Someone told me that oil pumps rarely go out so I should pull the distributor and check to see if the tab at the bottom is broken, but this vehicle has Electronic Ignition, and no distributor, is there anything other than the oil pump which would cause this problem?

ENGINE LUBRICATION SYSTEM
Engine lubrication system is a force-feed type. Oil is supplied under full pressure to crankshaft, connecting rods, camshaft bearing and valve lifters. A controlled volume of oil is supplied to rocker arms and push rods. All other moving parts are lubricated by splash or gravity flow. Oil flows through oil filter before entering main oil gallery.

Removal & Disassembly
Remove oil pan. See OIL PAN under REMOVAL & INSTALLATION. Remove oil pump baffle. Remove oil pump retaining bolts. Remove oil pump and pick-up tube assembly. Remove oil pump drive shaft. Remove and replace gasket. Disassemble oil pump. Note direction of component installation for reassembly reference.
Inspection
Inspect components for damage. Measure rotor end clearance, drive shaft-to-housing clearance and idler gear-to-driver gear clearance. Check clearance between pressure relief valve and bore. Measure relief valve tension. Replace oil pump assembly if measurements are not within specification. See OIL PUMP SPECIFICATIONS table.
