Arthur,

I rechecked the regulator. There certainly doesn't appear to be any gas coming out. I sniffed the hose and thought I detected a little gas, but it was pretty faint. How subtle might this be? (The regulator is the round device at the rear of the engine on the fuel rail with a vacuum hose on it, right?)

Now no codes (not even one flash) come from my reader on pin 19 or from the pushbutton module. All the other pins give readouts (which I have cleared) but not the one that I'm having trouble with! The LED comes on when I press the button, but no flashes. Of course, the Check Engine Light is still on.

Greg
