fuel pump oil presssure switch is at back of motor just under the dist.On a v8
The fuel pump switch is what tells the fuel pump what pressure to pump fuel into the fuel rail
where is the fuel pump reset button or relay switch located on a gmc sierra 2003 and how do i get to it?
There is none.
GM vehicles are not equipped with a fuel pump inertia switch.
NO...but there is a fuel tank pressure switch that tell your fuel pump when it has the proper pressure to turn the pump off once pressure is achieved.
Chevy did not use them on there trucks. Check fuel pump pressure, fuel pump FUSE and FUEL pump relay.
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,
Gm vehicles do not have inertia/reset switches.
Chevy did not use are have an Inertia switch. Ford only used them.You either have a bad fuel pump or fuel pump relay if you have no fuel pressure.
There is not one!!! The fuel pump is controlled by the oil pressure. When the oil pressure goes to 0psi the fuel pump shuts off.
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
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.
