Okay so this is a fun one. Please tell me its fixable.
Okay so I got the car from a personal seller. And after about 2 weeks when my gas reached a quarter of a tank it would idle rough and stall when I slowed down to turn or come to a stop light. Then you could turn off the car and restart it and be on your way till it happened again. Mind you this only ever happened at a quarter tank of gas once, I filled her up again all problems went away. The other day I parked my car and I had a half a tank of gas and went to start it and it wouldnt start. It cranks over but wont start? Ive asked around and gotten several diff answers any idea what this could be?

The best way to catch this culprit if it involves the fuel system is to hook up a fuel pressure gauge and monitor the pressure. If not it next time it refuses to start do below to determine if its fuel or spark problem something has to give-

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil, distributor pick-up coil, ignition control module, cam and crank sensors-
