This stared all of a sudden. Shut the engine off. Then it would not
start again. Fuel pouring out onto the ground from behind the fule
pump. This is a 6 cylinder motor with the pump up front.
Quickly I ran back to the filler cap to help stop the gas from gushing
out. When I did, the air escaping (or coming in?) sounded like a set
of air brakes. Wow!
Went to the parts store and made sure that I bought the specific gas
cap for this car. Same problem with gas gushing out after the car has
been warmend up and then shut off. Same air rushing from the cap when
I unscrew it.
Went through the whole procedure again, this time with no cap on at
all. When I shut down the engine, no leaks.
So the car runs, stops and starts fine with no cap.
What should I be looking for in this situation?
