HELP!!! Oil Pump

I have a 95 Trooper that I bought used. The oil pressurer gage was showing low after I had the Trooper a few months. sO WE THOUGHT WE WOULD REPLACE THE OIL PUMP. Does anyone know how to replace the oil pump in a 95 3.2 liter??? We are having a heck of a time getting this done. HELP!!

Your problem is probably a dirty pluged oil pickup on the pump that is in the oil pan. You might want to try to add a can of sea foam, drive it for a could hundred mile and change the oil when it is good and hot. Or take it to a place the will do a hot engine flush.

Or it could be a bad oil pump.
