The truck has a few issues. it sometimes (not often) would idle really rough when starting cold. a few taps on the gas and back to normal. then the oil pressure gauge would drop to zero when not applying gas. (oil level was good but oil needs to be changed). after accelerating the pressure picked back up to normal. Then two days ago. I stopped at a light the pressure dropped to zero the truck sputtered and stalled. would restart but immediately sputter and shut off. I then changed the oil pump and cleaned the screen. now it just cranks and won't start. I did notice antifreeze dripping from the transmission bell housing.


Suggestions? Oil pressure switch? Crank Sensor?
