If it's not a bad valve on the tube then I recommend the fuji floor pump. I have used it to inflate car 3 tires and it maxes at 260 psi on the gauge. Motor vehicle tire pressure gauges, the kind that pop out especially, are no good for bicycles. You need a pump with a gauge, a digital gauge, or a stand-alone analogue gauge.
