Solution

1. Preparation

Gather tools and parts before starting.
Tools Required: Oil pressure gauge, socket set, wrench set, oil filter wrench, drain pan, funnel.
Parts Required: New engine oil, new oil filter (if needed).
Ensure the engine is cool and parked on a level surface.

2. Check and Refill Engine Oil

Sub-steps:
1. Remove the dipstick and wipe it clean.
2. Reinsert the dipstick and pull it out again to check the oil level.
3. If low, remove the oil filler cap and add the appropriate type and amount of engine oil.
4. Replace the oil filler cap securely.

3. Replace Oil Filter (If Necessary)

Sub-steps:
1. Position the drain pan under the oil filter.
2. Use the oil filter wrench to remove the old oil filter.
3. Apply a small amount of new oil to the rubber gasket of the new oil filter.
4. Install the new oil filter by hand until snug, then tighten it slightly more with the wrench.

4. Test Oil Pressure

Sub-steps:
1. Remove the oil pressure sending unit from the engine.
2. Install the mechanical oil pressure gauge in its place.
3. Start the engine and observe the oil pressure reading on the gauge.
4. If the pressure is low, further investigation of the oil pump is necessary.

5. Inspect and Replace Oil Pump (If Necessary)

Sub-steps:
1. Disconnect the battery to ensure safety during repairs.
2. Remove any components obstructing access to the oil pump (e.g., timing cover).
3. Unbolt the oil pump from the engine block.
4. Install the new oil pump and torque bolts to manufacturer specifications.
5. Reassemble any removed components, reconnect the battery.
