I see a lot of posts like this, with almost no information at all. Every car is different, so without knowing the make/ model/ engine you're asking about, it's impossible for anyone to help you with this. On some cars, you have to remove part of the exhaust system. Some require removal of other parts as well. Some require special tools the average joe isn't likely to own. Try reposting this again with a bit more info please.
You need to remove the oil pressure sender by the oil filter and put a manual gauge in to see what your oil pressure actually is. The oil pump is fairly easy to replace, just drain out the oil and remove the starter. You can get to the oil pan bolts and then lower the pan. The oil pump is held onto the rear main bearing cap by one bolt. Remove it and lower it keeping in mind that the oil pump drive shaft will come out with it. Make sure the shaft hasn't rounded off, if its worn, replace it.
Raise the truck using the proper equipment. Use a ramp or a jack and jack stands to support the vehicle securely by following all directions for use provided by this equipment's manufacturer.
Drain all oil from the Silverado by placing an oil drip pan under the vehicle's engine block, directly under the oil drain plug. The drain plug is located on the oil pan, between the vehicle's tires underneath the vehicle. Use a wrench to loosen and remove the plug allowing the oil to drain into the pain below.
Notice the various items attached to the oil pan or in the way of the oil pan dropping. For the oil pan to drop, remove the negative battery cable, front differential (only for four-wheel drive vehicles) and the under body shield by using a wrench or socket set.
Remove the oil pan shield by loosening the four bolts holding it in place along the edges of the shield. Then, remove the cross brace, oil filter, the transmission to oil pan bolts and the oil level sensor.
Follow the removal of those pieces by removing the bolts from the two front wiring harness, the engine wiring harness retainer, engine oil cooler pipe to oil bolts and the transmission oil cooler pipe retainer using a wrench. Located the closeout covers and bolts located on each side of the engine and remove them.
Disconnect each of the oil pan bolts using a wrench that will allow the oil pan to drop. The oil pan gasket will also fall off and replacement should occur before reinstalling the oil pan.
Go down to your parts dealer (hopefully Auto Zone :)) and get the gasket as well as oil and oil filter (unless you are going to use the old oil and have something to catch it in). Drain the oil. Remove the bolts on the oil pan. Remove it and the old gasket. Check to see that ALL of the old gasket has been removed. Clean the mating surfaces. Put new gasket in place on the pan and place to the block. Install bolts and tighten to specs. You can get the bolt torque specs from AZ as well. Add oil before starting engine
If all the bolts are off, then the gasket is holding the oil pan in place and your going to have to tap it with a mallet, Not a hammer but a mallet so you don not damage the oil pan. Good luck and hope this helps.
The worst part will be either lifting the engine to the point that it clears obstructions, or to remove the obstructions, or both. Lifting the engine requires that you disconnect the motor mounts and who knows what else. Once everything is out of the way you can drop the pan. I hope this helps.
