What you say makes sense to me. It brings this funny story to mind:

"I am reminded of a story from years ago when GM throttle body fuel injection was a new thing on cars. A customer had his two-week-old Cadillac towed into the dealership with a "no-start" problem. For two weeks, every technician at the dealership worked on it trying to start it but to no avail. We checked for spark, compression, timing; pulled codes; set codes; checked fuel pressure; checked to see if the bumpers fell off... Every conceivable thing was done to this vehicle we could think of and still no start. Finally, one of the techs decided to check the fuel spray/pattern from the throttle body. He got a bit of the spray on a piece of paper, tried to light it with a cigarette lighter, and it did not ignite. The tank and fuel system were drained, filled with fresh fuel, and the car fired right up.

After contacting the owner, who then spoke to his younger children, it was discovered that the kids were playing "gas station" with the new Cadillac and garden hose. ---Bruce in Oregon via Rock Auto"
