Something else to vrify is that the rack cycles back and forth when you switch the key on. The ECU controls fuel by moving the rack in response to your input on the pedal.

So the fuel rack moves starting in the back (firewall side) then to the front and back to the back when the key is turned on. When I have the wife crank the engine over and pump the accelerator the fuel rack doesn't move. Should it move due to the pumping of the accelerator? Using a mirror I can see the fuel pistons moving up and down. Does this sound like the ECU is not telling the IP to give fuel? I'm assuming that this is what happens when you turn off the engine when it is running.
