It is possible but it is more likely that it is from the wires going to the fuel pump that is shorting to earth.Check and follow those wires from the pump to the fuse box that none of them are exposed without its insulation.It is a tough job to trace that problem sometimes without a multimeter.

The fuel pump may be draining too much current. Make sure you have the correct fuel pump installed. Also, it could be a blockage on the inlet of the fuel pump (ex. maybe touching the bottom of the fuel tank). Or even a kinked line making the pump work extra hard and thus using more current than fuse can handle.

2000 toyota sienna enging knock when start up. engine knocks briefly than goes away after sitting a couple hours


it may be from a complete drain back of sump oil
check that you have a good quality oil filter in place with an anti-drain back valve in place ( cheap filters omit this valve)
check the viscosity of the oil you are using as it may be to light for the conditions

2008 sienna, starts then after a few seconds quits, starts no problem but then stalls after a few seconds or when you press the accelaerater. needs new fuel filter i guess. Where is it located.


The fuel filter is located in the engine compartment, at the inlet line to the fuel rail. Be sure to relieve the pressure in the system first by removing the fuel pump fuse and cranking the engine a few times. When installing the new filter use new O-rings and tighten the lines to 22 ft. lbs.

My Toyota Sienna keeps stallling


If the car stalling then the owner of the car should check on the fuel pump assembly. prepare the tools and equipment in servicing the fuel pump,the fuel lines and the fuel filters.In the fuel pump you have to locate the fuel pump,disconnect fuel lines from the fuel pump,remove fuel pump from the engine,dis-assemble fuel pump, check the diaphram for defect , replace defective parts,assemble and install the fuel pump.
In checking the fuel lines : prepare the tools or equipment in servicing the fuel lines .So that the fuel will flow freely and no abstraction within the fuel lines.locate the the fuel lines ,visual inspection on dual line for leakage, disconnect lines at fuel pump and fuel tank .use compress air to remove sediment on fuel lines,re-install fuel lines to the unit.
the fuel filters :prepare the equipment or tools in checking the fuel filters that is going to be used.So that when fuel filters is removed ,no fuel will spill on the vehicle and no parts are lost or broken.Locate fuel filter,disconnect lines at fuel filter ,observe safety practices ,If the fuel filter is dirty then you have to clean it but if it is worn out and not anymore to be used then install new fuel filter.
