i have 0 oil pressure...did my pump go bad..the motor is brand new 1 hr runnung time...i had good pressure than 0...i than used a drill and prime tool ..and still noting..

if the pump still turns ok using the prime tool, have you tried turning it the opposite way from the way you first turned it?
if this is not the problem, then I would drop the oil pan and check to see if the pickup tube is still attached to the oil pump, sometimes they vibrate and fall off the pump which then can't get any oil to pump so the pressure is 0.
I'm assuming you're reading the oil pressure with a good gauge BTW.
