Camry just quit running. I can't hear fuel pump, so I first replaced EFI relay. Still couldn't hear anything so I removed fuel pump and hooked directly to 12V source. Fuel pump works. I placed back into the auto still no pumping. Is there an additional relay? Manual indicates there is but I am unable to locate?
The engines oil pressure switch has a third wire which is connected to the fuel pump. The oil pressure gauge may work although the third wire to the pump may be at fault causing your delimma
Once the engines oil pressure reached the normal operating range the computer shuts down the oil switches third wire to the pump and the relay takes over until you shut the emgine off
There is not one on the 4-cyl just for the fuel pump. It is supplied by the EFI 15A fuse thru the EFI main relay and the circuit opening relay. See here p 177

On the V6 it is similar, see p 575
