Right, but my main problem with this is that I have a fuel vaporizer which delivers fuel vapors into my PCV hose. So, the engine will still be getting fuel.
(now that I think about it I wonder if I could run only on fumes. might burn out the engine though),


anyways, this is why I need to use a different wire, like the crank position sensor.


I would love to be able to mimic exactly the electrical circumstances that take place when I turn the key back a notch to the ACC position, then back to the run position. This way the car will be ready to fire back up when I release the clutch pedal in 5th gear !
