The oil pressure sending unit is located slightly above the oil filter. You will need a flashlight to find it. It may be hard to recognize it because it should have a heat shield around it as well. Look for its wire coming down from the engine compartment and follow it to the oil pressure sending unit. Drain your engine oil and remove the oil filter to make changing the oil pressure sending unit easier.Locate the oil pressure sending unit behind the rear of the intake manifold. It is a black plastic tube about 3-inches tall.
-------------- This will help.Thanks.Helpmech.

1997 gmc sierra 3500 won't start

When you turn the ignition to start, do you hear the starter turning and the solenoid engaging the flywheel ? test your starter by jumping it and see if the engine turns over. If this works, then you might consider in checking fuel pressure. Do you have any codes in your ECM ?

I have a 2003 gmc sierra 5.3 liter vortec why does my truck leak oil only under pressure

because your oil pressure rises to around 40psi when running and will leak at the weakest place,check your oil sending unit first and seals.

Oil pressure sending unit

Hi there;

Your looking foer the oil pressure sensor on the 2004 8.1L.
You will find it located directly behind the EGR valve threaded into the block just to the drivers side of the center bolt for the transmission to block connection.

Thanks
Farrout!
