When leaking siphon jet causes fuel starvation it's not uncommon for after a rest, environmental changes will allow a little bit of fuel to siphon over to the pump and get the car to start but usually run terribly and maybe just fifty feet.

If the car stalls and putting in two gallons of fuel puts you back in business you are almost assured of the siphon jet o-ring failure.

Test six is in the hidden menu. YouTube or google is your friend.

Bring up test six on the dashboard and it will report real-time how many liters of gas are in the left side and right side tank.
