Fuel pump not getting power

Asked by Jun 05, 2017 at 12:03 PM about the 2004 Toyota Corolla S

Question type: Maintenance & Repair

I have a 2004 toyota corolla s, and it's not getting
any power to the fuel pump. We changed the fuel
pump out and still nothing. We even took both
pumps and hooked them directly to a power
source and they both came on. Fuses are good,
and relay is good.

I need to ask a couple of questions? Engine cranking, do you have spark at the plugs and fuel injector pulse? If the answer is no, I don't believe the fuel system is the problem? I don't know what testing you have done? Any applicable trouble codes? If you have narrow it down, check voltage and grounds at relay, Voltage for load side of relay comes from efi relay. In the diagram looks like open switch on one side, the other side of relay, looks like a coil in diagram, that side has to have voltage and ground. Voltage for the control side of relay comes from ignition switch. The control side is grounded by pcm.
