I really have not heard the term oil pump switch. There is an oil pressure switch on some small engines that will shut the engine down if the oil pressure falls below a preset pressure. These are not installed on vehicles for safety reasons. You vehicle however has an oil pressure sending unit that keeps track of the oil pressure and will warn you of low oil pressure with a red light, or by way of a gage, or both.
The Oil Pressure switch if broken off will drain "pump" the oil out of the engine very quickly.
fuel pump oil presssure switch is at back of motor just under the dist.On a v8
You are referring to two separate things. The fuel pump has a relay and not a switch. The oil filter does not have a switch but the oil pressure has a sending unit that sends a pressure reading to the gauge. Some cars have an oil pressure switch that incorporates a circuit to shut the engine down in case it were to loose oil pressure.
It does not have an inertia type fuel pump shut off switch. General Motors uses the oil pressure switch. If the oil pressure drops below 3 psi, it shuts off the power to the fuel pump,
A bad fuel pump can cause stalling. The oil pressure will show low oil on the lights or gauges but if the pressure is ok then the switch should not cause stalling.
You will have to remove the oil sending unit/switch and screew a oil pressure gauge into it's place and then start the engine and read the oil pressure.
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
The oil pressure switch is right under the alternator bracket or power steering pump
The pump is located in the oil pan, also with a sump pump and filter with screen.
There isn't one. The fuel pump receives its power from the fuel pump relay or the oil pressure switch (they are connected in parallel so that power can be provided from either source). The oil pressure switch provides power to the pump when the oil pressure reaches 4 PSI. The Fuel Pump relay supplies power to the pump when it receives a signal from the ignition switch. They are no other switches or interupts in the circuit
try taking the oil pressure switch out and taking a gauge and putting it in there and see if you have pressure there if not then it could be a bad oil pump.
fuel pump is in the tank, and the oil pressure sender switch is located on the driver side of the motor just to the right of the distributor.
