3vze v6 engine no power to fuel pump can only

OK...for years the relay for the fuel pump on a Toyota is called the "Circuit Opening Relay" This relay is controlled by another relay...the EFI Relay. Both of these relays are fused. A 10amp Ignition fuse. A 10amp EFI fuse #3. A 10amp EFI #2 Fuse. Where are these fuses and relays? Start by checking under the Hood.

Switch the horn relay with the c/op relay to see if it’s the relay. I don’t know why they have to give u complicated answers.

To answer your question specifically it would be no. There
is no inertia switch that feeds the fuel pump that can be turned off or reset . The engine control computer turns on a series of two different relays to control power to the fuel pump. When in the start position the circuit opening relay and the fuel pump relay or both energize causing the fuel pump to run at full pressure or fast speed. From there the engine control computer determines which demand is on the fuel pump and either turns off the fuel pump relay and leaves
the circuit opening relay on to supply power through a resistor to slow the pump down for less demand. The EFI main relay is the main supply relay to both of these sub relays. The fuel pump is powered up ultimately by the 20 amp EFI number one fuse. All of these components are located in the fuse box under the hood. If the circuit opening relay is not working it's powered up by the 10 amp
ignition fuse inside the vehicle. It's unlikely it is the 10 amp ignition fuse because that powers up a lot of other things also.

There are several "relay blocks" around the car. Info on what relays are in each one is printed inside the block cover, which is not a lot of help to start off with.

It appears to me that not all Camrys have that relay fitted, some instead only having a fuse. The 1MZ V6 has a big enough pump that it has a relay in block 5, under the hood on the left side looking forward.

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

Sounds like your fuel pump has died based on what you said.

It supplies the EFI Main relay, which in turn powers the fuel pump, ignition switch, and starter relay. In addition it powers the ECM computer, so that if you wish to clear a trouble code from there, you pull the EFI fuse for 30 sec. See here p177

The pump gets power from the circuit opening relay and the EFI main relay, which are supplied through the EFI fuse. p219 here

Check the EFI main relay, the circuit opening relay, and the fuel pump relay. Inside the fuel pump relay there is a switch controlled by a coil. During start, the fuel pump gets full power for a couple of seconds to build up pressure. Once pressure is good, the fuel pump relay is supposed to switch (via the coil) the fuel pump to reduced power. If the coil in the relay is bad, the reduced power setting is not available and the fuel pump will run at full power all the time. At this heavy current draw, it won't be long until the EFI fuse blows. This would also give more pressure than is necessary to the cold start fuel injector which runs on a timer. This extra pressure during the time that the cold start injector is operating may be the reason the engine is flooding with fuel.

So you replaced the fuel pump because it didn't make noise? did you check for power at the Blue/Black wire? The Circuit Opening Relay powers the pump. Make sure to check ALL the fuses. Ignition and EFI fuses? does the Check Engine ligth come on with key on? it should, did you check the EFI MAIN relay
