No OiL Pressure!! help please

[hardflip]

So I just replaced the oil pan gasket on my 89 5.0 and when I started it up it made a funny noise and the oil pressure did not go up. In the book it says to turn it off after a minute if the pressure doesn't rise and so I did. What the hell did I mess up on?

All you did was replace the gasket? What all did you have to disconnect to get the engine up enough to replace it? You did remember to refill with oil, right? (had to ask)

are you sure the pick up to pan clearance stayed the same?

can you prime the pump with a drill? pull the valve covers off so you can see if pressure builds and makes it up top.

good luck.

yeah, didn't forget the oil did ya? I would also like to know how you changed the oil pan gasket, and how long did it take...

Just a simple thought. Check to make sure the sending unit wire didn't become disconnected, or possibly you forgot to put it back on if you disconnected it for the install. Just a suggestion to cover something simple that would make it read 0 pressure.

That was my first thought (disconnected sending unit) - but working below the car it seemed unlikely, and he said something about the car making untoward noises.....didn't sound, uh, like a hopeful prognosis.

is the oil pump shaft still in the oil pump? get a flash light and look down the hole.

if its missing go fishing with a small magnet on a stick. be patient... once you grab it try to maneuver it into the hole and remove magnet by wedging long screw driver on the pump shaft.

it sucks and take along time but you can get it if this is the problem
