Where is the relays for a 2002 toyota camery fuel pump and the computer sencer for the fuel injection

Sounds more like ignition switch to me.

Check the fuel pump relay and fuse

It is located in engine fuse box, and is marked C/O (circuit open relay) this is your fuel pump relay, good luck.

The electronic fuel injection system in your 2007 Toyota Corolla is an extremely technologically advanced, computer controlled, engine fueling system that consists of hundreds of parts, sensors, solenoids, relays and electrical circuits. It also consists of a computer-controlled pump as well as high-pressure lines and fittings that deliver the fuel from the fuel tank to the injectors. The computer system that controlls your fuel injection system has nearly 100,000 times the computing ability of the computers that were on the Apollo space craft that put put man on the moon.
To say something as simple as "fuel injection problem" and expect a viable "solution" for your problem is like saying "water problem" at Niagra Falls and expecting somebody to fix it for you.

What kind of "fuel injection" problem? Have you tried interfacing with the computer that controls your fuel injection system? If so, what did it tell you? If not, that would be a real good place to start.

It is called the Circuit Opening Relay, and should be behing the glove compartment, which you have to remove from the dash.

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.

The fuel pump doesn't have a single designated fuse, it gets electrical input voltage from several sources, the fuses tart you need to check are the 7.5A ignition fuse, the 15A EFI, the 15A starter. There are two relays that are involved, the circuit opening relay located behind the glove box and the EFI main relay located in the fuse box under the hood, the most common problem when there is no fuel pressure is the fuel pump, check all the fuses and substitute the two relays to see if it solves the problem.

The fuel pump will not be supplied power to work if the sensor that is driven by ignition pulses from the distributor is faulty or the pulses are not getting to the sensor.

check the fuel pump relay and the crank sensor give these websites a try www.alldatadiy.com and www.autozone.com if all fails stop by your local library and get your hands on a Haynes auto repair manual for your car wish you the best of luck Michigan Man.

THESE ARE NOTORIOUS FOR FUEL PUMPS AND FUEL PUMP RELAYS, TRY A RELAY FIRST, THERE CHEAPER
