Will oil light come on if oil pump is bad?
Typically if the oil light is on it is an indication that the oil pressure is low. This isn’t an automatic indication you have a problem with your oil pump, as there could be a leak, or your engine could be burning oil. The problem could be solved by checking the dipstick and adding oil if it is low.

Why is the oil light on but not on?
However if the light only turns on on idle and goes off when you increase the rpm, then the pump is a suspect as well. If this is a high mileage engine, in addition to a worn oil pump or a faulty oil pressure sensor, the fault could also be caused by worn bearings within the engine.
