Still No Oil Pressure???? HELP!!!!
Well i replaced the O-Ring on the oil pump and replaced the Sensor in the back of the intake manifold and there is still no oil pressure. I didn't put the car back together yet i wanted too see if there was any oil pressure just by cranking it but not starting it. Any answers to why i don't have oil pressure do i have put the car back together and then start it im a little confused why i don't have any oil pressure.
Thanks
Thanks

When I did my cam install I started it briefly with out anything on the front of the motor....I just put the front cover on so the oil wouldn't spray all over.
Don't run it long...Maybe 5 sec or less.You should see some pressure.
I don't think you can build oil pressure very well by just cranking it over.

If your reading your pressure from your cluster, you may have a cluster issue...it does happen.
If not...here are some steps...
With the vehicle on a level surface, run the vehicle for a few minutes, allow adequate drain down time of 2-3 minutes and measure the oil level.
If required, add the recommended grade engine oil and fill the crankcase until the oil level measures full on the oil level indicator.
Run the engine briefly, 10-15 seconds, and verify low or no oil pressure on the vehicle gauge or light.
Listen for a noisy valve train or a knocking noise.
Inspect for the following conditions:
- Oil diluted by water or glycol - antifreeze
- Foamy oil
Remove the oil filter and install the J 42907 .
Install J 21867 or equivalent to the J 42907 .
Run the engine and measure the engine oil pressure.
Compare the readings to Engine Mechanical Specifications .
If the engine oil pressure is below specifications, inspect the engine for one or more of the following conditions:
- Oil pump worn or dirty Refer to Oil Pump Cleaning and Inspection .
- Oil pump-to-engine block bolts loose Refer to Oil Pump, Pump Screen and Deflector Installation .
- Oil pump screen loose, plugged, or damaged
- Oil pump screen O-ring seal missing or damaged
- Malfunctioning oil pump pressure regulator valve
- Excessive bearing clearance
- Cracked, porous, or restricted oil galleries
- Oil gallery plugs missing or incorrectly installed Refer to Engine Block Plug Installation .
- Broken valve lifters Repair as necessary
If the oil pressure reading on the J 21867 or equivalent is within specifications, inspect for the following conditions:
- Plugged or incorrect oil filter and/or malfunctioning oil bypass valve
- Malfunctioning oil pressure gage or sensor Repair as necessary.

You also might be able to rent this type of tool from a discount auto or something. The LSx engines are now soo widley used. you may be able to find the tool there, as it is a general automotive tool....and used by many shade tree shops across the us.
We\'re a dealer soo...I use kentmoore products.

So if anyone has anymore information they can provide me with it would be a very big help. Thank you too all of you that have already posted it has helped a lot.

Best way to install the pump is to disassemble the pump.
Put the o-ring on the pickup tube,push the tube down slightly,slide the pump over the crank snout and let the tube slide up into the pump.
You will be able to see the o-ring through the front of the pump.
Slide the gears over the snout and rotate them until they are seated.Install the front cover on the pump.
You really need to start the car to see oil pressure.If you start it briefly and your gauge still has no pressure then pull a valve cover and look for oil around the valvetrain.
If there is oil present on top of the motor then your gauge or sending unit is the problem.
FIRE IT UP!!!
