working properly until I hook them together and it no longer works.
Not sure if this makes sense - it is difficult to explain. I appreciate your help though.
