39 actually, but 7 is definitely under spec.
There's no easy way to do it but I'd almost put a mech. gauge on it and double check that pressure.
Did fuel spray out or did it stream out? Meaning, did it seem like there was good pressure.
Could be the Fuel Rail Pressure Sensor is bad. If it sees low pressure it will send more voltage to the pump and actual pressure might be so high that the car floods almost instantly.
