Oil pressure freak out

Oil pressure freak out
Hey guys, I was turning into my neighborhood when I looked at my oil pressure gauge (yes, it's the factory one for now) and it was below 0. I immediately pulled over and saw that I had oil and there were no leaks. The engine sounded fine and the temperature was normal. I had another Mustang guy pull over and said that if I didn't have oil pressure I would know it. So we decided to drive it the two blocks home. The car ran fine and no noises or anything weird. When I turned to key to the on position it went to zero, then when I turned it on it went below.
If I didn't have oil pressure would I know it by horrible sounds or what? I'm hoping its just the pressure sending unit, but I'm freaking out because it's a brand new motor and I can't afford another one, so I'm not thinking straight.

I just swapped the oil filter and put a dry one on. Turned to car on for literally 10 seconds and it filled up the dry oil filter. So at least I know I have circulation. I also put in an order for an auto meter ultra lite oil pressure gauge. I'm just hoping it's the POS sending unit.

Your on the right path, getting a real gauge to protect your investment. My stock sending unit crapped out on me also, or it was the gauge itself. It would fluctuate rapidly every once in awhile.
Keep us posted

Mine went below the red line. That makes me think that it's the sending unit, but my OCD is kicking in and I'm not thinking with a neutral mind. When you put the key on the "on" position, it goes to the red line, but when you crank it over it goes below the red line. Like I said it filled up the oil filter in less than 10 seconds, is not making any funny noises, and besides the gauge I would not think anything is wrong, but I can't shake that "what if" out of my head. That's why I'm making the post.

Ok. Cool. That's what I was hopping to hear. I didn't hear or feel anything strange at all. It's funny, the very moment before I looked down at the gauge my exact thought was "god what would I do if I ever saw no oil pressure" (looks down at gauge) "kinda like that...................................OH F$#@!!!!" True story.

OMG I hit the mental G-spot when I felt the old sending unit was 90% broken off. Ahhhhhhhhhhhhhhh soooooooo relived. I couldn't take it anymore, I bought one from the local auto part store until Wednesday when I get my auto meter gauge. lol I'm taking the old unit to the shooting range this weekend. Payback for the heart attack and sleep I lost over this. lol

ya know you could of verified this was the issue in less than 10 sec.......the gauge works off of resistance...therefore next time, just unplug the connector at the sending unit and ground it = gauge should read up to the H.....IF it does, you know the circuit is fine and thus you have a bad sending unit

Didn't know that. lol Oh well. I'm putting in a real gauge no matter what. I already bought my triple gauge pod, and I need to do an auto meter water temp gauge too, so oh well. I was going to do it anyways, but I was going to wait until after I finished my coil overs.
