I drove the car fine, parked in my garage, i removed one vaccum hose that goes into the fuel line to feel if it was not cracked or something, put it back on thats it, then after like an hour or so started to crank it, starter worked but the car doesn't start, i believe the fuel was low so i put in fuel but still won't start, i heard a bang noise from the engine, i guess due to misfire cause looks like the fuel has air lock its not reaching the engine, fuel pump comes on when i turn the ignition. i don't know whats going on.
