I recently changed the oilpan gasket and let the oil drain out and put it back and put new oil in it but didnt start it yet . Then next day i put a new harmonic balanser and put the engine at TDC and everything was fine until i started it ... no oilpressue!!!!! It sounded normal but im afraid of start it now .. any tip of what i can do ?
 
Are you sure the oil pressure sensor wiring didn't come loose or off? I've had that happen.

I try to strap that dam thing on with a ziptie, breadtie, shoestring, dental floss.....etc. :f-u:
 
The slide terminal that goes on the sensor comes off very easy so if you even bumped it, it is possible that it just fell off. Does the oil LIGHT stay on and no pressure on the factory gauge at all? If they are both telling you no pressure then there is something amiss. If the light comes on when you turn on the car before starting it and then goes out when she starts then it is working, or doing its little job.
Let us know.
 
I'd take off the oil pressure sensor wire and clean it up. If you have any oil leaks on your Oil filter housing your signal wire could have a bad connection . If I recall there's 2 spots where the pressure sensors connects to the harness near the alternator. (One attached to the sensor on the bottom of the OFH & another connection about 6 inches away from the sensor).

Get some contact cleaner and spray it down
The fact you were working in that area makes me think its disconnected

I broke mine when I pulled my motor so I'm actually using an alligator clip to get the signal.
Although the factory oil pressure gauge isnt the greatest

Guys dont laugh but i found the problem .. it was the driveshaft that was spinning and was hiiting the lower control arm ball joint the gauge went up after 5 or 10 seconds to normal again
