the pressure of oil that the oil pump is pulling?
Your car or truck will begin losing pressure(meaning you will not be able to drive forward in a normal speed)
no, however the fuel pump has a secondary route through the oil pressure switch.If the fuel pump relay goes out the pump will run through the oil pressure switch after the engine gets oil pressure. this results in extended engine cranking time before the engine will start
Low oil pressure or fluctuating oil pressure.
The oil pressure is dropping at this time. A clogged oil filter, clogged oil pump screen or failing oil pump can be the cause.
