Tried to search this topic, only one thread came up. Finally got the flexplate replaced on the truck. After sitting for a couple months, it fired right up, but I noticed Oil pressure was at 0. I immediately shut it off. Checked my sensor connections, everything looked good and the gage used to work. Pulled the dr side valve cover and fired it up for a sec. Sure enough, no oil. I've never replaced an oil pump before. Parts store sells them for 16 bucks or something. Anything tricky? I figured Id pick up a Chilton's manual.
